Description

Technical Field

[0001] The present application relates to the field of lenses, and in particular to an optical lens, a camera module and an electronic device. Background Art

[0002] With the continuous development of portable electronic devices such as mobile phones, users are increasingly demanding higher performance from camera modules in these devices. Existing camera modules generally use multiple fixed-focus lenses combined with digital zoom to achieve "jump zoom." However, jump zoom fails to meet user photography needs. Furthermore, the lens positions in existing fixed-focus lenses with digital zoom are fixed, and existing fixed-focus lenses lack optical image stabilization. Therefore, existing camera modules cannot simultaneously achieve continuous zoom and optical image stabilization. Summary of the Invention

[0003] The present application provides an optical lens, a camera module and an electronic device that can achieve simultaneous continuous zoom and optical image stabilization.

[0004] In a first aspect, the present application provides an optical lens. The optical lens includes a first lens group, a second lens group, a third lens group, and a fourth lens group arranged in sequence from the object side to the image side, the first lens group being used to change the propagation direction of the optical axis from a first direction to a second direction, the first direction being different from the second direction; during an anti-shake process of the optical lens, the first lens group rotates about a first direction, or about a second direction, or about a third direction, or about the first direction and the second direction, or about the second direction and the third direction, or about the first direction and the third direction, or about the first direction, the second direction, and the third direction; wherein the third direction is different from the first direction and the second direction; during a zoom process of the optical lens, the first lens group and the second lens group are fixed lens groups, and the third lens group and the fourth lens group are movable along a second direction; the first lens group has positive optical power, and the second lens group has negative optical power.

[0005] It is understandable that during the optical image stabilization process of the optical lens, the first lens group can rotate in multiple directions, which is conducive to achieving optical image stabilization of the optical lens, thereby improving the imaging quality of the optical lens. In addition, since the third lens group and the fourth lens group can move along the optical axis in the second direction, the optical lens can achieve continuous zoom. In addition, the third lens group and the fourth lens group are not likely to take up too much space in the first direction, thereby reducing the length of the optical lens in the first direction, improving the space utilization of the optical lens, and thus facilitating the miniaturization of the optical lens. Therefore, the optical lens can achieve optical image stabilization and continuous zoom at the same time.

[0006] It's understandable that the first lens group has positive power, constricting light; the second lens group has negative power, diverging it, narrowing the field of view. The combination of the first and second lens groups creates a positive-negative lens structure that better addresses aberrations like chromatic aberration. By simultaneously achieving optical image stabilization and continuous zoom, the optical lens offers greater freedom and superior image quality.

[0007] It is understandable that, on the basis of the optical lens being able to simultaneously achieve optical image stabilization and continuous zoom, the optical lens can be able to achieve high imaging performance while meeting the requirements of high zoom ratio and continuous zoom by rationally utilizing the optical power configuration of the first lens group and the second lens group, and by rationally utilizing the coordination of specific optical lenses with other parameters, such as aspheric surfaces, focal lengths, refractive indices, the total optical length of the optical lens system, the axial thickness and the radius of curvature, etc.

[0008] In one possible implementation, the second direction includes a first sub-direction and a second sub-direction in opposite directions, the first sub-direction being the direction from the third lens group to the second lens group; in the process of zooming the optical lens from the telephoto end to the super telephoto end, the first lens group and the second lens group are fixed lens groups, and the third lens group and the fourth lens group move along the first sub-direction; in the process of zooming the optical lens from the super telephoto end to the telephoto end, the first lens group and the second lens group are fixed lens groups, and the third lens group and the fourth lens group move along the second sub-direction.

[0009] It is understood that because the third lens group and the fourth lens group can move along the optical axis in the first sub-direction or the second sub-direction, the optical lens can achieve continuous zoom. In addition, the third lens group and the fourth lens group are unlikely to occupy too much space in the first direction, thereby reducing the length of the optical lens in the first direction, improving the space utilization of the optical lens, and further facilitating the miniaturization of the optical lens.

[0010] In one possible implementation, during the process of zooming the optical lens from the super telephoto end to the macro state at the super telephoto end, after the third lens group moves along the first sub-direction, the fourth lens group moves along the second sub-direction; or, the fourth lens group moves along the second sub-direction.

[0011] It can be understood that the optical lens can achieve zooming from the super telephoto end to the macro state of the super telephoto end, the optical lens can achieve continuous zooming, and the shooting performance of the macro state of the super telephoto end of the optical lens is better.

[0012] In a possible implementation, when the optical lens is zooming from the telephoto end to the macro state at the telephoto end, the third lens group moves along the first sub-direction.

[0013] It can be understood that the optical lens can achieve zooming from the telephoto end to the macro state at the telephoto end, the optical lens can achieve continuous zooming, and the shooting performance of the macro state at the telephoto end of the optical lens is better.

[0014] In a possible implementation, the third lens group has positive refractive power, and the fourth lens group has negative refractive power.

[0015] It is understood that the third and fourth lens groups can cooperate to achieve focus and zoom of the optical lens and camera module, thereby improving the imaging quality of the optical lens and camera module. The third and fourth lens groups work together to better address aberrations such as chromatic aberration, providing the optical lens with greater degrees of freedom and better imaging quality.

[0016] It is understandable that, on the basis that the optical lens can simultaneously achieve optical image stabilization and continuous zoom, the optical power configuration of the third lens group and the fourth lens group can be reasonably utilized, and the coordination of specific optical lenses with other parameters can be reasonably utilized, such as aspheric surfaces, focal lengths, refractive indices, the total optical length of the optical lens system, the axial thickness and the radius of curvature, etc., so that the optical lens can achieve high imaging performance while meeting the requirements of high zoom ratio and continuous zoom.

[0017] In one possible implementation, the optical lens satisfies: 0.2<|ΔG4 / ΔG3|<5, where ΔG3 is a distance that the third lens group moves along the optical axis in the second direction, and ΔG4 is a distance that the fourth lens group moves along the optical axis in the second direction.

[0018] It can be understood that by limiting the absolute value of the ratio of the distance ΔG4 of the fourth lens group moving along the optical axis in the second direction to the distance ΔG3 of the third lens group moving along the optical axis in the second direction within the range of 0.2 to 5, the respective moving strokes of the third lens group and the fourth lens group during the continuous zooming process are close, and the stroke when the driving mechanism drives the third lens group and the fourth lens group to move is smaller, which is conducive to the miniaturization of the optical lens. At the same time, the structure of the driving mechanism is simpler and more user-friendly.

[0019] In one possible implementation, the optical lens satisfies: |(ΔG3+ΔG4) / fs|<5, where fs is the focal length of the optical lens at the super-telephoto end.

[0020] It can be understood that the smaller the value of |(ΔG3 + ΔG4) / fs|, the smaller the distance ΔG3 of the third lens group moving along the optical axis in the second direction and the distance ΔG4 of the fourth lens group moving along the optical axis in the second direction of the present application compared to the solution with the same focal length of the optical lens; compared to the solution with the same distance ΔG3 of the third lens group moving along the optical axis in the second direction and the distance ΔG4 of the fourth lens group moving along the optical axis in the second direction, the focal length of the optical lens of the present application can be larger. Thus, by limiting |(ΔG3 + ΔG4) / fs| within a range less than 5, reducing the distance ΔG3 of the third lens group moving along the optical axis in the second direction and the distance ΔG4 of the fourth lens group moving along the optical axis in the second direction, or increasing the corresponding focal length of the optical lens, it is beneficial to achieve the miniaturized setting of the optical lens.

[0021] In a possible implementation manner, the optical lens satisfies: 1.0 < f1 / ft < 5, where f1 is the focal length of the first lens group and ft is the focal length of the telephoto end of the optical lens.

[0022] It can be understood that by limiting the ratio of the focal length f1 of the first lens group to the focal length ft of the telephoto end of the optical lens within a range of 1.0 to 5, the optical anti - shake performance of the first lens group is improved, thereby improving the optical anti - shake performance of the optical lens.

[0023] In a possible implementation manner, the optical lens satisfies: - 10 < f12 / f3 < 0, where f12 is the combined focal length of the first lens group and the second lens group, and f3 is the focal length of the third lens group.

[0024] It can be understood that the smaller the value of f12 / f3, the longer the focal lengths of the first lens group and the second lens group, and the shorter the focal length of the third lens group; the larger the value, the shorter the focal lengths of the first lens group and the second lens group, and the longer the focal length of the third lens group. Thus, by limiting the ratio of the combined focal length f12 of the first lens group and the second lens group to the focal length f3 of the third lens group within a range of - 10 to 0, the optical anti - shake performance of the first lens group is improved, thereby improving the optical anti - shake performance of the optical lens.

[0025] In a possible implementation manner, the optical lens satisfies: 0.2 < ft / fs < 0.8.

[0026] It can be understood that by limiting the ratio of the focal length ft of the telephoto end of the optical lens to the focal length fs of the ultra - telephoto end of the optical lens within a range of 0.2 to 0.8, the value range of ft / fs is relatively wide, the value ranges of the zoom ratio and the zoom magnification of the optical lens are larger, and the optical lens has a larger field - of - view coverage range.

[0027] In a possible implementation, the optical lens satisfies: 1 < fse / fte < 5, where fse = (fs × 43.27) / IHs and fte = (ft × 43.27) / IHt, IHs being the image height at the ultra-long focal length end of the optical lens and IHt being the image height at the long focal length end of the optical lens.

[0028] It can be understood that the smaller the value of the zoom ratio fse / fte of the optical lens, the smaller the zoom ratio, and the larger the value of the zoom ratio fse / fte of the optical lens, the larger the zoom ratio. Thus, by restricting the zoom ratio fse / fte of the optical lens within the range of 1 to 5, the value range of the zoom ratio of the optical lens is relatively wide, and the optical lens can simultaneously achieve shorter and longer focal lengths, which is beneficial to achieving shooting at the ultra-long focal length end and the long focal length end of the optical lens.

[0029] In a possible implementation, the optical lens satisfies: |ft × (1 / f123t - 1 / f12)| < 5, where f123t is the combined focal length of the first lens group, the second lens group, and the third lens group at the long focal length end of the optical lens.

[0030] It can be understood that the smaller the value of |ft × (1 / f123t - 1 / f12)|, the lower the focusing sensitivity of the optical lens, and the larger the value, the higher the focusing sensitivity of the optical lens. Thus, by restricting |ft × (1 / f123t - 1 / f12)| to be less than 5, the focusing of the optical lens can be accurately controlled, and the focusing effect of the optical lens can be improved.

[0031] In a possible implementation, the optical lens satisfies: |fs × (1 / f123s - 1 / f12)| < 5, where f123s is the combined focal length of the first lens group, the second lens group, and the third lens group at the ultra-long focal length end of the optical lens.

[0032] It can be understood that the smaller the value of |fs × (1 / f123s - 1 / f12)|, the lower the focusing sensitivity of the optical lens, and the larger the value, the higher the focusing sensitivity of the optical lens. Thus, by restricting |fs × (1 / f123s - 1 / f12)| to be less than 5, the focusing of the optical lens can be accurately controlled, and the focusing effect of the optical lens can be improved.

[0033] In a possible implementation, the optical lens satisfies: Redt > 0.15, where Redt is the magnification factor of the optical lens at the long focal length end in the macro state.

[0034] It can be understood that by restricting the magnification Redt of the telephoto end of the optical lens in the macro state to be within a range greater than 0.15, the magnification Redt of the telephoto end of the optical lens in the macro state is relatively large, which is conducive to achieving the shooting of the shooting object under macro by the optical lens.

[0035] In a possible implementation, the optical lens satisfies: Reds > 0.025, where Reds is the magnification of the ultra-telephoto end of the optical lens in the near state.

[0036] It can be understood that by restricting the magnification Reds of the ultra-telephoto end of the optical lens in the near state to be within a range greater than 0.025, the magnification Reds of the ultra-telephoto end of the optical lens in the near state is relatively large, which is conducive to achieving the shooting of the shooting object under near by the optical lens.

[0037] In a possible implementation, the optical lens satisfies: 0.15 < Redss < 1.0, where Redss is the magnification of the ultra-telephoto end of the optical lens in the macro state.

[0038] It can be understood that by restricting the magnification Redss of the ultra-telephoto end of the optical lens in the macro state to be within the range of 0.15 to 1.0, the magnification Redss of the ultra-telephoto end of the optical lens in the macro state is more appropriate, and the optical lens can achieve shooting with a larger magnification for a relatively far shooting object.

[0039] In a possible implementation, the material of the lens of the optical lens satisfies: 1.4 < Nd < 2.1, where Nd is the refractive index of the material.

[0040] It can be understood that by restricting the refractive index Nd of the material of each lens of the optical lens to be within the range of 1.4 to 2.1, the refractive index of each lens of the optical lens is smaller, the Abbe number is larger, and the light transmittance of each lens of the optical lens is higher. In this way, the light penetration of each lens of the optical lens is stronger, the optical quality of each lens of the optical lens is higher, and the image captured by the optical lens is clearer.

[0041] In a possible implementation, the material of the lens of the optical lens satisfies: 15 < Vd < 96, where Vd is the Abbe number.

[0042] It can be understood that by restricting the Abbe number Vd of each lens of the optical lens to be within the range of 15 to 96, the refractive index of each lens of the optical lens is smaller, the Abbe number is larger, and the light transmittance of each lens of the optical lens is higher. In this way, the light penetration of each lens of the optical lens is stronger, the optical quality of each lens of the optical lens is higher, and the image captured by the optical lens is clearer.

[0043] In a possible implementation, the optical lens satisfies: -5 < f2 / fs < 0, where f2 is the focal length of the second lens group.

[0044] It can be understood that the smaller the value of f2 / fs, the lower the sensitivity of the second lens group, and the larger the value, the higher the sensitivity of the second lens group. Thus, by restricting the ratio of the focal length f2 of the second lens group to the focal length fs of the ultra-telephoto end of the optical lens within the range of -5 to 0, the assembly tolerance between the first lens group and the fourth lens group is increased, and the loss of the resolution of the optical lens is reduced.

[0045] In a possible implementation, the optical lens satisfies: -8 < f1 / f2 < 0.

[0046] It can be understood that by restricting the ratio of the focal length f1 of the first lens group to the focal length f2 of the second lens group within the range of -8 to 0, the distribution of the focal length f1 of the first lens group and the focal length f2 of the second lens group is relatively reasonable. Under this distribution of the optical power, by reasonably setting the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance among aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be realized.

[0047] In a possible implementation, the first lens group includes one or more lenses and a folding element. At least one of the one or more lenses is located on the object side of the folding element, or the first lens group only includes the folding element, and the folding element has an optical power; the folding element is used to change the propagation direction of the optical axis from the first direction to the second direction.

[0048] It can be understood that the thickness of the optical lens in the first direction can be thinned. Thus, when the optical lens is applied to electronic devices such as mobile phones, the optical lens is not likely to increase the size of the electronic device in the thickness direction, which is beneficial to realizing the thin-type setting of the electronic device.

[0049] In a possible implementation, the material of one or more lenses is resin or glass.

[0050] It can be understood that when the material of one or more lenses of the first lens group is resin, the weight of the lens is small, which is beneficial to reducing the overall weight of the optical lens. In addition, one or more lenses of the first lens group have good resistance to vibration and impact. When the material of the lenses of the first lens group is glass, one or more lenses of the first lens group have excellent optical transparency, refractive index, and chemical stability, and are not easily scratched or deformed, which is beneficial to the optical lens to achieve clear and accurate imaging.

[0051] In a possible implementation, the deflection element is made of resin, glass or metal.

[0052] It is understood that when the deflecting element is made of resin, the deflecting element is lighter, which helps reduce the overall weight of the optical lens. In addition, resin has good processing properties and is less expensive to manufacture than glass.

[0053] When the material of the deflecting element is glass, the deflecting element has excellent optical properties, can reduce the optical distortion of the optical lens, and the deflecting element has good durability and stability, and can perform stably in various usage environments.

[0054] When the deflection element is made of metal, the deflection element can have higher mechanical strength and durability, and the metal can effectively conduct heat, so the deflection element is not prone to overheating during operation.

[0055] In a possible implementation, the second lens group includes one or more lenses, and the lens material of the second lens group is resin or glass.

[0056] It is understood that when the lenses of the second lens group are made of resin, the lenses of the second lens group are lighter, which helps reduce the overall weight of the optical lens. Furthermore, the lenses of the second lens group have better resistance to vibration and impact. When the lenses of the second lens group are made of glass, the lenses of the second lens group have excellent optical transparency, refractive index, and chemical stability, and are not easily scratched or deformed, which helps the optical lens achieve clear and accurate imaging.

[0057] In a possible implementation, the third lens group includes at least two lenses, and the lenses of the third lens group are made of resin or glass.

[0058] It is understood that when the lenses of the third lens group are made of resin, the lenses of the third lens group are lighter, which helps reduce the overall weight of the optical lens. Furthermore, the lenses of the third lens group have better resistance to vibration and impact. For example, when the lenses of the third lens group are made of glass, the lenses of the third lens group have excellent optical transparency, refractive index, and chemical stability, and are not easily scratched or deformed, which helps the optical lens achieve clear and accurate imaging.

[0059] In a possible implementation, the fourth lens group includes at least two lenses, and the lens material of the fourth lens group is resin or glass.

[0060] It is understood that when the lenses of the fourth lens group are made of resin, the lenses of the fourth lens group are lighter, which helps reduce the overall weight of the optical lens. Furthermore, the lenses of the fourth lens group have better resistance to vibration and impact. For example, when the lenses of the fourth lens group are made of glass, the lenses of the fourth lens group have excellent optical transparency, refractive index, and chemical stability, and are not easily scratched or deformed, which helps the optical lens achieve clear and accurate imaging.

[0061] In a possible implementation, the optical lens further includes a stop, and the stop is located between the second lens group and the third lens group, or the stop is located inside the second lens group or inside the third lens group.

[0062] It is understood that when the aperture is located between the second and third lens groups, or within the second or third lens groups, it can achieve a large aperture at both the telephoto and super-telephoto ends of the optical lens. Furthermore, when the aperture is located between the second and third lens groups, it facilitates correction of aperture aberrations. Furthermore, the optical lens of this embodiment utilizes a larger number of lenses for aberration correction, which facilitates achieving better imaging quality.

[0063] In one possible implementation, the optical lens further includes a light-converting element, which is located on the image side of the fourth lens group. The light-converting element is used to change the propagation direction of the optical axis from the second direction to a fourth direction, and the fourth direction is different from both the first direction and the second direction.

[0064] It can be understood that the light-redirecting element changes the propagation direction of the optical axis from the second direction to the fourth direction, which is beneficial to folding the light path and thus to miniaturizing the optical lens.

[0065] In a possible implementation, the light-redirecting element is an oblique prism, and the minimum acute angle α inside the light-redirecting element satisfies the following conditions: 17.5°≤a≤37.5°.

[0066] It is understood that the optical deflection element can bend the optical path, thereby increasing the optical length and improving the imaging quality of the optical lens. The optical deflection element can also compress the optical dimensions, reducing the size of the optical lens in the second direction, thereby facilitating a miniaturized optical lens configuration. The minimum acute angle α of the optical deflection element has an appropriate range of angle a, resulting in a suitable angle between the third direction and the second direction, which facilitates reducing the size of the optical lens in both the second and third directions, thereby facilitating a miniaturized optical lens configuration.

[0067] In a second aspect, the present application provides a camera module, which includes an image sensor and the aforementioned optical lens, wherein the image sensor is located on the image side of the optical lens.

