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 have higher and higher requirements for the camera performance of portable electronic devices' camera modules. Existing camera modules generally use multiple fixed-focus lenses, combined with digital zoom to achieve "jump zoom". However, jump zoom cannot meet users' shooting needs. In addition, the lens position in the existing fixed-focus lenses using digital zoom is fixed, and the existing fixed-focus lenses cannot achieve optical image stabilization. Therefore, existing camera modules cannot achieve continuous zoom and optical image stabilization at the same time. 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 is used to change the propagation direction of the optical axis from the first direction to the second direction, and the first direction is different from the second direction; during the anti-shake process of the optical lens, the first lens group rotates around the first direction, or around the second direction, or around the third direction, or around the first direction and the second direction, or around the second direction and the third direction, or around the first direction and the third direction, or around 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 the zooming 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 can move along the 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 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 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 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 can be understood that the first lens group has positive focal length, and the first lens group can shrink the light; the second lens group has negative focal length, and the second lens group can diverge the light. After the second lens group diverges the light, the field of view becomes smaller. The first lens group and the second lens group are used together to form a positive and negative lens matching structure, which can better solve aberration problems such as chromatic aberration. On the basis of achieving optical image stabilization and continuous zoom at the same time, the optical lens has a higher degree of freedom and better imaging quality.

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

[0008] In a 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 understandable that, since the third lens group and the fourth lens group can move along the optical axis of 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 not likely 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 thus facilitating the miniaturization of the optical lens.

[0010] In a possible implementation, during the process of the optical lens zooming 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 at the super telephoto end, the optical lens can achieve continuous zooming, and the shooting performance of the macro state at the super telephoto end of the optical lens is better.

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

[0013] It is understandable 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 optical power, and the fourth lens group has negative optical power.

[0015] It is understandable that the third lens group and the fourth lens group can cooperate to achieve the focus and zoom of the optical lens and the camera module, thereby improving the imaging quality of the optical lens and the camera module. The third lens group and the fourth lens group are used in conjunction to better solve aberration problems such as chromatic aberration, and the optical lens has a higher degree of freedom and better imaging quality.

[0016] It is understandable that, on the basis that the optical lens can simultaneously realize optical image stabilization and continuous zoom, the optical power configuration of the third lens group and the fourth lens group 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 system, axial thickness and curvature radius, etc., can be achieved, so that the optical lens can meet the requirements of high zoom ratio and continuous zoom while obtaining high imaging performance.

[0017] In a possible implementation, the optical lens satisfies: 0.2<|ΔG4 / ΔG3|<5, wherein 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 movement strokes of the third lens group and the fourth lens group during continuous zooming are close, and the movement strokes of the driving mechanism driving the third lens group and the fourth lens group to move are 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 a possible implementation, the optical lens satisfies: |(ΔG3+ΔG4) / fs|<5, where fs is the focal length of the super-telephoto end of the optical lens.

[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 can be compared with the scheme of the focal length of the same optical lens; compared with the scheme of 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 same third lens group, the focal length of the optical lens of the present application can be larger. In this way, 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 focal length of the corresponding optical lens, is beneficial to realizing the miniaturization 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 image stabilization performance of the first lens group is improved, thereby improving the optical image stabilization 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. In this way, 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 image stabilization performance of the first lens group is improved, thereby improving the optical image stabilization 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, fte = (ft × 43.27) / IHt, IHs is the image height at the ultra-long focal length end of the optical lens, and IHt is 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. In this way, by restricting the zoom ratio fse / fte of the optical lens to be 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. In this way, 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. In this way, 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 at the long focal length end of the optical lens 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 beneficial 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 beneficial 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 distant shooting object.

[0039] In a possible implementation, the material of the lens element 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 element of the optical lens to be within the range of 1.4 to 2.1, the refractive index of each lens element of the optical lens is smaller and the Abbe number is larger, and the light transmittance of each lens element of the optical lens is higher. In this way, the light penetration ability of each lens element of the optical lens is stronger, the optical quality of each lens element 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 element 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 element of the optical lens to be within the range of 15 to 96, the refractive index of each lens element of the optical lens is smaller and the Abbe number is larger, and the light transmittance of each lens element of the optical lens is higher. In this way, the light penetration ability of each lens element of the optical lens is stronger, the optical quality of each lens element 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. In this way, 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. In this way, 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 conducive 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 conducive 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 conducive to the optical lens to achieve clear and accurate imaging.