[0068] It is understandable that the camera module can meet the requirements of miniaturization, high magnification ratio and high imaging performance while achieving continuous zoom and optical image stabilization at the same time.

[0069] In a third aspect, the present application provides an electronic device comprising an image processor and the aforementioned camera module, wherein the image processor is communicatively connected to the camera module and is configured to acquire image data from the camera module and process the image data.

[0070] It is understandable that electronic devices can meet the requirements of thin settings, high magnification ratio, and high imaging performance while achieving continuous zoom and optical image stabilization at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0137] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0138] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "install", "connect" and "connect" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the two components are connected to each other and the relative position relationship after connection remains unchanged. In addition, the two components are integrated into an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through further processing (such as bonding, welding, snap connection, screw connection).

[0139] The directional terms mentioned in the embodiments of the present application, such as "inside" and "outside", are only used to refer to the directions in the drawings. Therefore, the directional terms used are for better and clearer description and understanding of the embodiments of the present application, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0140] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship. "Multiple" means at least two.

[0141] To facilitate understanding of the optical lens and camera module provided in the embodiments of the present application, the following terms are explained:

[0142] Optical zoom refers to changing the focal length by physically moving the lens, thereby zooming in or out. Optical zoom is not prone to loss of image quality because it changes the physical structure of the lens.

[0143] Focusing refers to adjusting the lens position to ensure a clear image of the subject without changing the focal length of the system.

[0144] The optical axis is an axis passing through the center of each lens.

[0145] With the lens as the boundary, the side where the object is located is called the object side, and the surface of the lens close to the object side is called the object side surface.

[0146] With the lens as the boundary, the side where the image of the object is located is called the image side, and the surface of the lens close to the image side is called the image side surface.

[0147] Focal length, also known as focal length, is a measure of the convergence or divergence of light in an optical system. It refers to the vertical distance from the optical center of a lens or optical component to the focal plane, when an infinitely distant object is formed into a sharp image on the focal plane. From a practical perspective, it can be understood as the distance from the center of the lens to the image plane. For fixed-focus lenses, the position of the optical center is fixed.

[0148] The focal length of an optical lens is defined as the distance from the center of the optical lens to the focal point.

[0149] Focal power, defined as the difference between the image-side beam convergence and the object-side beam convergence, is the reciprocal of the focal length of the lens and characterizes the ability of an optical system to deflect light.

[0150] Positive optical power, also called positive refractive power, means that the lens has a positive focal length and can focus light.

[0151] Negative optical power, also known as negative refractive power, means that the lens has a negative focal length and can diverge light.

[0152] Telephoto end (te l escop icend), the longer focal length section of the lens, the lens angle of view is smaller, used for shooting distant scenes, especially local close-ups.

[0153] The focal length of the telephoto end of the camera module (focal length that is telephoto, ft) is defined as the distance from the center of the telephoto end of the camera module to the focal point.

[0154] Super telephoto end (supertelephoto end) is the longest focal length of the lens and has the smallest viewing angle. It is used to shoot distant scenes, especially close-ups.

[0155] The focal length at the super telephoto end of the camera module (fs) is defined as the distance from the center to the focus of the super telephoto end of the camera module.

[0156] The middle section of the camera module is defined as the middle state between the telephoto end and the super telephoto end.

[0157] The focal length of the middle section of the camera module (fm) is defined as the distance from the center of the middle section of the camera module to the focus.

[0158] The image height (Imaging Height, IH) of the imaging surface represents half of the diagonal length of the effective pixel area on the photosensitive chip, that is, the radius of the imaging circle.

[0159] The refractive index (Nd) of a material is defined as the absolute value of the ratio of the propagation speed of electromagnetic waves (including visible light) to the speed of light in a vacuum when the material propagates. It is an indicator that describes the propagation speed and bending degree of the material to light.

[0160] The Abbe number (Vd), also known as the dispersion coefficient, is the difference ratio of the refractive index of an optical material at different wavelengths, representing the degree of dispersion of the material.

[0161] An aperture is an entity that limits the light beam in an optical system. It can be the edge of a lens, a frame, or a specially designed screen with holes. Its function can be divided into two aspects: limiting the light beam or limiting the field of view (imaging range). The aperture that most limits the light beam in an optical system is called the aperture stop; the aperture that most limits the field of view (size) is called the field stop.

[0162] Aberration: The paraxial region of an optical system has the properties of an ideal optical system. The paraxial light emitted from a point on the object intersects the image plane at one point (also known as the paraxial image point). However, the light rays that actually pass through different apertures of the lens are unlikely to intersect perfectly at one point. Instead, there is a certain deviation from the position of the paraxial image point. These differences are collectively called aberrations.

[0163] Axial chromatic aberration, also known as longitudinal chromatic aberration, positional chromatic aberration, or axial chromatic aberration, occurs when a beam of light parallel to the optical axis converges at different positions before and after passing through a lens. This is due to the lens imaging different wavelengths of light at different positions, resulting in the different focal planes of the different colors of light not coinciding with each other in the final image, causing the complex colors of light to scatter and form dispersion.

[0164] Distortion, also known as distortion, refers to the degree to which the image formed by an optical system is distorted relative to the object itself. Distortion is caused by spherical aberration. The height of the intersection of the chief rays of light from different fields of view with the Gaussian image plane after passing through the optical system is not equal to the ideal image height. The difference between the two is the distortion. Therefore, distortion only changes the image position of off-axis object points on the ideal plane, distorting the image shape but not affecting image clarity.

[0165] Astigmatism (astigmatism) occurs when the object point is not on the optical axis of an optical system. The light beam emitted by the object is tilted at an angle to the optical axis. After refraction through a lens, the convergence points of the meridional and sagittal beamlets are not the same. This means the beam cannot be focused to a single point, resulting in an unclear image. Meridional and sagittal beamlets are the names for beams occurring in two perpendicular planes within a rotationally symmetric optical system.

[0166] Meridian plane (meridian plane), the plane formed by the chief ray (chief light beam) of an object point outside the optical axis and the optical axis is called the meridian plane.

[0167] The sagittal plane is the plane that passes through the main ray (main beam) of the object point outside the optical axis and is perpendicular to the meridian plane.

[0168] Field curvature is used to describe the difference in the optical axis between the sharpest image point of non-central field light after passing through an optical lens system and the sharpest image point of the central field light. When a lens has field curvature, the intersection of the entire light beam does not coincide with the ideal image point. Although a sharp image point can be obtained at each specific point, the entire image plane is a curved surface.

[0169] Figure 1A It is a structural diagram of an electronic device 1000 provided in an embodiment of the present application in one implementation manner.

[0170] like Figure 1AAs shown, in some embodiments, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet, or other devices with photo and video recording functions. Figure 1A The electronic device 1000 in the illustrated embodiment is described by taking a mobile phone as an example.

[0171] Figure 1B yes Figure 1A The electronic device 1000 is shown as a partial cross-sectional schematic diagram of an embodiment at line AA.

[0172] like Figure 1B As shown, the electronic device 1000 includes a screen 100, a housing 200, a camera module 300, an image processor 400, and an analog-to-digital converter 500. In other embodiments, the electronic device 1000 may include more or fewer structures. For example, when the electronic device 1000 includes more structures, the electronic device 1000 may also include a circuit board (not shown in the drawings). When the electronic device 1000 includes fewer structures, the electronic device 1000 may not include the screen 100. It is understandable that Figure 1A and Figure 1B Only some components of the electronic device 1000 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1A and Figure 1B limited.

[0173] For example, screen 100 can be fixed to housing 200 and used to display images to meet user needs. The display layer can be a liquid crystal display or an organic light-emitting diode display. Together with housing 200, screen 100 and housing 200 can enclose the interior of electronic device 1000. The interior of electronic device 1000 can be used to house components of electronic device 1000, such as a battery, receiver, or microphone. Screen 100 can be either flat or curved.

[0174] For example, the camera module 300 can be installed in the housing 200 , and the light incident side of the camera module 300 can be set to face away from the screen 100 to serve as a rear camera of the electronic device 1000 .

[0175] For example, the housing 200 may have a light-transmitting portion 201. The shape of the light-transmitting portion 201 is not limited to the shape of the light-transmitting portion 201. Figure 1A The circular shape shown may also be an elliptical or irregular shape. The light-transmitting portion 201 connects the interior of the electronic device 1000 to the exterior of the electronic device 1000. Light from outside the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201, and the light-transmitting portion 201 is dustproof and waterproof. The camera module 300 can collect light from outside the electronic device 1000 through the light-transmitting portion 201 to capture images or videos.

[0176] In other embodiments, the light incident side of the camera module 300 can face the side where the screen 100 is located, serving as a front-facing transparent camera of the electronic device 1000. Both the front camera and the rear camera can be used for selfies or for the photographer to take pictures of other objects.

[0177] It is understandable that Figure 1A The installation location of the camera module 300 of the electronic device 1000 in the illustrated embodiment is merely illustrative, and this application does not impose strict limitations on the installation location of the camera module 300. In some other embodiments, the camera module 300 may also be installed in other locations of the electronic device 1000, for example, the camera module 300 may be installed in the upper middle portion or the upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can be rotated, moved, or removed relative to the terminal body, and the camera module 300 may also be disposed on the auxiliary component.

[0178] For example, the image processor 400 can be communicatively connected to the camera module 300. The image processor 400 can be used to obtain image data from the camera module 300 and process the image data. The communication connection between the camera module 300 and the image processor 400 can include data transmission via electrical connections such as wiring, or data transmission can be achieved through coupling or other methods. It is understood that the camera module 300 and the image processor 400 can also be communicatively connected via other methods that can achieve data transmission.

[0179] Image processor 400 may include multiple processing modules that convert the raw image signal captured by camera module 300 to form image information, transmit the processed information to the display module of the display screen, and display the image or video on the display screen. Image processor 400 may be an image processing chip or a digital signal processing chip, and is used to adjust image color, perform noise reduction processing on the image, and further improve image quality.

[0180] In the embodiment of the present application, the operating principle of the camera module 300 in the electronic device 1000 may be as follows: light reflected from the captured scene enters the interior of the camera module 300, generating an optical image that is projected onto the surface of the image sensor of the camera module 300. The image sensor converts the optical image into an electrical signal, i.e., an analog image signal, and transmits the converted analog image signal to the analog-to-digital converter 500. The analog-to-digital converter 500 converts the converted analog image signal into a digital image signal that is then transmitted to the image processor 400. The image processor 400 may operate to convert the raw image signal captured by the camera module 300 to form image information, and transmit the processed information to the screen 100 for displaying the image or video on the screen 100. In other embodiments, the electronic device 1000 may further include a memory (not shown in the drawings). The image processor 400 may process the digital image signal and transmit the image to the memory so that the image can be retrieved from the memory and displayed on the screen 100 at any time when the image is needed.

[0181] Figure 1A It is just a schematic diagram showing the structure of an electronic device 1000. Figure 1A The size, quantity and position of the camera module 300, image processor 400 and analog-to-digital converter 500 shown are only schematic representations and can be adjusted as needed. This application does not limit this.

[0182] It is understood that the number of camera modules 300 can be one or at least two. When the number of camera modules 300 is one, the camera module 300 can be used as a front camera or a rear camera. When the number of camera modules 300 is at least two, the at least two camera modules 300 can be a telephoto camera module 300, an ultra-telephoto camera module 300, or other cameras that can meet different shooting requirements, and this application does not limit this.

[0183] Figure 2A yes Figure 1A The illustrated diagram is a structural diagram of an operation interface of an electronic device 1000 in one embodiment.

[0184] like Figure 1A and Figure 2AAs shown, when the user of electronic device 1000 is using electronic device 1000 to take a photo, camera module 300, image processor 400, and analog-to-digital converter 500 are in operation. Light reflected by the object being photographed is sequentially captured by camera module 300, converted by analog-to-digital converter 500, and converted by image processor 400 to form image information, which is then displayed on screen 100. In other embodiments, the shooting operation interface of electronic device 1000 may also be in other forms. This application does not limit this in detail.

[0185] For example, the user can operate on the screen 100 to issue an operating instruction to the electronic device 1000, thereby changing the zoom ratio of the camera module 300. The zoom ratio of the camera module 300 can range from 1x (also referred to as 1x) to 10x (also referred to as 10x). It is understandable that the camera module 300 can continuously zoom from 1x to 10x, or from 10x to 1x. In other words, during the continuous zoom process of the camera module 300, the zoom ratio of the camera module 300 can be any value between 1x and 10x. For example, the zoom ratio of the camera module 300 can be 1x, 1.8x, 2.3x, 3x, 3.5x, 4x, 5x, 5.3x, 6x, 7.65x, 8x, 9.5x or 10x, etc.

[0186] For example, when the camera module 300 is at the telephoto end, the zoom ratio of the camera module 300 may be 3 times; when the camera module 300 is at the super telephoto end, the zoom ratio of the camera module 300 may be 10 times.

[0187] For example, when the camera module 300 zooms from the telephoto end to the super telephoto end, the zoom magnification of the camera module 300 changes continuously. For example, when the camera module 300 is in an intermediate state between the telephoto end and the super telephoto end, the zoom magnification of the camera module 300 can be any value between 3x and 10x. For example, the zoom magnification of the camera module 300 can be 3.2x, 4x, 4.3x, 5.1x, 5.5x, 6x, 6.3x, 6.9x, 7x, 7.8x, 8x, 9x, or 9.89x. It will be understood that when the camera module 300 zooms from the super telephoto end to the telephoto end, the zoom magnification of the camera module 300 also changes continuously, and the zoom magnification of the camera module 300 can be any value between 10x and 3x.

[0188] It can be understood that in the process of zooming the camera module 300 from the telephoto end to the super telephoto end or from the super telephoto end to the telephoto end, the camera module 300 can achieve continuous zoom within the zoom range. Compared with the jump zoom solution, the imaging clarity of the camera module 300 is better and the imaging quality of the camera module 300 is higher.

[0189] In other embodiments, when the camera module 300 is at the telephoto end, the zoom magnification of the camera module 300 may also be other values, for example, the zoom magnification of the camera module 300 at the telephoto end is 6x. When the camera module 300 is at the super telephoto end, the zoom magnification of the camera module 300 may also be other values, for example, the zoom magnification of the camera module 300 at the super telephoto end is 10x. Furthermore, when the camera module 300 is in a state intermediate between the telephoto end and the super telephoto end, the zoom magnification of the camera module 300 may be any value between 6x and 10x. This application does not impose any specific limitations.

[0190] like Figure 1B As shown, for example, the camera module 300 may include an optical lens 10, an image sensor 20, and a filter 30. The light reflected from the scene being photographed is refracted by the optical lens 10, passes through the filter 30, and is incident on the image sensor 20 for imaging. It is understood that Figure 1B The following figures and the related drawings only schematically illustrate some components of the camera module 300, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1B As defined in the accompanying drawings below. It is understood that the camera module 300 may include fewer or more structures. For example, the camera module 300 may include fewer structures. For example, the camera module 300 may not include the filter 30. The camera module 300 may include more structures, for example, the camera module 300 may also include a lens holder (not shown in the drawings).

[0191] The image sensor 20 can be located on the image side of the optical lens 10. The image sensor 20 is a semiconductor chip, also known as a photosensitive chip. The surface of the image sensor 20 contains hundreds of thousands to millions of photodiodes, which generate an electrical charge when exposed to light. The image sensor 20 utilizes the photoelectric conversion function of a photoelectric device to convert the light image on its photosensitive surface into an electrical signal proportional to the light image. The photosensitive surface of the image sensor 20 can be positioned facing the optical lens 10. The image sensor 20 can be a charge-coupled device, a complementary metal oxide semiconductor, a phototransistor, or a thin-film transistor, among others.

[0192] For example, the filter 30 can be located between the optical lens 10 and the image sensor 20. Light passing through the optical lens 10 is incident on the filter 30 and filtered by the filter 30 to form an image on the image sensor 20. For example, the filter 30 can be an infrared filter 30. The filter 30 can eliminate light of unnecessary wavelengths projected onto the image sensor 20, preventing the image sensor 20 from generating false colors or ripples, thereby improving its effective resolution and color reproduction. This application does not strictly limit the specific embodiments of the structural components or structures used to implement filtering.

[0193] In some embodiments, the camera module 300 may also eliminate the filter 30 and instead implement light filtering by performing surface treatment or material treatment on at least one optical element of the optical lens 10. This application does not strictly limit the specific embodiments of the structural components or structures used to implement light filtering.

[0194] The following Figure 1B The implementation scheme of the optical lens 10 in the camera module 300 is illustrated as an example.

[0195] like Figure 1B As shown, the optical lens 10 includes a first lens group G1, a second lens group G2, a third lens group G3, and a fourth lens group G4 arranged in sequence from the object side to the image side. The first lens group G1 is used to change the propagation direction of the optical axis from a first direction to a second direction. The second direction is different from the first direction.

[0196] For example, the first direction may be the Z-axis direction. The second direction may be the X-axis direction. For example, the Z-axis direction may be the thickness direction of the electronic device 1000. The X-axis direction may be the width direction of the electronic device 1000. In other embodiments, the first direction and the second direction are not specifically limited.

[0197] It is understandable that Figure 1B The following figures and the related drawings only schematically illustrate some components of the optical lens 10. The actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1B As defined in the accompanying drawings below. It is understood that the optical lens 10 may also include fewer or more structures. For example, the optical lens 10 may include more structures, such as the optical lens 10 may also include a lens holder (not shown in the accompanying drawings).

[0198] For example, the first lens group G1 may include one or more lenses and a deflecting element 1a, with at least one of the one or more lenses located on the object side of the deflecting element 1a. The deflecting element 1a may be configured to change the direction of propagation of the optical axis from a first direction to a second direction. During zooming of the optical lens system 10, the first lens group G1 may be a fixed lens group.

[0199] For example, the deflecting element 1a may be a prism, a reflector, or other components with a reflective function. The incident surface and the exit surface of the deflecting element 1a may be optical surfaces such as a plane, a spherical surface, or an aspherical surface. This application does not limit this in detail.

[0200] In other embodiments, the first lens group G1 may not include one or more lenses. In this case, the first lens group G1 only includes the folding element 1 a.

[0201] For example, the second lens group G2 may include one or more lenses. During the zooming process of the optical lens 10, the second lens group G2 may be a fixed lens group. In other embodiments, during the zooming process of the optical lens 10, the second lens group G2 may also move along the optical axis of the second direction.

[0202] For example, the third lens group G3 may include at least two lenses. During the zooming process of the optical lens system 10, the third lens group G3 may move along the optical axis in the second direction. In this way, the optical lens system 10 can achieve continuous zooming. In other embodiments, the third lens group G3 may also include a single lens. During the zooming process of the optical lens system 10, the third lens group G3 may also be a fixed lens group.

[0203] Illustratively, the fourth lens group G4 may include at least two lenses. During the zooming process of the optical lens system 10, the fourth lens group G4 may move along the optical axis in the second direction. In this way, the optical lens system 10 can achieve continuous zooming. In other embodiments, the fourth lens group G4 may also include a single lens. During the zooming process of the optical lens system 10, the fourth lens group G4 may also be a fixed lens group.

[0204] It is understood that because the third lens group G3 and the fourth lens group G4 can move along the optical axis in the second direction, the optical lens 10 can achieve continuous zoom. In addition, the third lens group G3 and the fourth lens group G4 are unlikely to occupy too much space in the first direction, thereby reducing the length of the optical lens 10 in the first direction, improving the space utilization of the optical lens 10, and thus facilitating the miniaturization of the optical lens 10. When the optical lens 10 is applied to the electronic device 1000, the electronic device 1000 can achieve continuous zoom, and the size of the optical lens 10 in the thickness direction of the electronic device 1000 is small, thereby facilitating the thinning of the electronic device 1000.

[0205] Exemplarily, the camera module 300 may include a driving mechanism (not shown in the accompanying drawings), which may be connected to the third lens group G3 and the fourth lens group G4, and the driving mechanism may be used to drive the third lens group G3 and the fourth lens group G4 to move along the optical axis in the second direction. It is understandable that the number of driving mechanisms may also be two, one driving mechanism drives the third lens group G3 to move along the optical axis in the second direction, and the other driving mechanism drives the fourth lens group G4 to move along the optical axis in the second direction. In other embodiments, the number of driving mechanisms may be one, and the driving mechanism is an integrated, integral driving device, which may simultaneously drive the third lens group G3 and the fourth lens group G4 to move along the optical axis in the second direction. The driving mechanism may be a motor, for example, the driving mechanism may be a voice coil motor or a shape memory alloy motor.

[0206] For example, the first lens group G1 may have positive refractive power, the second lens group G2 may have negative refractive power, the third lens group G3 may have positive refractive power, and the fourth lens group G4 may have negative refractive power.

[0207] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0208] It can be understood that the first lens group G1 has positive optical focal length, and the first lens group G1 can play the role of shrinking light; the second lens group G2 has negative optical focal length, and the second lens group G2 can play the role of diverging light, and the second lens group G2 diverges the light so that the field of view angle of the group becomes smaller; the third lens group G3 and the fourth lens group G4 can cooperate to achieve focusing and zooming of the optical lens 10 and the camera module 300, thereby improving the imaging quality of the optical lens 10 and the camera module 300.

[0209] It can be understood that, based on the fact that the optical lens 10 can simultaneously achieve optical image stabilization and continuous zoom, the optical power configuration of the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 can be reasonably used, and the coordination of specific optical lenses with other parameters, such as aspheric surface, focal length, refractive index, total optical length of the optical lens 10, axial thickness and curvature radius, can be reasonably used to enable the optical lens 10 to meet the requirements of high zoom ratio and continuous zoom while achieving high imaging performance.

[0210] In other embodiments, the optical power of the first lens group G1, the optical power of the second lens group G2, the optical power of the third lens group G3, and the optical power of the fourth lens group G4 may be configured in other ways, which are not specifically limited in this application.

[0211] In some embodiments, the deflecting element 1a may not have optical power. For example, when the deflecting element 1a does not have optical power, the first lens group may further include one or more lenses, and one or more lenses of the first lens group G1 may be located on the object side of the deflecting element 1a. In this case, the first lens group G1 consists of one or more lenses and the deflecting element 1a.

[0212] In some embodiments, the deflecting element 1a may have optical power. It is understood that the deflecting element 1a having optical power can reduce the number of lenses in the first lens group G1, simplify the structural complexity of the first lens group G1, and thus simplify the structural complexity of the optical lens 10 and the camera module 300. Exemplarily, when the deflecting element 1a has optical power, the first lens group G1 is composed of one or more lenses and the deflecting element 1a. In other embodiments, the first lens group G1 may not include one or more lenses. In this case, the first lens group G1 is composed of the deflecting element 1a.

[0213] For example, the first lens group G1 may have an anti-shake compensation function. For example, during the optical image stabilization process of the optical lens 10, the first lens group G1 may rotate about the first direction, or about the second direction, or about the third direction, or about the first direction and the second direction, or about the second direction and the third direction, or about the first direction and the third direction, or about the first direction, the second direction, and the third direction, to achieve optical image stabilization of the optical lens 10 and improve the imaging quality of the optical lens 10. The third direction may be different from both the first direction and the second direction.

[0214] Exemplarily, the third direction may be located in a plane formed by the first direction and the second direction (ie, an XZ plane).

[0215] For example, the third direction may be perpendicular to the plane formed by the first direction and the second direction. The third direction may be the Y-axis direction. For example, the Y-axis direction may be the length direction of the electronic device 1000.

[0216] It is understandable that the optical lens 10 can achieve continuous zoom and optical image stabilization at the same time.

[0217] Figure 2B yes Figure 1B The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment.

[0218] like Figure 2B As shown, illustratively, the first lens group G1 may have a first rotation axis O1 and a first rotation center P1.

[0219] For example, the direction of the first rotation axis O1 can be parallel to the first direction. The first rotation axis O1 can pass through the deflection element 1a or can be located outside the deflection element 1a. It is understood that Figure 2B The first rotation axis O1 is only schematically shown as a straight line passing through the deflection element 1a, and the specific position of the first rotation axis O1 is not affected by Figure 2B Position limitation in .

[0220] For example, the first rotation center P1 can be located at any position on the first rotation axis O1. The first rotation center P1 can be located inside the deflection element 1a and at the intersection of the first rotation axis O1 and the deflection element 1a, or at any other position inside the deflection element 1a, or outside the deflection element 1a. It is understood that Figure 2B The first rotation center P1 is only schematically shown to be located inside the deflection element 1a and at the intersection of the first rotation axis O1 and the deflection element 1a. The specific position of the first rotation center P1 is not affected by the above. Figure 2B Position limitation in .

[0221] It is understandable that the first lens group G1 can rotate around the first rotation axis O1 with the first rotation center P1 as the rotation center to achieve optical image stabilization of the optical lens 10 and the camera module 300, thereby improving the imaging quality of the optical lens 10 and the camera module 300.

[0222] like Figure 2B As shown, illustratively, the first lens group G1 may have a second rotation axis O2 and a second rotation center P2.

[0223] For example, the direction of the second rotation axis O2 can be parallel to the second direction, and the second rotation axis O2 can intersect with the first rotation axis O1. The second rotation axis O2 can pass through the deflection element 1a or can be located outside the deflection element 1a. It is understood that Figure 2B The second rotation axis O2 is only schematically shown as a straight line passing through the deflection element 1a, and the specific position of the second rotation axis O2 is not affected by Figure 2B Position limitation in .

[0224] For example, the second rotation center P2 can be located at any position on the second rotation axis O2, and the second rotation center P2 can coincide with the first rotation center P1. The second rotation center P2 can be located inside the deflection element 1a and at the intersection of the second rotation axis O2 and the deflection element 1a, or at any other position inside the deflection element 1a, or outside the deflection element 1a. It is understood that Figure 2BThe second rotation center P2 is only schematically shown to be located inside the deflection element 1a and at the intersection of the second rotation axis O2 and the deflection element 1a. The specific position of the second rotation center P2 is not affected by Figure 2B Position limitation in .

[0225] It can be understood that the first lens group G1 can rotate around the second rotation axis O2 with the second rotation center P2 as the rotation center to achieve optical image stabilization of the optical lens 10 and the camera module 300, thereby improving the imaging quality of the optical lens 10 and the camera module 300.

[0226] like Figure 2B As shown, for example, the first lens group G1 can further rotate about a third direction. The third direction can be any direction on the plane formed by the first and second directions (i.e., the XZ plane), or a direction perpendicular to the plane formed by the first and second directions. This application does not limit this in detail.

[0227] Illustratively, the first lens group G1 may have a third rotation axis O3 and a third rotation center P3.

[0228] For example, the direction of the third rotation axis O3 can be parallel to the third direction. The third rotation axis O3 can intersect with the first rotation axis O1 and the second rotation axis O2 but not perpendicular to them, or can intersect with and be perpendicular to the first rotation axis O1 and the second rotation axis O2, or can be parallel to the first rotation axis O1 or the second rotation axis O2. The third rotation axis O3 can pass through the deflection element 1a or can be located outside the deflection element 1a. It is understandable that Figure 2B The third rotation axis O3 is only schematically shown as a straight line passing through the deflection element 1a, and intersecting and perpendicular to the first rotation axis O1 and the second rotation axis O2. The specific position of the third rotation axis O3 is not affected by the Figure 2B Position limitation in .

[0229] For example, the third rotation center P3 can be located at any position on the third rotation axis O3, can be located inside the deflection element 1a and at the intersection of the third rotation axis O3 and the deflection element 1a, can be located at any other position inside the deflection element 1a, or can be located outside the deflection element 1a. It is understandable that Figure 2B The third rotation center P3 is only schematically shown to be located outside the deflection element 1a, and the specific position of the third rotation center P3 is not affected by the present invention. Figure 2B limited.

[0230] It can be understood that the first lens group G1 can rotate around the third rotation axis O3 with the third rotation center P3 as the rotation center to achieve optical image stabilization of the optical lens 10 and the camera module 300, thereby improving the imaging quality of the optical lens 10 and the camera module 300.

[0231] like Figure 2B As shown, for example, when the third direction is perpendicular to the plane formed by the first and second directions, the distance between the intersection of the first and second directions and the third direction is d, and d satisfies: 0 < d ≤ 10 mm (millimeter). For example, d can be equal to 0.5 mm, 1 mm, 1.4 mm, 2.8 mm, 3.3 mm, 4.8 mm, 5 mm, 6.67 mm, 7 mm, 8.88 mm, 9.5 mm, or 10 mm. It can be understood that when the first lens group G1 rotates about this third direction, the optical image stabilization effect of the optical lens system 10 is better.

[0232] In some embodiments, d satisfies: 0<d≤7mm, for example, d can be equal to 0.1mm, 1mm, 2.6mm, 3mm, 4.1mm, 5.35mm, 6.6mm or 7mm. It can be understood that when the first lens group G1 rotates about the third direction, the optical image stabilization effect of the optical lens 10 is better.

[0233] In other embodiments, the distance d between the intersection of the first direction and the second direction and the third direction may also meet other ranges, which are not specifically limited in this application.

[0234] For example, the anti-shake drive mechanism may also be connected to the first lens group G1, and the anti-shake drive mechanism may be used to drive the first lens group G1 to move, thereby achieving optical image stabilization of the optical lens 10. In other embodiments, the anti-shake drive mechanism of the first lens group G1, the drive mechanism of the third lens group G3, and the drive mechanism of the fourth lens group G4 may be integrated into a single drive mechanism. The designs of the anti-shake drive mechanism of the first lens group G1, the drive mechanism of the third lens group G3, and the drive mechanism of the fourth lens group G4 may be flexibly adjusted according to actual needs and are not specifically limited in this application.

[0235] Figure 3A yes Figure 1B The camera module 300 shown is a simplified schematic diagram of part of the structure in one embodiment. Figure 3B yes Figure 3A The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 3C yes Figure 3B The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figures 3A to 3CThe camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0236] like Figures 3A to 3C As shown, illustratively, the second direction includes a first sub-direction and a second sub-direction in opposite directions. The first sub-direction can be the direction from the third lens group G3 to the second lens group G2, and the second sub-direction can be the direction from the second lens group G2 to the third lens group G3. In other words, the first sub-direction can be the negative direction of the X-axis. The second sub-direction can be the positive direction of the X-axis. In other embodiments, the first sub-direction can also be the direction from the second lens group G2 to the third lens group G3, and the second sub-direction can also be the direction from the third lens group G3 to the second lens group G2. In other words, the first sub-direction can be the positive direction of the X-axis. The second sub-direction can be the negative direction of the X-axis. It is understood that the first sub-direction and the second sub-direction can be flexibly set according to actual needs, and this application does not specifically limit them.

[0237] like Figures 3A to 3C As shown, for example, during the zooming process of the optical lens 10 from the telephoto end to the super-telephoto end, the first lens group G1 and the second lens group G2 are both fixed lens groups, while the third lens group G3 and the fourth lens group G4 can move along the optical axis in the first sub-direction. At this time, the distance between the second lens group G2 and the third lens group G3 decreases. When the optical lens 10 is at the super-telephoto end, the optical lens 10 can focus on distant subjects (including the user using the optical lens 10).

[0238] like Figures 3A to 3C As shown, for example, during the zooming process of the optical lens 10 from the super-telephoto end to the telephoto end, the first lens group G1 and the second lens group G2 are both fixed lens groups, while the third lens group G3 and the fourth lens group G4 can move along the optical axis in the second sub-direction. At this time, the distance between the second lens group G2 and the third lens group G3 increases. When the optical lens 10 is at the telephoto end, the optical lens 10 can focus on close-up or even macro subjects (including the user using the optical lens 10).

[0239] It is understood that because the third lens group G3 and the fourth lens group G4 can move along the optical axis of the first sub-direction or the optical axis of the second sub-direction, the optical lens 10 can achieve continuous zoom. In addition, the third lens group G3 and the fourth lens group G4 are unlikely to occupy too much space in the first direction, thereby reducing the length of the optical lens 10 in the first direction, improving the space utilization of the optical lens 10, and thus facilitating the miniaturization of the optical lens 10. When the optical lens 10 is applied to the electronic device 1000, the electronic device 1000 can achieve continuous zoom, and the size of the optical lens 10 in the thickness direction of the electronic device 1000 is small, thereby facilitating the thinning of the electronic device 1000.

[0240] like Figure 1B As shown, the optical lens 10 may further include a stop 5. Exemplarily, the stop 5 may be located between every two lenses.

[0241] For example, the aperture 5 may be an aperture aperture, which is used to limit the amount of light entering the optical lens 10 and reduce stray light in the optical lens 10 to change the brightness of the image. In other embodiments, the position of the aperture 5 is not limited to Figure 1B The illustrated aperture 5 is located between the second lens group G2 and the third lens group G3. The aperture 5 can also be located inside the second lens group G2 or inside the third lens group G3. The position of the aperture 5 can be flexibly adjusted according to actual needs.

[0242] It will be appreciated that when the diaphragm 5 is located between the second lens group G2 and the third lens group G3, or when the diaphragm 5 is located within the second lens group G2 or within the third lens group G3, the diaphragm 5 can achieve a large aperture at both the telephoto and super-telephoto ends of the optical lens 10. Furthermore, when the diaphragm 5 is located between the second lens group G2 and the third lens group G3, aberration correction of the diaphragm 5 is facilitated. Furthermore, the optical lens 10 of this embodiment utilizes a relatively large number of lenses for aberration correction, which facilitates achieving superior imaging quality.

[0243] In other embodiments, the optical lens 10 may not include the aperture 5. It is understood that Figure 1B Only some components of the optical lens 10 are schematically shown, and the actual shapes, actual sizes and actual structures of these components are not subject to Figure 1B limited.

[0244] Some specific but non-limiting examples of the embodiments of the present application will be described in more detail below with reference to the relevant drawings.

[0245] The first implementation method: Figure 4A yes Figure 3CThe illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 4B yes Figure 4A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figure 4A and Figure 4B The camera module 300 is in the close-range state at the super-telephoto end and the macro state at the super-telephoto end respectively.

[0246] like Figure 3C and Figure 4A As shown, for example, during zooming of the camera module 300 from the ultra-telephoto end to the ultra-telephoto end at close range, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, while the third lens group G3 can move along the optical axis in the first sub-direction. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0247] In some embodiments, during the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0248] like Figure 4A and Figure 4B As shown, for example, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis in the second sub-direction. In this case, the distance between the fourth lens group G4 and the third lens group G3 is further increased.

[0249] In some embodiments, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0250] Figure 5 yes Figure 3A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in another embodiment. It can be understood that Figure 5 The camera module 300 is in the macro state at the telephoto end.

[0251] like Figure 3A and Figure 5 As shown, for example, during zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, while the third lens group G3 can move along the optical axis of the first sub-direction. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0252] In some embodiments, during the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. This application does not limit this specifically.

[0253] The structure of the optical lens 10 is described in detail above with reference to the relevant drawings. The following description will describe in detail the settings of the relevant optical parameters of the optical lens 10 with reference to the drawings.

[0254] Exemplarily, the optical lens 10 can satisfy: 0.2<|ΔG4 / ΔG3|<5, where ΔG3 is the distance that the third lens group G3 moves along the optical axis in the second direction, ΔG4 is the distance that the fourth lens group G4 moves along the optical axis in the second direction, and |ΔG4 / ΔG3| can be equal to 0.21, 0.5, 1, 1.8, 2.3, 3.55, 4.26 or 4.99, etc.

[0255] It can be understood that by limiting the absolute value of the ratio of the distance ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction to the distance ΔG3 of the third lens group G3 moving along the optical axis in the second direction within the range of 0.2 to 5, the respective moving strokes of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the stroke when the driving mechanism drives the third lens group G3 and the fourth lens group G4 to move is smaller, which is conducive to the miniaturization of the optical lens 10. At the same time, the structure of the driving mechanism is simpler and more user-friendly.

[0256] In other embodiments, the ratio |ΔG4 / ΔG3| of the distance ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction to the distance ΔG3 of the third lens group G3 moving along the optical axis in the second direction may also satisfy other ranges, which is not specifically limited in this application.

[0257] It will be understood that, for ease of describing the movement directions of the third lens group G3 and the fourth lens group G4, the following text defines that the third lens group G3 and the fourth lens group G4 move toward the object side along the optical axis of the second direction, that is, when the third lens group G3 and the fourth lens group G4 move along the optical axis of the first sub-direction, ΔG3 satisfies: ΔG3>0, and ΔG4 satisfies: ΔG4>0. When the third lens group G3 and the fourth lens group G4 move toward the image side along the optical axis of the second direction, that is, when the third lens group G3 and the fourth lens group G4 move along the optical axis of the second sub-direction, ΔG3 satisfies: ΔG3<0, and ΔG4 satisfies: ΔG4<0. In other embodiments, the positive and negative values ​​of ΔG3 and ΔG4 can be flexibly set according to specific practical needs.

[0258] Exemplarily, the optical lens 10 can satisfy: |(ΔG3 + ΔG4) / fs| < 5. For example, |(ΔG3 + ΔG4) / fs| can be equal to 0.5, 1, 1.8, 2.3, 3, 3.6, 4.2, or 4.9, etc. It can be understood that the smaller the value of |(ΔG3 + ΔG4) / fs|, compared with the solution of the same focal length of the optical lens 10, the distances ΔG3 of the third lens group G3 moving along the optical axis in the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction of the present application can both be smaller; compared with the solution of the distances ΔG of the third lens group G3 moving along the optical axis in the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction of the same third lens group G3, the focal length of the optical lens 10 of the present application can be larger. Thus, by restricting |(ΔG3 + ΔG4) / fs| within a range less than 5, reducing the distance ΔG3 of the third lens group G3 moving along the optical axis in the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction, or increasing the corresponding focal length of the optical lens 10, is beneficial to achieving the miniaturized setting of the optical lens 10.

[0259] In other embodiments, |(ΔG3 + ΔG4) / fs| can also satisfy other ranges. Specifically, the present application does not make any limitations.

[0260] Exemplarily, the optical lens 10 can satisfy: 0.2 < ft / fs < 0.8, where ft is the focal length of the telephoto end of the optical lens 10, fs is the focal length of the ultra-telephoto end of the optical lens 10, and ft / fs can be equal to 0.21, 0.23, 0.38, 0.4, 0.5, 0.66, 0.7, or 0.79, etc. It can be understood that by restricting the ratio of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the ultra-telephoto end of the optical lens 10 within the range of 0.2 to 0.8, the value range of ft / fs is relatively wide, the value ranges of the zoom ratio and the zoom magnification of the optical lens 10 are larger, and the optical lens 10 has a larger field of view coverage range.

[0261] In other embodiments, the ratio ft / fs of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the ultra-telephoto end of the optical lens 10 can also satisfy other ranges. Specifically, the present application does not make any limitations.