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

[0052] It is understandable that when the material of the deflecting element is resin, the weight of the deflecting element is relatively light, which is beneficial to reducing the overall weight of the optical lens. In addition, resin has good processing performance, and the manufacturing cost of resin is lower than that of glass.

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

[0054] When the material of the deflection element is 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 understandable that when the lens material of the lens of the second lens group is resin, the weight of the lens of the second lens group is relatively small, which is beneficial to reducing the overall weight of the optical lens. In addition, the lens of the second lens group has good resistance to vibration and impact. When the lens material of the lens of the second lens group is glass, the lens of the second lens group has excellent optical transparency, refractive index and chemical stability, is not easy to be scratched or deformed, and is beneficial to the optical lens to achieve clear and accurate imaging.

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

[0058] It is understandable that when the lens material of the lens of the third lens group is resin, the weight of the lens of the third lens group is relatively small, which is beneficial to reducing the overall weight of the optical lens. In addition, the lens of the third lens group has good resistance to vibration and impact. Exemplarily, when the lens material of the lens of the third lens group is glass, the lens of the third lens group has excellent optical transparency, refractive index and chemical stability, is not easy to scratch or deform, and is beneficial to the optical lens to 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 understandable that when the lens material of the lens of the fourth lens group is resin, the weight of the lens of the fourth lens group is relatively small, which is beneficial to reducing the overall weight of the optical lens. In addition, the lens of the fourth lens group has good resistance to vibration and impact. Exemplarily, when the lens material of the lens of the fourth lens group is glass, the lens of the fourth lens group has excellent optical transparency, refractive index and chemical stability, is not easy to scratch or deform, and is beneficial to the optical lens to 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 understandable that when the aperture is located between the second lens group and the third lens group, or located inside the second lens group or inside the third lens group, the aperture can achieve a large aperture effect at both the telephoto end and the super telephoto end of the optical lens. In addition, when the aperture is located between the second lens group and the third lens group, it is convenient to correct the aperture aberration. In addition, the optical lens of this embodiment has a large number of lenses for correcting aberrations, which is conducive to obtaining better imaging quality.

[0063] In one possible implementation, the optical lens further includes a light conversion element, which is located on the image side of the fourth lens group. The light conversion 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 the first direction and the second direction.

[0064] It can be understood that the light-deflecting 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-angle prism, and the angle a of the minimum acute angle α inside the light-redirecting element satisfies: 17.5°≤a≤37.5°.

[0066] It is understandable that the optical path conversion element can bend the optical path, which can increase the optical length and improve the imaging quality of the optical lens. The optical path conversion element can also compress the optical size, so that the size of the optical lens in the second direction is reduced, which is conducive to the miniaturization of the optical lens. The range of the angle a of the minimum acute angle α of the optical path conversion element is more appropriate, so that the angle between the third direction and the second direction is more appropriate, which is conducive to reducing the size of the optical lens in the second direction and the size in the third direction, thereby facilitating the miniaturization of the optical lens.

[0067] In a second aspect, the present application provides a camera module, which includes an image sensor and the above-mentioned 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.

[0069] In a third aspect, the present application provides an electronic device, which includes an image processor and the above-mentioned camera module, wherein the image processor is communicatively connected to the camera module, and the image processor is used to obtain 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 ratios, 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 clearly and completely described 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 "installation", "connection" and "connection" 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 parts are connected to each other and the relative position relationship after the connection remains unchanged. In addition, 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", "outside", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are for better and clearer description and understanding of the embodiments of the present application, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot 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 the present 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 when 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 one 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 before and after are in an "or" relationship. "Multiple" refers to 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 to zoom 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 scene forms a clear image on the focal plane through a lens or optical component. From a practical point of view, it can be understood as the distance from the center of the lens to the imaging plane. For a fixed-focus lens, the position of its optical center is fixed.

[0148] The focal length of an optical lens (effect focus) is defined as the distance from the center of the optical lens to the focus.

[0149] Focal power is defined as the difference between the image-side beam convergence and the object-side beam convergence. It 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] The telephoto end (te l escop icend) is the longer focal length section of the lens. The lens has a smaller angle of view and is used to shoot distant scenes, especially close-ups.

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

[0154] Super telephoto end (supertelephoto end) is the longest focal length of the lens and 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 (focal length at super telephoto end, 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 (midd l eend) of the camera module is defined as the intermediate state between the telephoto end and the super telephoto end.

[0157] The focal length of the mid-segment of the camera module (foca ll engthat midd l eend, FM) is defined as the distance from the center of the mid-segment 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 light to the speed of light in a vacuum when electromagnetic waves (including visible light) propagate in the material. It is an indicator that describes the propagation speed and degree of bending of light by the material.

[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 set screen with holes. Its function can be divided into two aspects: limiting the light beam or limiting the size of the field of view (imaging range). The aperture that limits the light beam the most in an optical system is called an aperture aperture; the aperture that limits the field of view (size) the most is called a field aperture.

[0162] Aberration, the paraxial region of the 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 that actually passes through different apertures of the lens is difficult to intersect perfectly at one point, but has 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 or position chromatic aberration or axial aberration, is a beam of light parallel to the optical axis that converges at different positions before and after passing through the lens. This aberration is called position chromatic aberration or axial chromatic aberration. This is because the positions of the images of the light of each wavelength are different, so that the focal planes of the image side of the light of different colors cannot overlap when the final image is formed, and the complex light spreads out to form dispersion.

[0164] Distortion, also known as distortion, is the degree of distortion of the image formed by the optical system relative to the object itself. Distortion is due to the influence of aperture spherical aberration. The height of the intersection of the main light of 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 imaging position of the off-axis object point on the ideal plane, causing the shape of the image to be distorted, but does not affect the clarity of the image.

[0165] Astigmatism (astigmatism), because the object point is not on the optical axis of the optical system, the light beam it emits has an inclination angle with the optical axis. After the light beam is refracted by the lens, the convergence point of its meridional beamlet and sagittal beamlet is not at the same point. That is, the light beam cannot be focused on one point, and the image is not clear, so astigmatism occurs. Meridian beamlet and sagittal beamlet are the names of light beams in two perpendicular planes in a rotationally symmetric optical system.

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

[0168] Field curvature is used to indicate the difference between the clearest image point position of the non-central field of view after the light passes through the optical lens group and the clearest image point position of the central field of view on the optical axis. When the lens has field curvature, the intersection point of the entire light beam does not coincide with the ideal image point. Although a clear image point can be obtained at each specific point, the entire image plane is a curved surface.

[0169] Figure 1A It is a schematic diagram of the structure 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 illustrated electronic device 1000 is a partial cross-sectional schematic diagram of an embodiment of the electronic device 1000 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 subject to the present invention. Figure 1A and Figure 1B limited.

[0173] Exemplarily, the screen 100 can be fixed to the housing 200, and the screen 100 can be used to display images to meet the user's usage needs. The display layer can be a liquid crystal display screen, an organic light emitting diode display screen, etc. The screen 100 and the housing 200 can enclose the interior of the electronic device 1000. The interior of the electronic device 1000 can be used to place components of the electronic device 1000, such as a battery, a receiver or a microphone, etc. Among them, the screen 100 can be a flat screen or a curved screen.

[0174] Exemplarily, 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, and 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 ellipse or an 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 the exterior of the electronic device 1000 can enter the interior of the electronic device 1000 through the light-transmitting portion 201, and is dustproof and waterproof. The camera module 300 can collect light from the exterior of the electronic device 1000 through the light-transmitting portion 201 to achieve the shooting of pictures or videos.

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

[0177] Understandably, Figure 1A The installation position of the camera module 300 of the electronic device 1000 in the illustrated embodiment is merely illustrative, and the present application does not strictly limit the installation position of the camera module 300. In some other embodiments, the camera module 300 may also be installed at other positions of the electronic device 1000, for example, the camera module 300 may be installed at the upper middle or 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 disassembled relative to the terminal body, and the camera module 300 may also be arranged on the auxiliary component.