[0262] Exemplarily, the optical lens 10 can satisfy:

[0263] 1 < fse / fte < 5, where fse = (fs × 43.27) / IHs, fte = (ft × 43.27) / IHt, IHs is the image height at the ultra-telephoto end of the optical lens 10, and IHt is the image height at the telephoto end of the optical lens 10. For example, fse / fte can be equal to 1.1, 1.8, 2, 3.6, 4, 4.5, or 4.99, etc. It can be understood that the smaller the value of the zoom ratio fse / fte of the optical lens 10, the smaller the zoom ratio, and the larger the value of the zoom ratio fse / fte of the optical lens 10, the larger the zoom ratio. Thus, by restricting the zoom ratio fse / fte of the optical lens 10 within the range of 1 to 5, the value range of the zoom ratio of the optical lens 10 is relatively wide, and the optical lens 10 can simultaneously achieve a shorter focal length and a longer focal length, which is beneficial to achieving shooting at the ultra-telephoto end and the telephoto end of the optical lens 10.

[0264] In other embodiments, 1 < fse / fte < 5 can also satisfy other ranges. Specifically, this application does not make a limitation.

[0265] Exemplarily, the optical lens 10 can satisfy: 1.0 < f1 / ft < 5, where f1 is the focal length of the first lens group G1. For example, f1 / ft can be equal to 1.1, 1.6, 2, 2.38, 2.66, 3, 3.72, 4, 4.5, or 4.9, etc. It can be understood that by restricting the ratio of the focal length f1 of the first lens group G1 to the focal length ft of the telephoto end of the optical lens 10 within the range of 1.0 to 5, the optical anti-shake performance of the first lens group G1 is improved, thereby improving the optical anti-shake performance of the optical lens 10.

[0266] In other embodiments, the ratio f1 / ft of the focal length f1 of the first lens group G1 to the focal length ft of the telephoto end of the optical lens 10 can also satisfy other ranges. Specifically, this application does not make a limitation.

[0267] Exemplarily, the optical lens 10 can satisfy: |ft × (1 / f123t - 1 / f12)| < 5, where f123t is the combined focal length of the first lens group G1, the second lens group G2, and the third lens group G3 at the telephoto end of the optical lens 10, and f12 is the combined focal length of the first lens group G1 and the second lens group G2. For example, |ft × (1 / f123t - 1 / f12)| can be equal to 0.1, 1, 1.5, 1.8, 2.3, 3.6, 4, or 4.9, etc. It can be understood that the smaller the value of |ft × (1 / f123t - 1 / f12)|, the lower the focusing sensitivity of the optical lens 10, and the larger the value, the higher the focusing sensitivity of the optical lens 10. Thus, by restricting |ft × (1 / f123t - 1 / f12)| within the range less than 5, the focusing of the optical lens 10 can be accurately controlled, and the focusing effect of the optical lens 10 is improved.

[0268] In other embodiments, |ft×(1 / f123t - 1 / f12)| may also satisfy other ranges. Specifically, this application does not make any limitations.

[0269] Exemplarily, the optical lens 10 may satisfy: |fs×(1 / f123s - 1 / f12)| < 5, where f123s is the combined focal length of the first lens group G1, the second lens group G2, and the third lens group G3 at the ultra-telephoto end of the optical lens 10. For example, |fs×(1 / f123s - 1 / f12)| may be equal to 0.1, 0.8, 1, 1.5, 2, 3.7, 4, or 4.99, etc. It can be understood that the smaller the value of |fs×(1 / f123s - 1 / f12)|, the lower the focusing sensitivity of the optical lens 10, and the larger the value, the higher the focusing sensitivity of the optical lens 10. Thus, by restricting

[0270] |fs×(1 / f123s - 1 / f12)| within a range less than 5, the focusing of the optical lens 10 can be precisely controlled, and the focusing effect of the optical lens 10 can be improved.

[0271] In other embodiments, |fs×(1 / f123s - 1 / f12)| may also satisfy other ranges. Specifically, this application does not make any limitations.

[0272] Exemplarily, the optical lens 10 may satisfy: -10 < f12 / f3 < 0, where f3 is the focal length of the third lens group G3. For example, f12 / f3 may be equal to -9.9, -8, -7.5, -6.6, -5.3, -4, -3.8, -2, -1, or -0.5, etc. It can be understood that the smaller the value of f12 / f3, the longer the combined focal length of the first lens group G1 and the second lens group G2, and the shorter the focal length of the third lens group G3; the larger the value, the shorter the combined focal length of the first lens group G1 and the second lens group G2, and the longer the focal length of the third lens group G3. Thus, by restricting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 within the range of -10 to 0, the optical anti-shake performance of the first lens group G1 is improved, thereby improving the optical anti-shake performance of the optical lens 10.

[0273] In other embodiments, the ratio f12 / f3 of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 may also satisfy other ranges. Specifically, this application does not make any limitations.

[0274] Exemplarily, when the optical lens 10 is at the telephoto end, the third lens group G3 can move towards the direction close to the first lens group G1. The optical lens 10 can satisfy: Redt > 0.15, where Redt is the magnification factor of the telephoto end of the optical lens 10 in the macro state. For example, Redt can be equal to 0.16, 0.3, 0.5, 1, 2, 2.5, or 3, etc. It can be understood that by restricting the magnification factor Redt of the telephoto end of the optical lens 10 in the macro state within the range greater than 0.15, the magnification factor Redt of the telephoto end of the optical lens 10 in the macro state is relatively large, which is beneficial to achieving the shooting of the shooting object in the macro state by the optical lens 10.

[0275] In other embodiments, the magnification factor Redt of the telephoto end of the optical lens 10 in the macro state can also satisfy other ranges. Specifically, this application does not make any limitations.

[0276] Exemplarily, when the optical lens 10 is at the ultra-telephoto end, the third lens group G3 can move towards the direction close to the first lens group G1. The optical lens 10 can satisfy: Reds > 0.025, where Reds is the magnification factor of the ultra-telephoto end of the optical lens 10 in the near state. For example, Reds can be equal to 0.026, 0.05, 0.1, 0.5, 1, 1.8, 2.5, 3, or 5, etc. It can be understood that by restricting the magnification factor Reds of the ultra-telephoto end of the optical lens 10 in the near state within the range greater than 0.025, the magnification factor Reds of the ultra-telephoto end of the optical lens 10 in the near state is relatively large, which is beneficial to achieving the shooting of the shooting object in the near state by the optical lens 10.

[0277] In other embodiments, the magnification factor Reds of the ultra-telephoto end of the optical lens 10 in the near state can also satisfy other ranges. Specifically, this application does not make any limitations.

[0278] Exemplarily, when the optical lens 10 is at the ultra-telephoto end, the fourth lens group G4 can move away from the first lens group G1 and the second lens group G2. The optical lens 10 can satisfy: 0.15 < Redss < 1.0, where Redss is the magnification factor of the ultra-telephoto end of the optical lens 10 in the macro state. For example, Redss can be equal to 0.16, 0.28, 0.33, 0.45, 0.5, 0.66, 0.7, 0.8, 0.95, or 0.99, etc. It can be understood that by restricting the magnification factor Redss of the ultra-telephoto end of the optical lens 10 in the macro state within the range of 0.15 to 1.0, the magnification factor Redss of the ultra-telephoto end of the optical lens 10 in the macro state is relatively appropriate, and the optical lens 10 can achieve shooting with a relatively large magnification factor for a relatively far shooting object.

[0279] In other embodiments, the magnification Redss of the super telephoto end of the optical lens 10 in the macro state may also meet other ranges, which are not specifically limited in this application.

[0280] For example, the lens material of the first lens group G1 can be resin. It is understood that the lenses of the first lens group G1 are relatively light, which helps reduce the overall weight of the optical lens 10. Furthermore, the lenses of the first lens group G1 have good resistance to vibration and impact.

[0281] For example, the lens material of the first lens group G1 can also be glass. It is understood that the lenses of the first lens group G1 have excellent optical transparency, refractive index and chemical stability, are not easily scratched or deformed, and are conducive to the optical lens 10 achieving clear and accurate imaging.

[0282] In other embodiments, the lenses of the first lens group G1 may also be made of other materials, which is not specifically limited in this application.

[0283] Exemplarily, the material of the deflecting element 1a is resin, glass, metal, film material or mixed material.

[0284] For example, when the deflecting element 1a is made of resin, the deflecting element 1a is light in weight, which helps reduce the overall weight of the optical lens 10. In addition, resin has good processing properties and has a lower manufacturing cost than glass.

[0285] For example, when the material of the folding element 1a is glass, the folding element 1a has excellent optical properties, can reduce the optical distortion of the optical lens 10, and the folding element 1a has good durability and stability, and the folding element 1a can perform stably in various usage environments.

[0286] For example, when the material of the deflection element 1a is metal, the deflection element 1a can have high mechanical strength and durability, and the metal can effectively conduct heat, so the deflection element 1a is not prone to overheating during operation.

[0287] For example, when the material of the folding element 1a is a film material, that is, the surface of the folding element 1a is coated with a film material, the film material enables the folding element 1a to achieve total reflection, and the film material can adjust the reflectivity of the folding element 1a, thereby reducing the loss of light and thereby improving the resolution and imaging quality of the optical lens 10.

[0288] Exemplarily, when the material of the deflection element 1a is a mixed material, that is, the deflection element 1a can be a mixed material component composed of one or more different materials. The mixed material can combine the advantages of different materials, so that the deflection element 1a can achieve total reflection, and the performance of the deflection element 1a is better.

[0289] In other embodiments, the deflecting element 1a may also be made of other materials, which is not specifically limited in this application.

[0290] For example, the lens material of the second lens group G2 can be resin. It is understood that the lenses of the second lens group G2 are relatively light, which helps reduce the overall weight of the optical lens 10. In addition, the lenses of the second lens group G2 have good resistance to vibration and impact.

[0291] For example, the lens material of the second lens group G2 can also be glass. It is understood that the lenses of the second lens group G2 have excellent optical transparency, refractive index and chemical stability, are not easily scratched or deformed, and are conducive to the optical lens 10 to achieve clear and accurate imaging.

[0292] In other embodiments, the lenses of the second lens group G2 may also be made of other materials, which is not specifically limited in this application.

[0293] For example, the lenses of the third lens group G3 can be made of resin. It is understood that the lenses of the third lens group G3 are relatively light, which helps reduce the overall weight of the optical lens system 10. Furthermore, the lenses of the third lens group G3 are highly resistant to vibration and impact.

[0294] For example, the lens material of the third lens group G3 can also be glass. It is understood that the lenses of the third lens group G3 have excellent optical transparency, refractive index and chemical stability, are not easily scratched or deformed, and are conducive to the optical lens 10 to achieve clear and accurate imaging.

[0295] In other embodiments, the lenses of the third lens group G3 may also be made of other materials, which is not specifically limited in this application.

[0296] For example, the lenses of the fourth lens group G4 can be made of resin. It is understood that the lenses of the fourth lens group G4 are relatively light, which helps reduce the overall weight of the optical lens system 10. Furthermore, the lenses of the fourth lens group G4 are highly resistant to vibration and impact.

[0297] Exemplarily, the lens material of the lenses in the fourth lens group G4 can also be glass. It can be understood that the lens lenses of the fourth lens group G4 have excellent optical transparency, refractive index, and chemical stability, are not easily scratched or deformed, which is conducive to the optical lens 10 achieving clear and accurate imaging.

[0298] In other embodiments, the lens lenses of the fourth lens group G4 can also use other materials. Specifically, this application does not make any limitations.

[0299] Exemplarily, the optical lens 10 can satisfy: 1.4 < Nd < 2.1, 15 < Vd < 96, where Nd is the refractive index of the material of each lens lens of the optical lens 10, and Vd is the Abbe number of each lens lens of the optical lens 10. For example, Nd can be equal to 1.45, 1.5, 1.61, 1.7, 1.83, 1.95, 2, or 2.05, etc., and Vd can be equal to 16, 18, 23, 28, 35.6, 40.5, 51, 63.2, 78.5, 80, 85, 91, or 95, etc. It can be understood that by restricting the refractive index Nd of the material of each lens lens of the optical lens 10 within the range of 1.4 to 2.1, and restricting the Abbe number Vd of each lens lens of the optical lens 10 within the range of 15 to 96, the refractive index of each lens lens of the optical lens 10 is smaller, the Abbe number is larger, and the light transmittance of each lens lens of the optical lens 10 is higher. In this way, the light penetration ability of each lens lens of the optical lens 10 is stronger, the optical quality of each lens lens of the optical lens 10 is higher, and the images captured by the optical lens 10 are clearer.

[0300] In other embodiments, Nd can also satisfy other ranges, and Vd can also satisfy other ranges. Specifically, this application does not make any limitations.

[0301] Exemplarily, the optical lens 10 can satisfy: -5 < f2 / fs < 0, where f2 is the focal length of the second lens group G2. For example, f2 / fs can be equal to -4.9, -4.5, -3.8, -3, -2.5, -1, or -0.1, etc. It can be understood that the smaller the value of f2 / fs, the lower the sensitivity of the second lens group G2, and the larger the value, the higher the sensitivity of the second lens group G2. In this way, by restricting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-long focal end of the optical lens 10 within the range of -5 to 0, the assembly tolerance between the first lens group G1 to the fourth lens group G4 is increased, and the loss of the resolution of the optical lens 10 is reduced.

[0302] In other embodiments, the ratio f2 / fs of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-long focal end of the optical lens 10 can also satisfy other ranges. Specifically, this application does not make any limitations.

[0303] Exemplarily, the optical lens 10 may satisfy: -8 < f1 / f2 < 0. For example, f1 / f2 may be equal to -4.9, -4, -3.8, -3, -2.3, -1, -0.5, or -0.1, etc. It can be understood that by restricting the ratio of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 within the range of -8 to 0, the distribution of the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 is relatively reasonable. Under this distribution of the optical power, by reasonably setting the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance among aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be realized.

[0304] In other embodiments, the ratio f1 / f2 of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 may also satisfy other ranges. Specifically, this application does not make a limitation.

[0305] Some specific but non-limiting examples of the embodiments of the present application will be described in more detail below in conjunction with the relevant drawings.

[0306] As Figures 3A to 3C shown, exemplarily, the camera module 300 includes a first lens group G1, a second lens group G2, an aperture 5 (not shown in the appended Figure 3A appendices Figure 3C ), a third lens group G3, a fourth lens group G4, a filter 30, and an image sensor 20, which are arranged in sequence from the object side to the image side.

[0307] Exemplarily, the first lens group G1 includes a first lens L1 and a folding element 1a. The second lens group G2 includes a second lens L2. The third lens group G3 includes a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens L6. The fourth lens group G4 includes a seventh lens L7, an eighth lens L8, and a ninth lens L9.

[0308] Exemplarily, the first lens L1, the third lens L3, the fifth lens L5, the sixth lens L6, and the eighth lens L8 may all have positive optical power. The second lens L2, the fourth lens L4, the seventh lens L7, and the ninth lens L9 may all have negative optical power.

[0309] Exemplarily, when the optical lens 10 continuously zooms from the telephoto end to the middle section, and then continuously zooms to the super telephoto end, and focuses on the object at infinity, the first lens group G1 and the second lens group G2 are fixed lens groups, and the position of the first lens group G1 relative to the imaging plane in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can simultaneously move along the optical axis of the first sub-direction of the second direction, so that the distance between the second lens group G2 and the third lens group G3 is reduced, and the distance between the third lens group G3 and the fourth lens group G4 is reduced. The optical zoom ratio of the optical lens 10 can be in the range of 3X to 8X (including 3X and 8X). For example, the optical zoom ratio of the optical lens 10 can be 3X, 3.5X, 4X, 5X, 6.2X, 7X or 8X, etc. In other embodiments, the optical zoom ratio of the optical lens 10 can also meet other satisfying ranges.

[0310] For example, when the optical lens 10 is at a shorter focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both smaller. When the optical lens 10 is at a longer focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both larger. The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction is smaller than the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction. That is, the third lens group G3 and the fourth lens group G4 may satisfy the relationship: ΔG3<ΔG4.

[0311] Exemplarily, the focal length f1 of the first lens group G1 satisfies: f1>0, that is, the first lens group G1 may have positive refractive power. Exemplarily, the focal length f2 of the second lens group G2 may satisfy: f2<0, that is, the second lens group G2 may have negative refractive power. The focal length f3 of the third lens group G3 may satisfy: f3>0, that is, the third lens group G3 may have positive refractive power. The focal length f4 of the fourth lens group G4 may satisfy: f4<0, that is, the fourth lens group G4 may have negative refractive power.

[0312] For example, the deflecting element 1a can be a prism that changes the direction of propagation of the optical axis from a first direction to a second direction, deflecting light emitted by the first lens L1 before it enters the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a single two-dimensional plane, namely, the XZ plane.

[0313] For example, the first lens group G1 has an anti-shake compensation function, and can implement optical image stabilization of the optical lens 10. During the optical image stabilization process of the optical lens 10, the first lens group G1 can rotate around the first direction, the second direction, or the third direction.

[0314] Some design parameters of the camera module 300 according to the first embodiment of the present application are shown in Table 1a below.

[0315] Table 1a Partial design parameters of each lens of the camera module 300 in the first embodiment

[0316]

[0317]

[0318] It can be understood that in Table 1a, OBJ can represent the object side surface of the camera module 300; S1 and S2 can represent the object side surface and image side surface of the first lens L1 respectively; S3 and S4 can represent the object side surface and image side surface of the folding element 1a respectively; S5 can represent the aperture 5 (attached Figure 1B , S14 and S15 may represent the object-side surface and the image-side surface of the sixth lens L6; S16 and S17 may represent the object-side surface and the image-side surface of the seventh lens L7; S18 and S19 may represent the object-side surface and the image-side surface of the eighth lens L8; S20 and S21 may represent the object-side surface and the image-side surface of the ninth lens L9; S22 and S23 may represent the object-side surface and the image-side surface of the filter 30; and S24 may represent the imaging surface of the camera module 300.

The thickness of S4 refers to the distance between the image side surface of the refracting element 1a and the object side surface of the aperture 5. The thickness of S5 refers to the distance between the object side surface of the aperture 5 and the image side surface of the aperture 5.

The thickness of S8 refers to the distance between the image side surface of the second lens L2 and the object side surface of the third lens L3. The thickness of S9 refers to the distance between the object side surface of the third lens L3 and the image side surface of the third lens L3. The thickness of S10 refers to the distance between the image-side surface of the third lens L3 and the object-side surface of the fourth lens group G4. The thickness of S11 refers to the distance between the object-side surface of the fourth lens L4 and the image-side surface of the fourth lens L4. The thickness of S12 refers to the distance between the image-side surface of the fourth lens L4 and the object-side surface of the fifth lens L5. The thickness of S13 refers to the distance between the object-side surface of the fifth lens L5 and the image-side surface of the fifth lens L5. The thickness of S14 refers to the distance between the image-side surface of the fifth lens L5 and the object-side surface of the sixth lens L6. The thickness of S15 refers to the distance between the object-side surface of the sixth lens L6 and the image-side surface of the sixth lens L6. The thickness of S16 refers to the distance between the image-side surface of the sixth lens L6 and the object-side surface of the seventh lens L7. The thickness of S17 refers to the distance between the object-side surface of the seventh lens L7 and the image-side surface of the seventh lens L7. The thickness of S18 refers to the distance between the image-side surface of the seventh lens L7 and the object-side surface of the eighth lens L8. The thickness of S19 refers to the distance between the object-side surface of the eighth lens L8 and the image-side surface of the eighth lens L8.