[0178] Exemplarily, the image processor 400 can be connected to the camera module 300 for communication, and 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 through electrical connection methods such as wiring, and data transmission can also be achieved through coupling and other methods. It is understandable that the camera module 300 and the image processor 400 can also be connected to each other for communication through other methods that can achieve data transmission.

[0179] The image processor 400 may include a plurality of processing modules, which may be operated to convert the original image signal captured by the 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 through the display screen. The image processor 400 may be an image processing chip or a digital signal processing chip, which is used to adjust the color of the image, perform noise reduction processing on the image, etc., to further improve the image quality.

[0180] In the embodiment of the present application, the working principle of the camera module 300 in the electronic device 1000 can be: the light reflected by the photographed scene enters the interior of the camera module 300, generates an optical image and projects it 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, so as to be converted into a digital image signal by the analog-to-digital converter 500 and sent to the image processor 400, the image processor 400 can be operated to convert the original image signal captured by the camera module 300 to form image information, transmit the processed information to the screen 100, and display the image or video through the screen 100. In other embodiments, the electronic device 1000 can also include a memory (not shown in the drawings), and the image processor 400 can process the image digital signal and transmit the image to the memory, so that the image can be searched from the memory at any time and displayed on the screen 100 when the image needs to be viewed later.

[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, and this application does not limit this.

[0182] It is understandable that the number of camera modules 300 may be one or at least two. When the number of camera modules 300 is one, the camera module 300 may be used for 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 may 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 schematic structural diagram of an operation interface of an electronic device 1000 in one implementation manner.

[0184] like Figure 1A and Figure 2AAs shown, when the user of the electronic device 1000 is taking a photo with the electronic device 1000, the camera module 300, the image processor 400 and the analog-to-digital converter 500 are in operation, and the light reflected by the photographed object is collected by the camera module 300, converted by the analog-to-digital converter 500, and converted by the image processor 400 to form image information, which is displayed on the screen 100. In other embodiments, the shooting operation interface of the electronic device 1000 can also be in other forms. Specifically, this application does not limit it.

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

[0186] Exemplarily, 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] Exemplarily, in the process of zooming the camera module 300 from the telephoto end to the super telephoto end, the zoom ratio of the camera module 300 changes continuously. For example, when the camera module 300 is in the middle state between the telephoto end and the super telephoto end, the zoom ratio of the camera module 300 can be any value from 3 times to 10 times. For example, the zoom ratio of the camera module 300 can be 3.2 times, 4 times, 4.3 times, 5.1 times, 5.5 times, 6 times, 6.3 times, 6.9 times, 7 times, 7.8 times, 8 times, 9 times or 9.89 times, etc. It can be understood that in the process of zooming the camera module 300 from the super telephoto end to the telephoto end, the zoom ratio of the camera module 300 also changes continuously, and the zoom ratio of the camera module 300 can be any value from 10 times to 3 times.

[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 zooming 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 ratio of the camera module 300 may also be other values, for example, the zoom ratio of the telephoto end of the camera module 300 is 6 times. When the camera module 300 is at the super telephoto end, the zoom ratio of the camera module 300 may also be other values, for example, the zoom ratio of the super telephoto end of the camera module 300 is 10 times. At the same time, when the camera module 300 is in the middle state between the telephoto end and the super telephoto end, the zoom ratio of the camera module 300 may be any value between 6 times and 10 times. This application does not make any specific limitation.

[0190] like Figure 1B As shown, 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 understandable 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 subject to Figure 1B As defined in the following figures. It is understood that the camera module 300 may also include fewer or more structures. For example, the camera module 300 may include fewer structures, and illustratively, 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 figures).

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

[0192] Exemplarily, the filter 30 may 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 is imaged on the image sensor 20 through filtering of the light by the filter 30. Exemplarily, the filter 30 may be an infrared filter 30. The filter 30 may eliminate unnecessary light of a wavelength band projected onto the image sensor 20, and prevent the image sensor 20 from generating false colors or ripples, so as to improve its effective resolution and color reproduction. The present application does not strictly limit the specific embodiments of the structural members 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. The present application does not strictly limit the specific embodiments of the structural member or structure for implementing light filtering.