The thickness of S22 refers to the distance between the image-side surface of the ninth lens element L9 and the object-side surface of the optical filter 30. The thickness of S23 refers to the distance between the object-side surface of the optical filter 30 and the image-side surface of the optical filter 30. The thickness of S24 refers to the distance between the image-side surface of the optical filter 30 and the imaging surface.

[0320] In Table 1a, the thickness values, with positive and negative signs, represent the direction of thickness. For example, the direction of light not reflected by the deflecting element 1a is positive, and the thickness value is positive; the direction of light reflected by the deflecting element 1a is negative, and the thickness value is negative. It should be understood that if the meaning of each table is the same when it appears again in subsequent tables, it will not be repeated.

[0321] In other embodiments, the direction of the light after being reflected by the deflecting element 1a can be positive, and the thickness can be positive; the direction of the light without being reflected by the deflecting element 1a can be negative, and the thickness can be negative.

[0322] The first lens L1, the third lens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6, the seventh lens L7, the eighth lens L8, the ninth lens L9, and the filter 30 are all made of resin, while the second lens L2 and the deflecting element 1a are both made of glass. It will be appreciated that the combination of resin and glass lenses enables the camera module 300 to have a lighter weight, greater durability, and superior optical performance.

[0323] In addition, the aspheric coefficients of each lens of the camera module 300 according to the first embodiment of the present application are shown in Table 1b below.

[0324] Table 1b Aspheric coefficients of each lens of the camera module 300 in the first embodiment

[0325]

[0326] Among them, A4, A6, A8, A 10 、A 12 、A 14 、A 16 、A 18 、A 20 、A 22 、A 24 、A 26 、A 28 and A 30 Indicates the aspheric coefficient. Polynomial coefficients that do not exist in the table (such as A1, A2, A3, etc.) are all 0. It is understood that the parameters in the table are expressed in scientific notation. For example, 5.8E-06 means 5.8×10 -6 ;-5.2E-07 means -5.2×10 -7 .

[0327] It is understood that among the 18 aspheric surfaces of the camera module 300 shown in Table 1a and Table 1b, the surface types z of all even-order and odd-order aspheric surfaces can be defined using, but not limited to, the following aspheric surface formula:

[0328]

[0329] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex curvature of the aspheric surface, K is the quadratic surface constant, A i Denotes the i-th order aspheric coefficient. Substituting the design parameters of the first lens L1 to the ninth lens L9 of the camera module 300 into the above aspheric formula, the object-side and image-side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 according to the first embodiment of the present application can be obtained.

[0330] According to the data in Table 1a and Table 1b, some parameters of the camera module 300 of the first embodiment of the present application can be obtained, as shown in Table 1c below.

[0331] Table 1c Partial parameters of the camera module 300 of the first embodiment

[0332] fL1 fL2 fL3 fL4 fL5 fL6 fL7 fL8 fL9 58.05 -23.13 11.41 -16.42 23.32 25.96 -50.09 22.80 -9.65

[0333] Among them, fL1 may represent the focal length of the first lens L1; fL2 may represent the focal length of the second lens L2; ​​fL3 may represent the focal length of the third lens L3; fL4 may represent the focal length of the fourth lens L4; fL5 may represent the focal length of the fifth lens L5; fL6 may represent the focal length of the sixth lens L6; fL7 may represent the focal length of the seventh lens L7; fL8 may represent the focal length of the eighth lens L8; and fL9 may represent the focal length of the ninth lens L9. It should be understood that in this application, when symbols representing the same meaning appear again in subsequent tables, they will not be repeated.

[0334] It can be understood that the focal length fL1 of the first lens L1 satisfies: fL1 = 58.05 mm (millimeter), and the first lens L1 can have positive focal power; the focal length fL2 of the second lens L2 satisfies: fL2 = -23.13 mm, and the second lens L2 can have negative focal power; the focal length fL3 of the third lens L3 satisfies: fL3 = 11.41 mm, and the third lens L3 can have positive focal power; the focal length fL4 of the fourth lens L4 satisfies: fL4 = -16.42 mm, and the fourth lens L4 can have negative focal power; the focal length fL5 of the fifth lens L5 satisfies: fL5=23.32 mm, and the fifth lens L5 may have positive focal power; the focal length fL6 of the sixth lens L6 satisfies: fL6=25.96 mm, and the sixth lens L6 may have positive focal power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-50.09 mm, and the seventh lens L7 may have negative focal power; the focal length fL8 of the eighth lens L8 satisfies: fL8=22.80 mm, and the eighth lens L8 may have positive focal power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-9.65 mm, and the ninth lens L9 may have negative focal power.

[0335] It can be understood that the first lens L1 to the ninth lens L9 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0336] According to the data in Table 1a and Table 1b, some parameters of the camera module 300 of the first embodiment of the present application can be obtained, as shown in Table 1d below.

[0339] Among them, f4 can represent the focal length of the fourth lens group G4, and fm can represent the focal length of the camera module 300 in the middle section. It is understood that in this application, when symbols with the same meaning appear again in subsequent tables, they will not be repeated.

[0340] It can be understood that the focal length f1 of the first lens group G1 satisfies: f1=58.05mm, and the first lens group G1 can have positive focal power; the focal length f2 of the second lens group G2 satisfies: f2=-23.13mm, and the second lens group G2 can have negative focal power; the focal length f3 of the third lens group G3 satisfies: f3=10.74mm, and the third lens group G3 can have positive focal power; the focal length f4 of the fourth lens group G4 satisfies: f4=-11.08mm, and the fourth lens group G4 can have negative focal power.

[0341] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0342] The focal length ft at the telephoto end of the optical lens 10 and the focal length fs at the super-telephoto end of the optical lens 10 satisfy the following relationship: ft / fs = 0.75. It is understood that by limiting the ratio of the focal length ft at the telephoto end of the optical lens 10 to the focal length fs at the super-telephoto end of the optical lens 10 to 0.75, the zoom ratio and zoom magnification of the optical lens 10 can have a wider range of values, and the optical lens 10 has a wider field of view.

[0343] The optical lens 10 satisfies the following condition: fse / fte = 2.64. It is understood that by limiting fse / fte to 2.64, the zoom ratio of the optical lens 10 is appropriately selected, allowing the optical lens 10 to simultaneously achieve both shorter and longer focal lengths, facilitating shooting at both the super-telephoto and telephoto ends of the optical lens 10.

[0344] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction satisfy: ΔG4 / ΔG3=1.45. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction to the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction to be equal to 1.45, the movement distances of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the movement distances of the third lens group G3 and the fourth lens group G4 driven by the driving mechanism are relatively small, which is conducive to achieving a miniaturized configuration of the optical lens 10. At the same time, the structure of the driving mechanism is more simple.

[0345] The focal length f1 of the first lens group G1 and the focal length ft at the telephoto end of the optical lens 10 satisfy the following relationship: f1 / ft=2.47. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length ft at the telephoto end of the optical lens 10 to 2.47, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0346] The focal length ft at the telephoto end of the optical lens 10, the combined focal length f123t of the first lens group G1, the second lens group G2, and the third lens group G3 at the telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0347] |ft×(1 / f123t-1 / f12)|=1.90. It can be understood that by limiting |ft×(1 / f123t-1 / f12)| to 1.90, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0348] Among them, the focal length fs at the super telephoto end of the optical lens 10, the combined focal length f123s of the first lens group G1, the second lens group G2 and the third lens group G3 at the super telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0349] |fs×(1 / f123s−1 / f12)|=2.40. It can be understood that by limiting |fs×(1 / f123s−1 / f12)| to 2.40, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0350] The combined focal length f12 of the first lens group G1 and the second lens group G2 and the focal length f3 of the third lens group G3 satisfy:

[0351] f12 / f3=-5.86. It can be understood that by limiting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 to -5.86, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0352] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt = 0.635. It is understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to 0.635, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, thereby facilitating the optical lens 10 to photograph subjects at macro distances.

[0353] The magnification Reds of the super-telephoto end of the optical lens 10 at close range satisfies the following condition: Reds = 0.03. It is understood that by limiting the magnification Reds of the super-telephoto end of the optical lens 10 at close range to 0.03, the magnification Reds of the super-telephoto end of the optical lens 10 at close range is larger, which facilitates the optical lens 10 in photographing close-range subjects.

[0354] Among them, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state satisfies: Redss = 0.23. It can be understood that by restricting the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state to be equal to 0.23, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state is more appropriate, and the optical lens 10 can achieve shooting with a larger magnification for a relatively distant shooting object.

[0355] Among them, the refractive index Nd of the material of each lens of the optical lens 10 and the Abbe number Vd of each lens of the optical lens 10 satisfy:

[0356] 1.51 < Nd < 1.77, 20.40 < Vd < 56.00. It can be understood that by restricting the refractive index Nd of the material of each lens of the optical lens 10 to be within the range of 1.51 to 1.77 and restricting the Abbe number Vd of each lens of the optical lens 10 to be within the range of 20.40 to 56.00, the refractive index of each lens of the optical lens 10 is smaller and the Abbe number is larger, and the light transmittance of the lenses of each lens of the optical lens 10 is higher. In this way, the light penetration power of the lenses of each lens of the optical lens 10 is stronger, the optical quality of each lens of the optical lens 10 is higher, and the image captured by the optical lens 10 is clearer.

[0357] Among them, the focal length f2 of the second lens group G2 and the focal length fs of the ultra-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.74. It can be understood that by restricting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-telephoto end of the optical lens 10 to be equal to -0.74, the assembly tolerance between the first lens group G_{1} to the fourth lens group G_{4} is increased, and the loss of the resolution of the optical lens 10 is reduced.

[0358] Among them, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 satisfy: f1 / f_{}2 = -2.51. It can be understood that by restricting the ratio of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 to be equal to -2.51, the focal lengths f1 of the first lens group G1 and f2 of the second lens group G2 are reasonably allocated. Under this distribution of the optical power, by reasonably setting the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance among aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be realized.

[0359] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction, the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction, and the focal length fs of the optical lens 10 at the super-telephoto end satisfy: |(ΔG3+ΔG4) / fs|=0.23. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to 0.23, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, thereby facilitating a compact design of the optical lens 10.

[0360] Figure 6A FIG1 is a simulation effect diagram of the telephoto end of the camera module 300 according to the first embodiment.

[0361] It is understandable that Figure 6A The curve can represent the along-axis chromatic aberration curve of the camera module 300. The axial chromatic aberration curve can represent the deviation of the focal point of light of different wavelengths after passing through the lenses of the optical system. The reference wavelengths of the axial chromatic aberration curve are 435nm, 470nm, 510nm, 555nm, 610nm and 650nm. Its physical meaning is the deviation of the light of the corresponding wavelength emitted in the 0-degree field of view from the ideal image point after passing through the optical lens 10; its horizontal coordinate is the deviation value along the optical axis, and the vertical coordinate is the normalized coordinate at the pupil. It can be understood that in this application, when it appears again in the subsequent coordinate system representing the along-axis chromatic aberration curve of the camera module 300, the horizontal coordinate, vertical coordinate and annotations in the figure that represent the same meaning will not be repeated.

[0362] like Figure 6A As shown, when the camera module 300 is at the telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0363] Figure 6B FIG1 is a simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the first embodiment.

[0364] like Figure 6B As shown, when the camera module 300 is at the super telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0365] Figure 7A FIG2 is a second simulation effect diagram of the telephoto end of the camera module 300 according to the first embodiment.

[0366] It is understandable that Figure 7AThe curve can represent the astigmatic field curvature curve of camera module 300. The astigmatic field curvature curve can represent meridional image curvature and sagittal image curvature, and is used to illustrate the deviation of the convergence point of light beams with different fields of view from the ideal imaging plane. The solid line represents the light beam in the meridional direction, and the dashed line represents the light beam in the sagittal direction. The abscissa represents the deviation along the optical axis O, and the ordinate represents the corresponding field of view. It should be understood that in this application, when the coordinate system representing the astigmatic field curvature curve of camera module 300 appears again in subsequent references, the abscissa, ordinate, and annotations in the figure that represent the same meaning will not be repeated.

[0367] like Figure 7A As shown, when the camera module 300 is at the telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0368] Figure 7B FIG2 is a second simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the first embodiment.

[0369] like Figure 7B As shown, when the camera module 300 is at the super telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0370] Figure 8A FIG3 is a simulation effect diagram of the telephoto end of the camera module 300 according to the first embodiment.

[0371] It is understandable that Figure 8A The curve can represent the distortion curve of the camera module 300. The distortion curve can represent the relative deviation between the convergence point of light beams in different fields of view (actual image height) and the ideal image height, where the horizontal axis represents the optical distortion ratio and the vertical axis represents the image height IH (mm). It is understood that in this application, when the coordinate system representing the distortion curve of the camera module 300 appears again in the subsequent coordinate system, the horizontal axis, vertical axis, and annotations in the figure that represent the same meaning will not be repeated.

[0372] like Figure 8A As shown, when the camera module 300 is at the telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 2%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0373] Figure 8B FIG3 is a simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the first embodiment.

[0374] like Figure 8BAs shown, when the camera module 300 is at the super telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 1%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0375] Second implementation method: Figure 9A yes Figure 1B The second simplified schematic diagram of a partial structure of the camera module 300 in one embodiment is shown. Figure 9B yes Figure 9A The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 9C yes Figure 9B The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figures 9A to 9C The camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0376] like Figures 9A to 9C As shown, the camera module 300 includes a first lens group G1, a second lens group G2, a stop 5 (attached), and a plurality of lens elements arranged in sequence from the object side to the image side. Figure 9A To the attached Figure 9C (not shown), the third lens group G3, the fourth lens group G4, the filter 30 and the image sensor 20.

[0377] Illustratively, the first lens group G1 includes a first lens L1 and a deflecting element 1a. The second lens group G2 includes a second lens L2. The third lens group G3 includes a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens L6. The fourth lens group G4 includes a seventh lens L7, an eighth lens L8, and a ninth lens L9.

[0378] For example, the first lens L1, the third lens L3, the fifth lens L5, the sixth lens L6, and the eighth lens L8 may all have positive refractive power, and the second lens L2, the fourth lens L4, the seventh lens L7, and the ninth lens L9 may all have negative refractive power.

[0379] like Figures 9A to 9CAs shown, for example, when the optical lens 10 continuously zooms from the telephoto end to the intermediate section, and then continuously zooms to the super telephoto end, and focuses on the object at infinity, the first lens group G1 and the second lens group G2 are fixed lens groups, and the position of the first lens group G1 relative to the imaging plane in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can simultaneously move along the optical axis of the first sub-direction of the second direction, so that the distance between the second lens group G2 and the third lens group G3 is reduced, and the distance between the third lens group G3 and the fourth lens group G4 is reduced. The optical zoom ratio of the optical lens 10 can be in the range of 3X to 8X (including 3X and 8X). For example, the optical zoom ratio of the optical lens 10 can be 3X, 3.5X, 4X, 5X, 6.2X, 7X or 8X, etc. In other embodiments, the optical zoom ratio of the optical lens 10 can also meet other satisfying ranges.

[0380] For example, when the optical lens 10 is at a shorter focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both smaller. When the optical lens 10 is at a longer focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both larger. The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction is smaller than the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction. That is, the third lens group G3 and the fourth lens group G4 may satisfy the relationship: ΔG3<ΔG4.

[0381] Exemplarily, the focal length f1 of the first lens group G1 satisfies: f1>0, that is, the first lens group G1 may have positive refractive power. Exemplarily, the focal length f2 of the second lens group G2 may satisfy: f2<0, that is, the second lens group G2 may have negative refractive power. The focal length f3 of the third lens group G3 may satisfy: f3>0, that is, the third lens group G3 may have positive refractive power. The focal length f4 of the fourth lens group G4 may satisfy: f4<0, that is, the fourth lens group G4 may have negative refractive power.

[0382] For example, the deflecting element 1a can be a prism that changes the direction of propagation of the optical axis from a first direction to a second direction, deflecting light emitted by the first lens L1 before it enters the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a single two-dimensional plane, namely, the XZ plane.

[0383] For example, the first lens group G1 has an anti-shake compensation function, and can implement optical image stabilization of the optical lens 10. During the optical image stabilization process of the optical lens 10, the first lens group G1 can rotate around the first direction, the second direction, or the third direction.

[0384] Figure 10A yes Figure 9C The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 10B yes Figure 10A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figure 10A and Figure 10B The camera module 300 is in the close-range state at the super-telephoto end and the macro state at the super-telephoto end respectively.

[0385] like Figure 9C and Figure 10A As shown, for example, during zooming of the camera module 300 from the ultra-telephoto end to the ultra-telephoto end at close range, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, while the third lens group G3 can move along the optical axis in the first sub-direction. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0386] In some embodiments, during the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0387] like Figure 10A and Figure 10B As shown, for example, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis in the second sub-direction. In this case, the distance between the fourth lens group G4 and the third lens group G3 is further increased.

[0388] In some embodiments, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0389] Figure 11 yes Figure 9A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in another embodiment. It can be understood that Figure 11 The camera module 300 is in the macro state at the telephoto end.

[0390] like Figure 9A and Figure 11 As shown, for example, during zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, while the third lens group G3 can move along the optical axis in the first sub-direction. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0391] In some embodiments, during the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. This application does not limit this specifically.

The thickness of S14 refers to the distance between the image-side surface of the fifth lens L5 and the object-side surface of the sixth lens L6. The thickness of S15 refers to the distance between the object-side surface of the sixth lens L6 and the image-side surface of the sixth lens L6. The thickness of S16 refers to the distance between the image-side surface of the sixth lens L6 and the object-side surface of the seventh lens L7.

[0398] The first lens L1, the third lens L3, the fourth lens L4, the fifth lens L5, the seventh lens L7, the eighth lens L8, and the ninth lens L9 are all made of resin, while the second lens L2, the deflecting element 1a, the sixth lens L6, and the filter 30 are all made of glass.

[0403] It is understood that among the 18 aspheric surfaces of the camera module 300 shown in Table 2a and Table 2b, the surface types z of all even-order and odd-order aspheric surfaces can be defined using, but not limited to, the following aspheric surface formula:

[0404]

[0405] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex curvature of the aspheric surface, K is the quadratic surface constant, A i Denotes the i-th order aspheric coefficient. Substituting the design parameters of the first lens L1 to the ninth lens L9 of the camera module 300 into the above aspheric formula, the object-side and image-side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 according to the second embodiment of the present application can be obtained.

[0406] Based on the data in Table 2a and Table 2b, some parameters of the camera module 300 of the second embodiment of the present application can be obtained, as shown in Table 2c below.

[0407] Table 2c Partial parameters of the camera module 300 of the second embodiment

[0408] fL1 fL2 fL3 fL4 fL5 fL6 fL7 fL8 fL9 56.96 -21.95 10.81 -22.96 26.78 18.49 -19.63 19.05 -12.36

[0409] It can be understood that the focal length fL1 of the first lens L1 satisfies: fL1 = 56.96 mm (millimeter), and the first lens L1 can have positive focal power; the focal length fL2 of the second lens L2 satisfies: fL2 = -21.95 mm, and the second lens L2 can have negative focal power; the focal length fL3 of the third lens L3 satisfies: fL3 = 10.81 mm, and the third lens L3 can have positive focal power; the focal length fL4 of the fourth lens L4 satisfies: fL4 = -22.96 mm, and the fourth lens L4 can have negative focal power; the focal length fL5 of the fifth lens L5 satisfies: fL5=26.78 mm, and the fifth lens L5 may have positive focal power. The focal length fL6 of the sixth lens L6 satisfies: fL6=18.49 mm, and the sixth lens L6 may have positive focal power. The focal length fL7 of the seventh lens L7 satisfies: fL7=-19.63 mm, and the seventh lens L7 may have negative focal power. The focal length fL8 of the eighth lens L8 satisfies: fL8=19.05 mm, and the eighth lens L8 may have positive focal power. The focal length fL9 of the ninth lens L9 satisfies: fL9=-12.36 mm, and the ninth lens L9 may have negative focal power.