[0194] The following Figure 1B The implementation scheme of the optical lens 10 in the camera module 300 shown is illustrated by way of 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, and 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 a Z-axis direction. The second direction may be an X-axis direction. For example, the Z-axis direction may be a thickness direction of the electronic device 1000. The X-axis direction may be a width direction of the electronic device 1000. In other embodiments, the first direction and the second direction are not specifically limited.

[0197] Understandably, Figure 1B The following related figures only schematically illustrate some components of the optical lens 10, and the actual shapes, sizes, positions and structures of these components are not subject to Figure 1B As defined in the following figures. It is understandable 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 figures).

[0198] Exemplarily, the first lens group G1 may include one or more lenses and a folding element 1a, at least one of the one or more lenses is located on the object side of the folding element 1a, and the folding element 1a may be used to change the propagation direction of the optical axis from a first direction to a second direction. During the zooming process of the optical lens 10, the first lens group G1 may be a fixed lens group.

[0199] Exemplarily, the deflection element 1a may be a prism, a reflector or other components with a reflective function. The incident surface and the exit surface of the deflection element 1a may be optical surfaces such as a plane, a spherical surface or an aspherical surface. This application does not make any specific limitations.

[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] Exemplarily, 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] Exemplarily, the third lens group G3 may include at least two lenses. During the zooming process of the optical lens 10, the third lens group G3 may move along the optical axis of the second direction. In this way, the optical lens 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 10, the third lens group G3 may also be a fixed lens group.

[0203] Exemplarily, the fourth lens group G4 may include at least two lenses. During the zooming process of the optical lens 10, the fourth lens group G4 may move along the optical axis of the second direction. In this way, the optical lens 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 10, the fourth lens group G4 may also be a fixed lens group.

[0204] It can be understood that, since 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 not likely 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 drawings), the driving mechanism 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, and the driving mechanism 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] Illustratively, the first lens group G1 may have positive power, the second lens group G2 may have negative power, the third lens group G3 may have positive power, and the fourth lens group G4 may have negative 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 together to form a positive and negative lens matching 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 a role in shrinking light; the second lens group G2 has negative optical focal length, and the second lens group G2 can play a role in diverging light, and the second lens group G2 reduces the field of view angle after diverging the light; the third lens group G3 and the fourth lens group G4 can cooperate to achieve the focus and zoom 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 surfaces, focal lengths, refractive indices, the total optical length of the optical lens 10, the axial thickness and the radius of curvature, etc., can be reasonably used to enable the optical lens 10 to achieve high imaging performance while meeting the requirements of high zoom ratio and continuous zoom.

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

[0211] In some embodiments, the folding element 1a may not have optical power. Exemplarily, when the folding 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 folding element 1a. In this case, the first lens group G1 is composed of one or more lenses and the folding element 1a.

[0212] In some embodiments, the folding element 1a may have optical power. It is understandable that the folding element 1a having optical power can reduce the number of lenses of the first lens group G1, can 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 folding element 1a has optical power, the first lens group G1 is composed of one or more lenses and the folding 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 folding element 1a.

[0213] Exemplarily, the first lens group G1 may have an anti-shake compensation function. Exemplarily, during the optical anti-shake process of the optical lens 10, the first lens group G1 may rotate around the first direction, or around the second direction, or around the third direction, or around the first direction and the second direction, or around the second direction and the third direction, or around the first direction and the third direction, or around the first direction, the second direction and the third direction, to achieve optical anti-shake 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] Exemplarily, the third direction may also 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 camera module 300 shown is a simplified schematic diagram of a partial structure 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 may be parallel to the first direction. The first rotation axis O1 may pass through the deflection element 1a, or may 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 The position limit in .

[0220] For example, the first rotation center P1 may be located at any position on the first rotation axis O1. The first rotation center P1 may be located inside the deflection element 1a and at the intersection of the first rotation axis O1 and the deflection element 1a, or may be located at any other position inside the deflection element 1a, or may be located 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 folding element 1a and at the intersection of the first rotation axis O1 and the folding element 1a, and the specific position of the first rotation center P1 is not affected. Figure 2B The position limit 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 may be parallel to the second direction, and the second rotation axis O2 may intersect with the first rotation axis O1. The second rotation axis O2 may pass through the deflection element 1a, or may 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 The position limit in .