[0410] It can be understood that the first lens L1 to the ninth lens L9 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0411] Based on the data in Table 2a and Table 2b, some parameters of the camera module 300 of the second embodiment of the present application can be obtained, as shown in Table 2d below.

[0412] Table 2d Partial parameters of the camera module 300 of the second embodiment

[0413] f1 f2 f3 f4 f12 f123t f123s 56.96 -21.95 10.85 -12.37 -58.71 15.65 16.84 ft fs fm fse fte ΔG3 ΔG4 23.50 31.00 27.70 214.02 81.12 2.87 4.17 Redt Reds Redss IH IHs 0.39 0.03 0.23 12.53 6.27

[0414] It can be understood that the setting ranges of the relevant optical parameters in this embodiment can refer to the setting ranges of the relevant optical parameters in the first embodiment.

[0415] It can be understood that the focal length f1 of the first lens group G1 satisfies: f1=56.96mm, and the first lens group G1 can have positive focal power; the focal length f2 of the second lens group G2 satisfies: f2=-21.95mm, and the second lens group G2 can have negative focal power; the focal length f3 of the third lens group G3 satisfies: f3=10.85mm, and the third lens group G3 can have positive focal power; the focal length f4 of the fourth lens group G4 satisfies: f4=-12.37mm, and the fourth lens group G4 can have negative focal power.

[0416] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0417] The focal length ft at the telephoto end of the optical lens 10 and the focal length fs at the super-telephoto end of the optical lens 10 satisfy the following relationship: ft / fs = 0.76. It is understood that by limiting the ratio of the focal length ft at the telephoto end of the optical lens 10 to the focal length fs at the super-telephoto end of the optical lens 10 to 0.76, the zoom ratio and zoom magnification of the optical lens 10 can have a wider range of values, and the optical lens 10 has a wider field of view.

[0418] The optical lens 10 satisfies the following condition: fse / fte = 2.64. It is understood that by limiting fse / fte to 2.64, the zoom ratio of the optical lens 10 is appropriately selected, allowing the optical lens 10 to simultaneously achieve both shorter and longer focal lengths, facilitating shooting at both the super-telephoto and telephoto ends of the optical lens 10.

[0419] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction satisfy: ΔG4 / ΔG3=1.45. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction to the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction to be equal to 1.45, the movement distances of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the movement distances of the third lens group G3 and the fourth lens group G4 driven by the driving mechanism are relatively small, which is conducive to achieving a miniaturized configuration of the optical lens 10. At the same time, the structure of the driving mechanism is more simple.

[0420] The focal length f1 of the first lens group G1 and the focal length ft at the telephoto end of the optical lens 10 satisfy the following relationship: f1 / ft=2.47. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length ft at the telephoto end of the optical lens 10 to 2.47, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0421] The focal length ft at the telephoto end of the optical lens 10, the combined focal length f123t of the first lens group G1, the second lens group G2, and the third lens group G3 at the telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0422] |ft×(1 / f123t-1 / f12)|=1.90. It is understandable that by limiting |ft×(1 / f123t-1 / f12)| to 1.90, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0423] Among them, the focal length fs at the super telephoto end of the optical lens 10, the combined focal length f123s of the first lens group G1, the second lens group G2 and the third lens group G3 at the super telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0424] |fs×(1 / f123s−1 / f12)|=2.37. It can be understood that by limiting |fs×(1 / f123s−1 / f12)| to 2.37, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0425] The combined focal length f12 of the first lens group G1 and the second lens group G2 and the focal length f3 of the third lens group G3 satisfy:

[0426] f12 / f3=-5.41. It can be understood that by limiting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 to -5.41, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0427] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt = 0.39. It is understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to 0.39, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, thereby facilitating the optical lens 10 to photograph subjects at macro distances.

[0428] The magnification Reds of the super-telephoto end of the optical lens 10 at close range satisfies the following condition: Reds = 0.03. It is understood that by limiting the magnification Reds of the super-telephoto end of the optical lens 10 at close range to 0.03, the magnification Reds of the super-telephoto end of the optical lens 10 at close range is larger, which facilitates the optical lens 10 in photographing close-range subjects.

[0429] Among them, the magnification Redss of the ultra-long focal length end of the optical lens 10 in the macro state satisfies: Redss = 0.23. It can be understood that by limiting the magnification Redss of the ultra-long focal length end of the optical lens 10 in the macro state to be equal to 0.23, the magnification Redss of the ultra-long focal length end of the optical lens 10 in the macro state is more appropriate, and the optical lens 10 can achieve shooting with a large magnification for a relatively distant shooting object.

[0430] Among them, the refractive index Nd of the material of each lens of the optical lens 10 and the Abbe number Vd of each lens of the optical lens 10 satisfy:

[0431] 1.50 < Nd < 1.80, 20.4 < Vd < 81.56. It can be understood that by limiting the refractive index Nd of the material of each lens of the optical lens 10 to be within the range of 1.50 to 1.80, and limiting the Abbe number Vd of each lens of the optical lens 10 to be within the range of 20.4 to 81.56, the refractive index of each lens of the optical lens 10 is smaller and the Abbe number is larger, and the light transmittance of the lenses of each lens of the optical lens 10 is higher. In this way, the light penetration power of the lenses of each lens of the optical lens 10 is stronger, the optical quality of each lens of the optical lens 10 is higher, and the image captured by the optical lens 10 is clearer.

[0432] Among them, the focal length f2 of the second lens group G2 and the focal length fs of the ultra-long focal length end of the optical lens 10 satisfy: f2 / fs = -0.71. It can be understood that by limiting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-long focal length end of the optical lens 10 to be equal to -0.71, the assembly tolerance between the first lens group G1 to the fourth lens group G4 is increased, and the loss of the resolution of the optical lens 10 is reduced.

[0433] Among them, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 satisfy: f1 / f2 = -2.59. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 to be equal to -2.59, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 are reasonably allocated. Under this distribution of the optical power, by reasonably setting the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance among aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be realized.

[0434] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction, the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction, and the focal length fs of the optical lens 10 at the super-telephoto end satisfy: |(ΔG3+ΔG4) / fs|=0.23. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to 0.23, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, thereby facilitating a compact design of the optical lens 10.

[0435] Figure 12A FIG1 is a first simulation effect diagram of the telephoto end of the camera module 300 according to the second embodiment.

[0436] like Figure 12A As shown, when the camera module 300 is at the telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0437] Figure 12B FIG1 is a first simulation effect diagram of the super-telephoto end of the camera module 300 according to the second embodiment.

[0438] like Figure 12B As shown, when the camera module 300 is at the super telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0439] Figure 13A FIG2 is a second simulation effect diagram of the telephoto end of the camera module 300 according to the second embodiment.

[0440] like Figure 13A As shown, when the camera module 300 is at the telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0441] Figure 13B FIG2 is a second simulation effect diagram of the super-telephoto end of the camera module 300 according to the second embodiment.

[0442] like Figure 13B As shown, when the camera module 300 is at the super telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0443] Figure 14A FIG3 is a simulation effect diagram of the telephoto end of the camera module 300 according to the second embodiment.

[0444] like Figure 14A As shown, when the camera module 300 is at the telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 2%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0445] Figure 14B FIG3 is a simulation effect diagram of the super-telephoto end of the camera module 300 according to the second embodiment.

[0446] like Figure 14B As shown, when the camera module 300 is at the super telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 1%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0447] The third implementation method: Figure 15A yes Figure 1B FIG3 is a simplified schematic diagram of a portion of the structure of the camera module 300 in one embodiment. Figure 15B yes Figure 15A The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 15C yes Figure 15B The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figures 15A to 15C The camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0448] like Figures 15A to 15C As shown, the camera module 300 includes a first lens group G1, a second lens group G2, a stop 5 (attached), and a plurality of lens elements arranged in sequence from the object side to the image side. Figure 15A To the attached Figure 15C (not shown), the third lens group G3, the fourth lens group G4, the light switching element 6, the filter 30 and the image sensor 20.

[0449] Illustratively, the first lens group G1 includes a first lens L1 and a deflecting element 1a. The second lens group G2 includes a second lens L2. The third lens group G3 includes a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens L6. The fourth lens group G4 includes a seventh lens L7, an eighth lens L8, and a ninth lens L9.

[0450] For example, the first lens L1, the third lens L3, the fifth lens L5, the sixth lens L6, and the eighth lens L8 may all have positive refractive power, and the second lens L2, the fourth lens L4, the seventh lens L7, and the ninth lens L9 may all have negative refractive power.

[0451] like Figures 15A to 15C As shown, for example, the light-deflecting element 6 can be located on the image side of the fourth lens group G4. The light-deflecting element 6 can change the propagation direction of the optical axis from the second direction to a fourth direction. The fourth direction is different from both the first and second directions. In this case, the filter 30 and the image sensor 20 can be positioned facing the exit surface of the light-deflecting element 6.

[0452] For example, the light deflection element 6 can be a component that can realize a reflective function, such as an oblique prism, a right-angle prism, or a reflector. In other embodiments, the structure of the light deflection element 6 can also adopt other forms. This application does not limit this in detail.

[0453] For example, the optical deflection element 6 can deflect the optical axis in the second direction, thereby diverting the optical path to a certain angle. It is understood that the optical deflection element 6 can deflect the optical path, thereby increasing the optical length and improving the imaging quality of the optical lens 10. The optical deflection element 6 can also compress the optical dimensions, reducing the size of the optical lens 10 in the second direction, thereby facilitating the miniaturization of the optical lens 10 and the camera module 300.

[0454] For example, when the light-deflecting element 6 is an oblique prism, the light-deflecting element 6 can satisfy the following: 17.5° ≤ a ≤ 37.5°, where a is the minimum acute angle α within the light-deflecting element 6. For example, a can be 17.5°, 18.36°, 22°, 24°, 27.5°, 29.5°, 33°, 36.1°, or 37.5°. It will be appreciated that the minimum acute angle α of the light-deflecting element 6 has a suitable range of angle a, thereby ensuring a suitable angle between the third direction and the second direction. This facilitates reducing the size of the optical lens 10 in both the second and third directions, thereby facilitating a miniaturized design of the optical lens 10.

[0455] In other embodiments, the angle a of the minimum acute angle α of the light redirecting element 6 may also satisfy other ranges.

[0456] It is understandable that the Figure 15A To the attached Figure 15C The rectangle in the figure only schematically shows the relative position of the light-redirecting element 6 in the camera module 300. The actual shape and direction of the optical axis of the light-redirecting element 6 are not affected by the attached diagram. Figure 15A To the attached Figure 15C limit.

[0457] like Figures 15A to 15CAs shown, for example, when the optical lens 10 continuously zooms from the telephoto end to the intermediate section, and then continuously zooms to the super telephoto end, and focuses on the object at infinity, the first lens group G1 and the second lens group G2 are fixed lens groups, and the position of the first lens group G1 relative to the imaging plane in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can simultaneously move along the optical axis of the first sub-direction of the second direction, so that the distance between the second lens group G2 and the third lens group G3 is reduced, and the distance between the third lens group G3 and the fourth lens group G4 is reduced. The optical zoom ratio of the optical lens 10 can be in the range of 3X to 8X (including 3X and 8X). For example, the optical zoom ratio of the optical lens 10 can be 3X, 3.5X, 4X, 5X, 6.2X, 7X or 8X, etc. In other embodiments, the optical zoom ratio of the optical lens 10 can also meet other satisfying ranges.

[0458] For example, when the optical lens 10 is at a shorter focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both smaller. When the optical lens 10 is at a longer focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both larger. The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction is smaller than the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction. That is, the third lens group G3 and the fourth lens group G4 may satisfy the relationship: ΔG3<ΔG4.

[0459] Exemplarily, the focal length f1 of the first lens group G1 satisfies: f1>0, that is, the first lens group G1 may have positive refractive power. Exemplarily, the focal length f2 of the second lens group G2 may satisfy: f2<0, that is, the second lens group G2 may have negative refractive power. The focal length f3 of the third lens group G3 may satisfy: f3>0, that is, the third lens group G3 may have positive refractive power. The focal length f4 of the fourth lens group G4 may satisfy: f4<0, that is, the fourth lens group G4 may have negative refractive power.

[0460] For example, the deflecting element 1a can be a prism that changes the direction of propagation of the optical axis from a first direction to a second direction, deflecting light emitted by the first lens L1 before it enters the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a single two-dimensional plane, namely, the XZ plane.

[0461] For example, the first lens group G1 has an anti-shake compensation function, and can implement optical image stabilization of the optical lens 10. During the optical image stabilization process of the optical lens 10, the first lens group G1 can rotate around the first direction, the second direction, or the third direction.

[0462] Figure 16A yes Figure 15C The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 16B yes Figure 16A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figure 16A and Figure 16B The camera module 300 is in the close-range state at the super-telephoto end and the macro state at the super-telephoto end respectively.

[0463] like Figure 15C and Figure 16A As shown, for example, during zooming of the camera module 300 from the ultra-telephoto end to the ultra-telephoto end close-up state, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, while the fourth lens group G4 can move along the optical axis in the second sub-direction. At this time, the distance between the fourth lens group G4 and the third lens group G3 increases.

[0464] In some embodiments, during the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0465] like Figure 16A and Figure 16B As shown, for example, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis in the second sub-direction. In this case, the distance between the fourth lens group G4 and the third lens group G3 is further increased.

[0466] In some embodiments, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0467] It is understandable that the Figure 16A and attached Figure 16B The rectangle in the figure only schematically shows the relative position of the light-redirecting element 6 in the camera module 300. The actual shape and direction of the optical axis of the light-redirecting element 6 are not affected by the attached diagram. Figure 16A and attached Figure 16B limit.

[0468] Figure 17 yes Figure 15A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in another embodiment. It can be understood that Figure 17 The camera module 300 is in the macro state at the telephoto end.

[0469] like Figure 15A and Figure 17 As shown, for example, during zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, while the third lens group G3 can move along the optical axis in the first sub-direction. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0470] In some embodiments, during the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. This application does not limit this specifically.

[0471] It is understandable that the Figure 17 The rectangle in the figure only schematically shows the relative position of the light-redirecting element 6 in the camera module 300. The actual shape and direction of the optical axis of the light-redirecting element 6 are not affected by the attached diagram. Figure 17 limit.

[0479] The first lens L1, the third lens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6, the seventh lens L7, the eighth lens L8, and the ninth lens L9 are all made of resin, while the second lens L2, the deflecting element 1a, the light-deflecting element 6, and the filter 30 are all made of glass. It will be appreciated that the combination of resin and glass lenses enables the camera module 300 to have a lighter weight, greater durability, and superior optical performance.

[0480] In addition, the aspheric coefficients of each lens of the camera module 300 according to the third embodiment of the present application are shown in Table 3b below.

[0481] Table 3b Aspheric coefficients of each lens of the camera module 300 in the third embodiment

[0482]

[0483]

[0484] It is understood that among the 18 aspheric surfaces of the camera module 300 shown in Table 3a and Table 3b, the surface types z of all even-order and odd-order aspheric surfaces can be defined using, but not limited to, the following aspheric surface formula:

[0485]

[0486] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex curvature of the aspheric surface, K is the quadratic surface constant, A i Denotes the i-th order aspheric coefficient. Substituting the design parameters of the first lens L1 to the ninth lens L9 of the camera module 300 into the above aspheric formula, the object-side and image-side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 according to the third embodiment of the present application can be obtained.

[0487] Based on the data in Table 3a and Table 3b, some parameters of the camera module 300 of the third embodiment of the present application can be obtained, as shown in Table 3c below.

[0488] Table 3c Partial parameters of the camera module 300 of the third embodiment

[0489] fL1 fL2 fL3 fL4 fL5 fL6 fL7 fL8 fL9 35.00 -10.78 14.23 -29.53 14.00 37.63 -24.83 34.86 -17.58

[0490] It can be understood that the focal length fL1 of the first lens L1 satisfies: fL1 = 35.00 mm (millimeter), and the first lens L1 can have positive focal power; the focal length fL2 of the second lens L2 satisfies: fL2 = -10.78 mm, and the second lens L2 can have negative focal power; the focal length fL3 of the third lens L3 satisfies: fL3 = 14.23 mm, and the third lens L3 can have positive focal power; the focal length fL4 of the fourth lens L4 satisfies: fL4 = -29.53 mm, and the fourth lens L4 can have negative focal power; the focal length fL5 of the fifth lens L5 satisfies: fL5=14.00mm, and the fifth lens L5 may have positive focal power; the focal length fL6 of the sixth lens L6 satisfies: fL6=37.63mm, and the sixth lens L6 may have positive focal power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-24.83mm, and the seventh lens L7 may have negative focal power; the focal length fL8 of the eighth lens L8 satisfies: fL8=34.86mm, and the eighth lens L8 may have positive focal power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-17.58mm, and the ninth lens L9 may have negative focal power.

[0491] It can be understood that the combination of the first lens L1 through the ninth lens L9, forming a positive and negative lens structure, can better address aberrations such as chromatic aberration, providing the optical lens 10 with a higher degree of freedom and improved imaging quality. Based on the data in Tables 3a and 3b, some parameters of the camera module 300 according to the third embodiment of the present application can be obtained, as shown in Table 3d below.

[0492] Table 3d Partial parameters of the camera module 300 of the third embodiment

[0493]

[0494]

[0495] It can be understood that the setting ranges of the relevant optical parameters in this embodiment can refer to the setting ranges of the relevant optical parameters in the first embodiment.

[0496] It can be understood that the focal length f1 of the first lens group G1 satisfies: f1=35.00mm, and the first lens group G1 can have positive focal power; the focal length f2 of the second lens group G2 satisfies: f2=-10.78mm, and the second lens group G2 can have negative focal power; the focal length f3 of the third lens group G3 satisfies: f3=8.87mm, and the third lens group G3 can have positive focal power; the focal length f4 of the fourth lens group G4 satisfies: f4=-13.95mm, and the fourth lens group G4 can have negative focal power.

[0497] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0498] The focal length ft at the telephoto end of the optical lens 10 and the focal length fs at the super-telephoto end of the optical lens 10 satisfy the following equation: ft / fs = 0.74. It is understood that by limiting the ratio of the focal length ft at the telephoto end of the optical lens 10 to the focal length fs at the super-telephoto end of the optical lens 10 to 0.74, the zoom ratio and zoom magnification of the optical lens 10 can have a wider range of values, and the optical lens 10 has a wider field of view.

[0499] The optical lens 10 satisfies the following condition: fse / fte = 2.71. It is understood that by limiting fse / fte to 2.71, the zoom ratio of the optical lens 10 is appropriately selected, allowing the optical lens 10 to simultaneously achieve both shorter and longer focal lengths, facilitating shooting at both the super-telephoto and telephoto ends of the optical lens 10.

[0500] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction satisfy: ΔG4 / ΔG3=1.08. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction to the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction to be equal to 1.08, the respective movement distances of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the movement distances of the third lens group G3 and the fourth lens group G4 driven by the driving mechanism are relatively small, which is conducive to achieving a miniaturized configuration of the optical lens 10. At the same time, the structure of the driving mechanism is more simple.