[0224] For example, the second rotation center P2 can be 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 folding element 1a and at the intersection of the second rotation axis O2 and the folding element 1a, or at any other position inside the folding element 1a, or outside the folding element 1a. It is understandable 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 The position limit in .

[0225] It is understandable 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, illustratively, the first lens group G1 can also rotate around a third direction. The third direction can be any direction on the plane formed by the first direction and the second direction (i.e., the XZ plane), or a direction perpendicular to the plane formed by the first direction and the second direction. This application does not make any specific limitations.

[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, can intersect with the first rotation axis O1 and the second rotation axis O2 and be perpendicular, 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, intersecting and being 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 Figure 2B The position limit in .

[0229] For example, the third rotation center P3 may be located at any position on the third rotation axis O3, may be located inside the folding element 1a and at the intersection of the third rotation axis O3 and the folding element 1a, may be located at any other position inside the folding element 1a, or may be located outside the folding 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 Figure 2B limited.

[0230] It is understandable 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, exemplarily, when the third direction is a direction perpendicular to the plane formed by the first direction and the second direction, the distance between the intersection of the first direction and the second direction and the third direction is d, and d satisfies: 0<d≤10mm (millimeter), for example, d can be equal to 0.5mm, 1mm, 1.4mm, 2.8mm, 3.3mm, 4.8mm, 5mm, 6.67mm, 7mm, 8.88mm, 9.5mm or 10mm. It can be understood that when the first lens group G1 rotates around the third direction, the optical image stabilization effect of the optical lens 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 around the third direction, the optical image stabilization effect of the optical lens 10 is better.

[0233] In other implementations, the distance d between the intersection of the first direction and the second direction and the third direction may also meet other ranges. This application does not make any specific limitations.

[0234] Exemplarily, the anti-shake driving mechanism may also be connected to the first lens group G1, and the anti-shake driving mechanism may be used to drive the first lens group G1 to move, so as to achieve optical anti-shake of the optical lens 10. In other embodiments, the anti-shake driving mechanism of the first lens group G1, the driving mechanism of the third lens group G3, and the driving mechanism of the fourth lens group G4 may be integrated into one driving mechanism. The design of the anti-shake driving mechanism of the first lens group G1, the driving mechanism of the third lens group G3, and the driving mechanism of the fourth lens group G4 may be flexibly adjusted according to actual needs, and this application does not make specific limitations.

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

[0236] like FIG. 3A to FIG. 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 can be understood that the first sub-direction and the second sub-direction can be flexibly set according to actual needs, and the present application does not specifically limit them.

[0237] like FIG. 3A to FIG. 3C As shown, exemplarily, in the process of zooming 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, and the third lens group G3 and the fourth lens group G4 can move along the optical axis of the first sub-direction. At this time, the distance between the second lens group G2 and the third lens group G3 is reduced. When the optical lens 10 is at the super telephoto end, the optical lens 10 can focus on a distant subject (including a user using the optical lens 10).

[0238] like FIG. 3A to FIG. 3C As shown, illustratively, during the process of zooming 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, and the third lens group G3 and the fourth lens group G4 can move along the optical axis of 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 users using the optical lens 10).

[0239] It is understandable that, since 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 not likely 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. Figure 1B The illustrated aperture 5 is located between the second lens group G2 and the third lens group G3. The aperture 5 may also be located inside the second lens group G2 or inside the third lens group G3. The position of the aperture 5 may be flexibly adjusted according to actual needs.

[0242] It can be understood that when the aperture 5 is located between the second lens group G2 and the third lens group G3, or when the aperture 5 is located inside the second lens group G2 or inside the third lens group G3, the aperture 5 can achieve a large aperture effect at both the telephoto end and the super telephoto end of the optical lens 10. In addition, when the aperture 5 is located between the second lens group G2 and the third lens group G3, it is convenient to correct the aberration of the aperture 5. In addition, the optical lens 10 of this embodiment has a large number of lenses for correcting aberrations, which is conducive to obtaining better imaging quality.