[0501] The focal length f1 of the first lens group G1 and the focal length ft at the telephoto end of the optical lens 10 satisfy the following relationship: f1 / ft=1.51. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length ft at the telephoto end of the optical lens 10 to 1.51, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0502] The focal length ft at the telephoto end of the optical lens 10, the combined focal length f123t of the first lens group G1, the second lens group G2, and the third lens group G3 at the telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0503] |ft×(1 / f123t-1 / f12)|=2.48. It can be understood that by limiting |ft×(1 / f123t-1 / f12)| to 2.48, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0504] Among them, the focal length fs at the super telephoto end of the optical lens 10, the combined focal length f123s of the first lens group G1, the second lens group G2 and the third lens group G3 at the super telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0505] |fs×(1 / f123s−1 / f12)|=2.99. It can be understood that by limiting |fs×(1 / f123s−1 / f12)| to 2.99, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0506] The combined focal length f12 of the first lens group G1 and the second lens group G2 and the focal length f3 of the third lens group G3 satisfy:

[0507] f12 / f3=-3.38. It can be understood that by limiting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 to -3.38, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0508] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt = 0.31. It is understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to 0.31, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, thereby facilitating the optical lens 10 to photograph subjects at macro distances.

[0509] The magnification Reds of the super-telephoto end of the optical lens 10 at close range satisfies the following condition: Reds = 0.03. It is understood that by limiting the magnification Reds of the super-telephoto end of the optical lens 10 at close range to 0.03, the magnification Reds of the super-telephoto end of the optical lens 10 at close range is larger, which facilitates the optical lens 10 in photographing close-range subjects.

[0510] Among them, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state satisfies: Redss = 0.18. It can be understood that by restricting the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state to be equal to 0.18, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state is more appropriate, and the optical lens 10 can achieve shooting with a larger magnification for a relatively distant shooting object.

[0511] Among them, the refractive index Nd of the material of each lens of the optical lens 10 and the Abbe number Vd of each lens of the optical lens 10 satisfy:

[0512] 1.44 < Nd < 1.91, 19.4 < Vd < 95.1. It can be understood that by restricting the refractive index Nd of the material of each lens of the optical lens 10 to be within the range of 1.44 to 1.91, and restricting the Abbe number Vd of each lens of the optical lens 10 to be within the range of 19.4 to 95.1, the refractive index of each lens of the optical lens 10 is smaller and the Abbe number is larger, and the light transmittance of the lenses of each lens of the optical lens 10 is higher. In this way, the light penetration ability of the lenses of each lens of the optical lens 10 is stronger, the optical quality of each lens of the optical lens 10 is higher, and the image captured by the optical lens 10 is clearer.

[0513] Among them, the focal length f2 of the second lens group G2 and the focal length fs of the ultra-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.34. It can be understood that by restricting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-telephoto end of the optical lens 10 to be equal to -0.34, the assembly tolerance between the first lens group G1 to the fourth lens group G4 is increased, and the loss of the resolution of the optical lens 10 is reduced.

[0514] Among them, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 satisfy: f1 / f2 = -3.25. It can be understood that by restricting the ratio of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 to be equal to -3.25, the focal lengths f1 of the first lens group G1 and f2 of the second lens group G2 are reasonably allocated. Under this distribution of optical power, by reasonably setting the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance among aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be realized.

[0515] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction, the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction, and the focal length fs of the optical lens 10 at the super-telephoto end satisfy: |(ΔG3+ΔG4) / fs|=0.21. It will be appreciated that by limiting |(ΔG3+ΔG4) / fs| to 0.21, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, thereby facilitating a compact design of the optical lens 10.

[0516] Figure 18A FIG1 is a first simulation effect diagram of the telephoto end of the camera module 300 according to the third embodiment.

[0517] like Figure 18A As shown, when the camera module 300 is at the telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0518] Figure 18B FIG1 is a simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the third embodiment.

[0519] like Figure 18B As shown, when the camera module 300 is at the super telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0520] Figure 19A FIG2 is a second simulation effect diagram of the telephoto end of the camera module 300 according to the third embodiment.

[0521] like Figure 19A As shown, when the camera module 300 is at the telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0522] Figure 19B FIG2 is a second simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the third embodiment.

[0523] like Figure 19B As shown, when the camera module 300 is at the super telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0524] Figure 20A FIG3 is a third simulation effect diagram of the telephoto end of the camera module 300 according to the third embodiment.

[0525] like Figure 20A As shown, when the camera module 300 is at the telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 3%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0526] Figure 20B FIG3 is a third simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the third embodiment.

[0527] like Figure 20B As shown, when the camera module 300 is at the super telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 1.5%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0528] Figure 21 yes Figure 15A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in another embodiment.

[0529] like Figure 21 As shown, illustratively, the light-returning element 6 may be a right-angle prism, and the light passing through the first lens group G1 to the fourth lens group G4 may be reflected at least once on the light-returning element 6 .

[0530] Figure 22 yes Figure 15A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in yet another embodiment.

[0531] like Figure 22 As shown, illustratively, the light-redirecting element 6 may be an oblique prism, and the light passing through the first lens group G1 to the fourth lens group G4 may be reflected at least twice on the light-redirecting element 6 .

[0532] The fourth implementation method: Figure 23A yes Figure 1B FIG4 is a simplified schematic diagram of a portion of the structure of the camera module 300 in one embodiment. Figure 23B yes Figure 23A The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 23C yes Figure 23B The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figures 23A to 23C The camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0533] like Figures 23A to 23CAs shown, exemplarily, the camera module 300 includes a first lens group G1, a second lens group G2, an aperture 5, a third lens group G3, a fourth lens group G4, a filter 30 and an image sensor 20 arranged in sequence from the object side to the image side.

[0534] Exemplarily, the first lens group G1 includes a first lens L1, a second lens L2, and a deflecting element 1a. The second lens group G2 includes a third lens L3 and a fourth lens L4. The third lens group G3 includes a fifth lens L5, a sixth lens L6, a seventh lens L7, and an eighth lens L8. The fourth lens group G4 includes a ninth lens L9, a tenth lens L10, and an eleventh lens L11.

[0535] For example, the first lens L1, the deflecting element 1a, the fourth lens L4, the fifth lens L5, the eighth lens L8, and the ninth lens L9 may all have positive refractive power, while the second lens L2, the third lens L3, the sixth lens L6, the seventh lens L7, the tenth lens L10, and the eleventh lens L11 may all have negative refractive power.

[0536] like Figures 23A to 23C As shown, for example, when the optical lens 10 continuously zooms from the telephoto end to the intermediate section, and then continuously zooms to the super telephoto end, and focuses on the object at infinity, the first lens group G1 and the second lens group G2 are fixed lens groups, and the position of the first lens group G1 relative to the imaging plane in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can simultaneously move along the optical axis of the first sub-direction of the second direction, so that the distance between the second lens group G2 and the third lens group G3 is reduced, and the distance between the third lens group G3 and the fourth lens group G4 is reduced. The optical zoom ratio of the optical lens 10 can be in the range of 3X to 8X (including 3X and 8X). For example, the optical zoom ratio of the optical lens 10 can be 3X, 3.5X, 4X, 5X, 6.2X, 7X or 8X, etc. In other embodiments, the optical zoom ratio of the optical lens 10 can also meet other satisfying ranges.

[0537] For example, when the optical lens 10 is at a shorter focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both smaller. When the optical lens 10 is at a longer focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both larger. The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction is smaller than the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction. That is, the third lens group G3 and the fourth lens group G4 may satisfy the relationship: ΔG3<ΔG4.

[0538] Exemplarily, the focal length f1 of the first lens group G1 satisfies: f1>0, that is, the first lens group G1 may have positive refractive power. Exemplarily, the focal length f2 of the second lens group G2 may satisfy: f2<0, that is, the second lens group G2 may have negative refractive power. The focal length f3 of the third lens group G3 may satisfy: f3>0, that is, the third lens group G3 may have positive refractive power. The focal length f4 of the fourth lens group G4 may satisfy: f4<0, that is, the fourth lens group G4 may have negative refractive power.

[0539] For example, the deflecting element 1a can be a prism that changes the direction of propagation of the optical axis from a first direction to a second direction, deflecting light emitted by the first lens L1 and the second lens L2 before it enters the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a single two-dimensional plane, namely, the XZ plane.

[0540] For example, the first lens group G1 has an anti-shake compensation function, and can implement optical image stabilization of the optical lens 10. During the optical image stabilization process of the optical lens 10, the first lens group G1 can rotate around the first direction, the second direction, or the third direction.

[0541] Figure 24A yes Figure 23C The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 24B yes Figure 24A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figure 24A and Figure 24B The camera module 300 is in the close-range state at the super-telephoto end and the macro state at the super-telephoto end respectively.

[0542] like Figure 23C and Figure 24A As shown, for example, during zooming of the camera module 300 from the ultra-telephoto end to the ultra-telephoto end close-up state, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, while the fourth lens group G4 can move along the optical axis in the second sub-direction. At this time, the distance between the fourth lens group G4 and the third lens group G3 increases.

[0543] In some embodiments, during the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0544] like Figure 24A and Figure 24B As shown, for example, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis in the second sub-direction. In this case, the distance between the fourth lens group G4 and the third lens group G3 is further increased.

[0555] The first lens L1, the second lens L2, the third lens L3, the fifth lens L5, the seventh lens L7, the eighth lens L8, the ninth lens L9, and the eleventh lens L11 are all made of resin, while the deflecting element 1a, the fourth lens L4, the sixth lens L6, the tenth lens L10, and the filter 30 are all made of glass. It will be appreciated that the combination of resin and glass lenses enables the camera module 300 to have a lighter weight, greater durability, and superior optical performance.

[0556] In addition, the aspheric coefficients of each lens of the camera module 300 according to the fourth embodiment of the present application are shown in Table 4b below.

[0557] Table 4b Aspheric coefficients of each lens of the camera module 300 in the fourth embodiment

[0558]

[0559]

[0560] It is understood that among the 23 aspheric surfaces of the camera module 300 shown in Table 4a and Table 4b, the surface types z of all even-order and odd-order aspheric surfaces can be defined using, but not limited to, the following aspheric surface formula:

[0561]

[0562] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex curvature of the aspheric surface, K is the quadratic surface constant, A i represents the i-th-order aspheric coefficient. Substituting the design parameters of the first through eleventh lenses L1 through L11 of the camera module 300 and the deflecting element 1a into the above aspheric formula yields the object-side and image-side surface shapes of the first through eleventh lenses L1 through L11 of the camera module 300, as well as the image-side surface shape of the deflecting element 1a, in accordance with the fourth embodiment of the present application.

[0563] Based on the data in Table 4a and Table 4b, some parameters of the camera module 300 of the fourth embodiment of the present application can be obtained, as shown in Table 4c below.

[0564] Table 4c Partial parameters of the camera module 300 of the fourth embodiment

[0565] fL1 fL2 f1a fL3 fL4 fL5 45.10 -56.33 141.06 -12.97 63.78 8.14 fL6 fL7 fL8 fL9 fL10 fL11 -23.22 -26.49 17.67 32.07 -30.54 -27.57

[0566] Wherein, f1a may represent the focal length of the folding element 1a, fL10 may represent the focal length of the tenth lens L10, and fL11 may represent the focal length of the eleventh lens L11.

[0567] It can be understood that the focal length fL1 of the first lens L1 satisfies: fL1 = 45.10 mm (millimeter), and the first lens L1 can have positive focal power; the focal length fL2 of the second lens L2 satisfies: fL2 = -56.33 mm, and the second lens L2 can have negative focal power; the focal length f1a of the folding element 1a satisfies: f1a = 141.06 mm, and the folding element 1a can have positive focal power; the focal length fL3 of the third lens L3 satisfies: fL3 = -12.97 mm, and the third lens L3 can have negative focal power; the focal length fL4 of the fourth lens L4 satisfies: fL4 = 63.78 mm, and the fourth lens L4 can have positive focal power; the focal length fL5 of the fifth lens L5 satisfies: fL5 = 8.14 mm, and the fifth lens L5 can have positive focal power. The focal length fL6 of the sixth lens L6 satisfies the following: fL6 = -23.22 mm, and the sixth lens L6 may have negative focal power. The focal length fL7 of the seventh lens L7 satisfies the following: fL7 = -26.49 mm, and the seventh lens L7 may have negative focal power. The focal length fL8 of the eighth lens L8 satisfies the following: fL8 = 17.67 mm, and the eighth lens L8 may have positive focal power. The focal length fL9 of the ninth lens L9 satisfies the following: fL9 = 32.07 mm, and the ninth lens L9 may have positive focal power. The focal length fL10 of the tenth lens L10 satisfies the following: fL10 = -30.54 mm, and the tenth lens L10 may have negative focal power. The focal length fL11 of the eleventh lens L11 satisfies the following: fL11 = -27.57 mm, and the tenth lens L10 may have negative focal power.

[0568] It can be understood that the first lens L1 to the eleventh lens L11 and the folding element 1a are used together to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0569] Based on the data in Table 4a and Table 4b, some parameters of the camera module 300 of the fourth embodiment of the present application can be obtained, as shown in Table 4d below.

[0570] Table 4d Partial parameters of the camera module 300 of the fourth embodiment

[0571] f1 f2 f3 f4 f12 f123t f123s 77.43 -15.30 10.35 -25.35 -32.01 17.34 24.80 ft fs fm fse fte ΔG3 ΔG4 20.90 36.23 28.93 195.94 113.03 5.74 7.19 Redt Reds Redss IH IHs 0.25 0.04 0.18 8.00 8.00

[0572] It can be understood that the setting ranges of the relevant optical parameters in this embodiment can refer to the setting ranges of the relevant optical parameters in the first embodiment.

[0573] It can be understood that the focal length f1 of the first lens group G1 satisfies: f1=77.43mm, and the first lens group G1 can have positive focal power; the focal length f2 of the second lens group G2 satisfies: f2=-15.30mm, and the second lens group G2 can have negative focal power; the focal length f3 of the third lens group G3 satisfies: f3=10.35mm, and the third lens group G3 can have positive focal power; the focal length f4 of the fourth lens group G4 satisfies: f4=-25.35mm, and the fourth lens group G4 can have negative focal power.

[0574] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0575] The focal length ft at the telephoto end of the optical lens 10 and the focal length fs at the super-telephoto end of the optical lens 10 satisfy the following equation: ft / fs = 0.58. It is understood that by limiting the ratio of the focal length ft at the telephoto end of the optical lens 10 to the focal length fs at the super-telephoto end of the optical lens 10 to 0.58, the zoom ratio and zoom magnification of the optical lens 10 can have a wider range of values, and the optical lens 10 has a wider field of view.

[0576] The optical lens 10 satisfies the following condition: fse / fte = 1.73. It is understood that by limiting fse / fte to 1.73, the zoom ratio of the optical lens 10 is appropriately selected, allowing the optical lens 10 to simultaneously achieve both shorter and longer focal lengths, facilitating shooting at both the super-telephoto and telephoto ends of the optical lens 10.

[0577] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction satisfy: ΔG4 / ΔG3=1.25. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction to the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction to be equal to 1.25, the movement distances of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the movement distances of the third lens group G3 and the fourth lens group G4 driven by the driving mechanism are relatively small, which is conducive to achieving a miniaturized configuration of the optical lens 10. At the same time, the structure of the driving mechanism is more simple.

[0578] The focal length f1 of the first lens group G1 and the focal length ft at the telephoto end of the optical lens 10 satisfy the following relationship: f1 / ft=3.70. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length ft at the telephoto end of the optical lens 10 to 3.70, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0579] The focal length ft at the telephoto end of the optical lens 10, the combined focal length f123t of the first lens group G1, the second lens group G2, and the third lens group G3 at the telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0580] |ft×(1 / f123t-1 / f12)|=1.858. It can be understood that by limiting |ft×(1 / f123t-1 / f12)| to 1.858, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0581] Among them, the focal length fs at the super telephoto end of the optical lens 10, the combined focal length f123s of the first lens group G1, the second lens group G2 and the third lens group G3 at the super telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0582] |fs×(1 / f123s−1 / f12)|=2.59. It can be understood that by limiting |fs×(1 / f123s−1 / f12)| to 2.59, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0583] The combined focal length f12 of the first lens group G1 and the second lens group G2 and the focal length f3 of the third lens group G3 satisfy:

[0584] f12 / f3=-3.09. It can be understood that by limiting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 to -3.09, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0585] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt = 0.25. It is understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to 0.25, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, thereby facilitating the optical lens 10 to photograph subjects at macro distances.

[0586] Among them, the magnification Reds of the ultra-telephoto end of the optical lens 10 in the near-distance state satisfies: Reds = 0.04. It can be understood that by restricting the magnification Reds of the ultra-telephoto end of the optical lens 10 in the near-distance state to be 0.04, the magnification Reds of the ultra-telephoto end of the optical lens 10 in the near-distance state is relatively large, which is conducive to achieving the shooting of the shooting object in the near distance by the optical lens 10.

[0587] Among them, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state satisfies: Redss = 0.18. It can be understood that by restricting the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state to be equal to 0.18, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state is relatively appropriate, and the optical lens 10 can achieve shooting with a relatively large magnification for a relatively distant shooting object.

[0588] Among them, the refractive index Nd of the material of each lens of the optical lens 10 and the Abbe number Vd of each lens of the optical lens 10 satisfy:

[0589] 1.44 < Nd < 2.09, 17.13 < Vd < 84.4. It can be understood that by restricting the refractive index Nd of the material of each lens of the optical lens 10 to be within the range of 1.44 to 2.09, and restricting the Abbe number Vd of each lens of the optical lens 10 to be within the range of 17.13 to 84.4, the refractive index of each lens of the optical lens 10 is relatively small and the Abbe number is relatively large, and the light transmittance of each lens of the optical lens 10 is relatively high. In this way, the light penetration ability of each lens of the optical lens 10 is relatively strong, the optical quality of each lens of the optical lens 10 is relatively high, and the image captured by the optical lens 10 is clearer.

[0590] Among them, the focal length f2 of the second lens group G2 and the focal length fs of the ultra-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.42. It can be understood that by restricting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-telephoto end of the optical lens 10 to be equal to -0.42, the assembly tolerance between the first lens group G1 and the fourth lens group G4 is increased, and the loss of the resolution of the optical lens 10 is reduced.

[0591] The focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 satisfy the following equation: f1 / f2 = -5.06. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 to -5.06, a more reasonable distribution of the focal lengths f1 and f2 of the first lens group G1 and the second lens group G2 is achieved. With this distribution of optical power, by properly configuring the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance between aberrations, volume, cost, thermal reliability, and other factors can be achieved, enabling a wide range of continuous zoom ratios.

[0592] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction, the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction, and the focal length fs of the optical lens 10 at the super-telephoto end satisfy: |(ΔG3+ΔG4) / fs|=0.36. It will be appreciated that by limiting |(ΔG3+ΔG4) / fs| to 0.36, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, thereby facilitating a compact design of the optical lens 10.

[0593] Figure 26A FIG1 is a first simulation effect diagram of the telephoto end of the camera module 300 according to the fourth embodiment.

[0594] like Figure 26A As shown, when the camera module 300 is at the telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0602] like Figure 28A As shown, when the camera module 300 is at the telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 2%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0603] Figure 28B FIG3 is a third simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the fourth embodiment.

[0604] like Figure 28B As shown, when the camera module 300 is at the super telephoto end, the optical distortion ratio of the camera module 300 at different image heights is less than 0.5%, which can ensure that there is no obvious deformation of the picture, the degree of optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0605] For example, the incident surface of the deflecting element 1a may be convex, and the incident surface of the deflecting element 1a may be disposed facing the second lens L2. The exit surface of the deflecting element 1a may be concave, and the exit surface of the deflecting element 1a may be disposed facing the third lens L3.

[0606] In some embodiments, the incident surface of the deflecting element 1a can be a plane, and the second lens L2 can be fixedly connected to the incident surface of the deflecting element 1a. In other embodiments, the second lens L2 can be integrally formed with the deflecting element 1a. This application does not limit this in detail.

[0607] In some embodiments, the incident surface of the deflecting element 1a may also be a plane, and the first lens group G1 may further include one or more lenses, wherein the incident surface of the one or more lenses may be convex. The exit surface of the one or more lenses may be fixedly connected to the incident surface of the deflecting element 1a. In other embodiments, the one or more lenses may be integrally formed with the deflecting element 1a. This application does not limit this in detail.

[0608] In some embodiments, the exit surface of the deflecting element 1a may also be a plane, and the first lens group G1 may further include one or more lenses, wherein the exit surface of one or more lenses may be concave. The incident surface of the one or more lenses may be fixedly connected to the exit surface of the deflecting element 1a.

[0609] The fifth implementation method: Figure 29A yes Figure 1B The camera module 300 shown in FIG. Figure 5 . Figure 29B yes Figure 29A The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 29C yes Figure 29B The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figures 29A to 29C The camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0610] like Figures 29A to 29C As shown, the camera module 300 includes a first lens group G1, a second lens group G2, a stop 5 (attached), and a plurality of lens elements arranged in sequence from the object side to the image side. Figure 29A To the attached Figure 29C (not shown), the third lens group G3, the fourth lens group G4, the filter 30 and the image sensor 20.

[0611] Illustratively, the first lens group G1 includes a first lens L1 and a deflecting element 1a. The second lens group G2 includes a second lens L2. The third lens group G3 includes a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens L6. The fourth lens group G4 includes a seventh lens L7, an eighth lens L8, and a ninth lens L9.

[0612] For example, the first lens L1, the third lens L3, the sixth lens L6, and the eighth lens L8 may all have positive refractive power, and the second lens L2, the fourth lens L4, the fifth lens L5, the seventh lens L7, and the ninth lens L9 may all have negative refractive power.

[0613] like Figures 29A to 29CAs shown, for example, when the optical lens 10 continuously zooms from the telephoto end to the intermediate section, and then continuously zooms to the super telephoto end, and focuses on the object at infinity, the first lens group G1 and the second lens group G2 are fixed lens groups, and the position of the first lens group G1 relative to the imaging plane in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can simultaneously move along the optical axis of the first sub-direction of the second direction, so that the distance between the second lens group G2 and the third lens group G3 is reduced, and the distance between the third lens group G3 and the fourth lens group G4 is reduced. The optical zoom ratio of the optical lens 10 can be in the range of 3X to 8X (including 3X and 8X). For example, the optical zoom ratio of the optical lens 10 can be 3X, 3.5X, 4X, 5X, 6.2X, 7X or 8X, etc. In other embodiments, the optical zoom ratio of the optical lens 10 can also meet other satisfying ranges.

[0614] For example, when the optical lens 10 is at a shorter focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both smaller. When the optical lens 10 is at a longer focal length, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are both larger. The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction is smaller than the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction. That is, the third lens group G3 and the fourth lens group G4 may satisfy the relationship: ΔG3<ΔG4.

[0615] Exemplarily, the focal length f1 of the first lens group G1 satisfies: f1>0, that is, the first lens group G1 may have positive refractive power. Exemplarily, the focal length f2 of the second lens group G2 may satisfy: f2<0, that is, the second lens group G2 may have negative refractive power. The focal length f3 of the third lens group G3 may satisfy: f3>0, that is, the third lens group G3 may have positive refractive power. The focal length f4 of the fourth lens group G4 may satisfy: f4<0, that is, the fourth lens group G4 may have negative refractive power.

[0616] For example, the deflecting element 1a can be a reflector that changes the direction of propagation of the optical axis from a first direction to a second direction, deflecting light emitted by the first lens L1 before it enters the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a single two-dimensional plane, namely, the XZ plane.

[0617] For example, the first lens group G1 has an anti-shake compensation function, and can implement optical image stabilization of the optical lens 10. During the optical image stabilization process of the optical lens 10, the first lens group G1 can rotate around the first direction, the second direction, or the third direction.

[0618] Figure 30A yes Figure 29C The illustrated diagram is a simplified schematic diagram of a portion of the structure of a camera module 300 in one embodiment. Figure 30B yes Figure 30A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in one embodiment. It is understood that Figure 30A and Figure 30B The camera module 300 is in the close-range state at the super-telephoto end and the macro state at the super-telephoto end respectively.

[0619] like Figure 29C and Figure 30A As shown, for example, during zooming of the camera module 300 from the ultra-telephoto end to the ultra-telephoto end at close range, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, while the third lens group G3 can move along the optical axis in the first sub-direction. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0620] In some embodiments, during the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the ultra-telephoto end to the close-up state at the ultra-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0621] like Figure 30A and Figure 30B As shown, for example, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the optical axis in the second sub-direction. In this case, the distance between the fourth lens group G4 and the third lens group G3 is further increased.

[0622] In some embodiments, during the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can all be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the close-up state at the super-telephoto end to the macro state at the super-telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. This application does not limit this in detail.

[0623] Figure 31 yes Figure 29A The camera module 300 shown is a simplified schematic diagram of a portion of the structure in another embodiment. It can be understood that Figure 31 The camera module 300 is in the macro state at the telephoto end.

At this time, the distance between the third lens group G3 and the second lens group G2 decreases, while the distance between the third lens group G3 and the fourth lens group G4 increases.

[0625] In some embodiments, during the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 can all be fixed lens groups, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. In other embodiments, the interior of the camera module 300 has sufficient space, the spacing between the second lens group G2 and the third lens group G3 is large, and the spacing between the fourth lens group G4 and the filter 30 is large. During the zooming process of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1 and the second lens group G2 can all be fixed lens groups, the third lens group G3 can move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. This application does not limit this specifically.

[0626] For example, some design parameters of the camera module 300 according to the fifth embodiment of the present application are shown in Table 5a below.

[0627] Table 5a Partial design parameters of each lens of the camera module 300 of the fifth embodiment

[0628]

[0629]

[0630] It can be understood that in Table 5a, OBJ can represent the object side surface of the camera module 300; S1 and S2 can represent the object side surface and image side surface of the first lens L1 respectively; S3 and S4 can represent the object side surface and image side surface of the folding element 1a respectively; S5 can represent the aperture 5; S6 and S7 can represent the object side surface and image side surface of the second lens L2 respectively; S8 and S9 can represent the object side surface and image side surface of the third lens L3 respectively; S10 and S11 can represent the object side surface and image side surface of the fourth lens L4 respectively; S12 and S 13 can respectively represent the object-side surface and the image-side surface of the fifth lens L5; S14 and S15 can respectively represent the object-side surface and the image-side surface of the sixth lens L6; S16 and S17 can respectively represent the object-side surface and the image-side surface of the seventh lens L7; S18 and S19 can respectively represent the object-side surface and the image-side surface of the eighth lens L8; S20 and S21 can respectively represent the object-side surface and the image-side surface of the ninth lens L9; S22 and S23 can respectively represent the object-side surface and the image-side surface of the filter 30; S24 can represent the imaging surface of the camera module 300.

[0631] In addition, the thickness of OBJ refers to the distance between the photographed object and the object side surface of the camera module 300. The thickness of S1 refers to the distance between the object side surface of the first lens L1 and the image side surface of the first lens L1. The thickness of S2 refers to the distance between the image side surface of the first lens L1 and the object side surface of the refracting element 1a.

The thickness of S10 refers to the distance between the image-side surface of the third lens L3 and the object-side surface of the fourth lens group G4. The thickness of S11 refers to the distance between the object-side surface of the fourth lens L4 and the image-side surface of the fourth lens L4. The thickness of S12 refers to the distance between the image-side surface of the fourth lens L4 and the object-side surface of the fifth lens L5. The thickness of S13 refers to the distance between the object-side surface of the fifth lens L5 and the image-side surface of the fifth lens L5. The thickness of S14 refers to the distance between the image-side surface of the fifth lens L5 and the object-side surface of the sixth lens L6. The thickness of S15 refers to the distance between the object-side surface of the sixth lens L6 and the image-side surface of the sixth lens L6. The thickness of S16 refers to the distance between the image-side surface of the sixth lens L6 and the object-side surface of the seventh lens L7. The thickness of S17 refers to the distance between the object-side surface of the seventh lens L7 and the image-side surface of the seventh lens L7. The thickness of S18 refers to the distance between the image-side surface of the seventh lens L7 and the object-side surface of the eighth lens L8.

The thickness of S24 refers to the distance between the image-side surface of the optical filter 30 and the imaging surface.

[0632] The first lens L1, the third lens L3, the fourth lens L4, the fifth lens L5, the seventh lens L7, the eighth lens L8, the ninth lens L9, and the filter 30 are all made of resin, while the second lens L2, the deflecting element 1a, and the sixth lens L6 are all made of glass. It will be appreciated that the combination of resin and glass lenses enables the camera module 300 to have a lighter weight, greater durability, and superior optical performance.

[0633] In addition, the aspheric coefficients of each lens of the camera module 300 of the fifth embodiment of the present application are shown in Table 5b below.

[0634] Table 5b Aspheric coefficients of each lens of the camera module 300 in the fifth embodiment

[0635]

[0636]

[0637] It is understood that among the 18 aspheric surfaces of the camera module 300 shown in Table 5a and Table 5b, the surface types z of all even-order and odd-order aspheric surfaces can be defined using, but not limited to, the following aspheric surface formula:

[0638]

[0639] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex curvature of the aspheric surface, K is the quadratic surface constant, A i Denotes the i-th order aspheric coefficient. Substituting the design parameters of the first lens L1 to the ninth lens L9 of the camera module 300 into the above aspheric formula, the object-side and image-side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 according to the fifth embodiment of the present application can be obtained.

[0640] Based on the data in Table 5a and Table 5b, some parameters of the camera module 300 of the fifth embodiment of the present application can be obtained, as shown in Table 5c below.

[0641] Table 5c Partial parameters of the camera module 300 of the fifth embodiment

[0642] fL1 fL2 fL3 fL4 fL5 fL6 fL7 fL8 fL9 49.41 -17.65 15.24 -43.34 -743.83 16.57 -23.62 19.43 -12.53

[0643] It can be understood that the focal length fL1 of the first lens L1 satisfies: fL1=49.41 mm (millimeter), and the first lens L1 can have positive focal power; the focal length fL2 of the second lens L2 satisfies: fL2=-17.65 mm, and the second lens L2 can have negative focal power; the focal length fL3 of the third lens L3 satisfies: fL3=15.24 mm, and the third lens L3 can have positive focal power; the focal length fL4 of the fourth lens L4 satisfies: fL4=-43.34 mm, and the fourth lens L4 can have negative focal power; the focal length fL5 of the fifth lens L5 satisfies: f L5=-743.83 mm, and the fifth lens L5 may have negative focal power; the focal length fL6 of the sixth lens L6 satisfies: fL6=16.57 mm, and the sixth lens L6 may have positive focal power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-23.62 mm, and the seventh lens L7 may have negative focal power; the focal length fL8 of the eighth lens L8 satisfies: fL8=19.43 mm, and the eighth lens L8 may have positive focal power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-12.53 mm, and the ninth lens L9 may have negative focal power.

[0644] It can be understood that the combination of the first lens L1 through the ninth lens L9, forming a positive and negative lens structure, can better address aberrations such as chromatic aberration, providing the optical lens 10 with a higher degree of freedom and improved imaging quality. Based on the data in Tables 5a and 5b, some parameters of the camera module 300 according to the fifth embodiment of the present application can be obtained, as shown in Table 5d below.

[0645] Table 5d Partial parameters of the camera module 300 of the fifth embodiment

[0646] f1 f2 f3 f4 f12 f123t f123s 49.41 -17.65 12.07 -13.65 -51.66 16.02 20.69 ft fs fm fse fte ΔG3 ΔG4 23.50 47.00 33.14 162.24 81.12 8.80 11.00 Redt Reds Redss IH IHs 0.20 0.05 0.37 12.53 12.53

[0647] It can be understood that the setting ranges of the relevant optical parameters in this embodiment can refer to the setting ranges of the relevant optical parameters in the first embodiment.

[0648] It can be understood that the focal length f1 of the first lens group G1 satisfies: f1=49.41 mm, and the first lens group G1 can have positive focal power; the focal length f2 of the second lens group G2 satisfies: f2=-17.65 mm, and the second lens group G2 can have negative focal power; the focal length f3 of the third lens group G3 satisfies: f3=12.07 mm, and the third lens group G3 can have positive focal power; the focal length f4 of the fourth lens group G4 satisfies: f4=-13.65 mm, and the fourth lens group G4 can have negative focal power.

[0649] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in combination to form a positive and negative lens combination structure, which can better solve aberration problems such as chromatic aberration, and the optical lens 10 has a higher degree of freedom and better imaging quality.

[0650] The focal length ft at the telephoto end of the optical lens 10 and the focal length fs at the super-telephoto end of the optical lens 10 satisfy the following relationship: ft / fs = 0.50. It will be appreciated that by limiting the ratio of the focal length ft at the telephoto end of the optical lens 10 to the focal length fs at the super-telephoto end of the optical lens 10 to 0.50, the zoom ratio and zoom magnification of the optical lens 10 can have a wider range of values, and the optical lens 10 has a wider field of view.

[0651] The optical lens 10 satisfies the following condition: fse / fte = 2.00. It is understood that by limiting fse / fte to 2.00, the zoom ratio of the optical lens 10 is appropriately selected, allowing the optical lens 10 to simultaneously achieve both shorter and longer focal lengths, facilitating shooting at both the super-telephoto and telephoto ends of the optical lens 10.

[0652] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction satisfy: ΔG4 / ΔG3=1.25. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction to the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction to be equal to 1.25, the movement distances of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the movement distances of the third lens group G3 and the fourth lens group G4 driven by the driving mechanism are relatively small, which is conducive to achieving a miniaturized configuration of the optical lens 10. At the same time, the structure of the driving mechanism is more simple.

[0653] The focal length f1 of the first lens group G1 and the focal length ft at the telephoto end of the optical lens 10 satisfy the following relationship: f1 / ft=2.10. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 to the focal length ft at the telephoto end of the optical lens 10 to 2.10, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0654] The focal length ft at the telephoto end of the optical lens 10, the combined focal length f123t of the first lens group G1, the second lens group G2, and the third lens group G3 at the telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0655] |ft×(1 / f123t-1 / f12)|=1.922. It can be understood that by limiting |ft×(1 / f123t-1 / f12)|

[0656] It is equal to 1.922, which can accurately control the focus of the optical lens 10 and improve the focusing effect of the optical lens 10.

[0657] Among them, the focal length fs at the super telephoto end of the optical lens 10, the combined focal length f123s of the first lens group G1, the second lens group G2 and the third lens group G3 at the super telephoto end of the optical lens 10, and the combined focal length f12 of the first lens group G1 and the second lens group G2 satisfy:

[0658] |fs×(1 / f123s−1 / f12)|=3.18. It can be understood that by limiting |fs×(1 / f123s−1 / f12)| to 3.18, the focus of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0659] The combined focal length f12 of the first lens group G1 and the second lens group G2 and the focal length f3 of the third lens group G3 satisfy:

[0660] f12 / f3=-4.28. It can be understood that by limiting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 to -4.28, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0661] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt = 0.20. It is understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to 0.20, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, thereby facilitating the optical lens 10 to photograph subjects at macro distances.

[0662] The magnification Reds of the super-telephoto end of the optical lens 10 at close range satisfies the following condition: Reds = 0.005. It is understood that by limiting the magnification Reds of the super-telephoto end of the optical lens 10 at close range to 0.005, the magnification Reds of the super-telephoto end of the optical lens 10 at close range is larger, which facilitates the optical lens 10 in photographing close-range subjects.

[0663] Among them, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state satisfies: Redss = 0.37. It can be understood that by restricting the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state to be equal to 0.37, the magnification Redss of the ultra-telephoto end of the optical lens 10 in the macro state is relatively appropriate, and the optical lens 10 can achieve shooting with a relatively large magnification for a relatively distant shooting object.

[0664] Among them, the refractive index Nd of the material of each lens of the optical lens 10 and the Abbe number Vd of each lens of the optical lens 10 satisfy:

[0665] 1.50 < Nd < 1.80, 20.35 < Vd < 81.56. It can be understood that by restricting the refractive index Nd of the material of each lens of the optical lens 10 to be within the range of 1.50 to 1.80, and restricting the Abbe number Vd of each lens of the optical lens 10 to be within the range of 20.35 to 81.56, the refractive index of each lens of the optical lens 10 is relatively small and the Abbe number is relatively large, and the light transmittance of the lenses of each lens of the optical lens 10 is relatively high. In this way, the light penetration ability of the lenses of each lens of the optical lens 10 is relatively strong, the optical quality of each lens of the optical lens 10 is relatively high, and the images taken by the optical lens 10 are clearer.

[0666] [[ID=�]]Among them, the focal length f2 of the second lens group G2 and the focal length fs of the ultra-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.38. It can be understood that by restricting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the ultra-telephoto end of the optical lens 10 to be equal to -0.38, the assembly tolerance between the first lens group G1 to the fourth lens group G4 is increased, and the loss of the resolution of the optical lens 10 is reduced.

[0667] Among them, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 satisfy: f1 / f2 = -2.80. It can be understood that by restricting the ratio of the focal length f1 of the first lens group G1 to the focal length f2 of the second lens group G2 to be equal to -2.80, the distribution of the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 is relatively reasonable. Under this distribution of the optical power, by reasonably setting the refractive index, Abbe number, shape, thickness, and air gap of the lenses in each lens group, a good balance among aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom magnification can be realized.

[0668] The distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction, the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction, and the focal length fs of the optical lens 10 at the super-telephoto end satisfy: |(ΔG3+ΔG4) / fs|=0.342. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to 0.342, the distance ΔG3 of the optical axis movement of the third lens group G3 along the second direction and the distance ΔG4 of the optical axis movement of the fourth lens group G4 along the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, thereby facilitating a compact design of the optical lens 10.

[0669] Figure 32A FIG1 is a first simulation effect diagram of the telephoto end of the camera module 300 according to the fifth embodiment.

[0670] like Figure 32A As shown, when the camera module 300 is at the telephoto end, the normalized coordinates of the camera module 300 are all small, the along-axis chromatic aberration (spherical aberration, chromatic aberration, etc.) of the camera module 300 is better corrected, and the imaging quality of the camera module 300 is higher.

[0674] like Figure 33A As shown, when the camera module 300 is at the telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0675] Figure 33B FIG2 is a second simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the fifth embodiment.

[0676] like Figure 33B As shown, when the camera module 300 is at the super telephoto end, the field curvature in both directions is small, the camera module 300 has a good depth of focus, and the imaging quality of the camera module 300 is high.

[0677] Figure 34A FIG3 is a third simulation effect diagram of the telephoto end of the camera module 300 according to the fifth embodiment.