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

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

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

[0246] like Figure 3C and Figure 4A As shown, exemplarily, in the process of zooming the camera module 300 from the super telephoto end to the close-up 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. At this time, the distance between the third lens group G3 and the second lens group G2 decreases, and 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 super telephoto end to the close-up state of the super telephoto end, the first lens group G1, the second lens group G2, and the third lens group G3 may all be fixed lens groups, and the fourth lens group G4 may 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 super telephoto end to the close-up state of the super telephoto end, the first lens group G1 and the second lens group G2 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit it.

[0248] like Figure 4A and Figure 4B As shown, exemplarily, in the process of zooming 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 of the second sub-direction. At this time, 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 may all be fixed lens groups, and the third lens group G3 may 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 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit this.

[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 a macro state at the telephoto end.

[0251] like Figure 3A and Figure 5 As shown, exemplarily, in the process of zooming 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, and the third lens group G3 can move along the direction of 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 is reduced, and the distance between the third lens group G3 and the fourth lens group G4 is increased.

[0252] In some embodiments, during the process of zooming 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 may all be fixed lens groups, and the fourth lens group G4 may 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 process of zooming 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 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit it.

[0253] The structure of the optical lens 10 is described in detail above in conjunction with the related drawings. The setting of the related optical parameters of the optical lens 10 will be described in detail below in conjunction with the drawings.

[0254] Exemplarily, the optical lens 10 can satisfy: 0.2<|ΔG4 / ΔG3|<5, wherein 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 of the distance ΔG4 of the fourth lens group G4 moving along the second direction to the distance ΔG3 of the third lens group G3 moving along the second direction |ΔG4 / ΔG3| may also satisfy other ranges. This application does not limit this in detail.

[0257] It can be understood that, in order to facilitate the description of the movement direction of the third lens group G3 and the fourth lens group G4, it is defined 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 actual needs.

[0258] Exemplarily, the optical lens 10 may satisfy: |(ΔG3 + ΔG4) / fs| < 5. For example, |(ΔG3 + ΔG4) / fs| may 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 focal length of the same optical lens 10, the distances ΔG3 of the third lens group G3 moving along the optical axis in the second direction and ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction can be both smaller; compared with the solution of the distances ΔG3 of the third lens group G3 moving along the optical axis in the second direction and ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction, the focal length of the optical lens 10 in this application can be larger. Thus, by restricting |(ΔG3 + ΔG4) / fs| within a range less than 5, reducing the distances ΔG3 of the third lens group G3 moving along the optical axis in the second direction and ΔG4 of the fourth lens group G4 moving along the optical axis in the second direction, or increasing the focal length of the corresponding optical lens 10, is beneficial to achieving the miniaturized setting of the optical lens 10.

[0259] In other embodiments, |(ΔG3 + ΔG4) / fs| may also satisfy other ranges. Specifically, this application does not make a limitation.

[0260] Exemplarily, the optical lens 10 may 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 may 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 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 may also satisfy other ranges. Specifically, this application does not make a limitation.

[0262] Exemplarily, the optical lens 10 may 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 any limitations.

[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 image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization 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 any limitations.

[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 can be improved.

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

[0269] Exemplarily, the optical lens 10 can 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)| can 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 accurately controlled, and the focusing effect of the optical lens 10 can be improved.

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

[0272] Exemplarily, the optical lens 10 can satisfy: -10 < f12 / f3 < 0, where f3 is the focal length of the third lens group G3. For example, f12 / f3 can 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 a range of -10 to 0, 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.

[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 can also satisfy other ranges. Specifically, the present 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 closer to the first lens group G1. The optical lens 10 can satisfy: Redt > 0.15, where Redt is the magnification 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 Redt of the telephoto end of the optical lens 10 in the macro state within a range greater than 0.15, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is relatively large, which is beneficial to realizing the shooting of the shooting object in the macro state by the optical lens 10.

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

[0276] Exemplarily, when the optical lens 10 is at the ultra-telephoto end, the third lens group G3 can move towards the direction closer to the first lens group G1. The optical lens 10 can satisfy: Reds > 0.025, where Reds is the magnification 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 Reds of the ultra-telephoto end of the optical lens 10 in the near state within a range greater than 0.025, the magnification Reds of the ultra-telephoto end of the optical lens 10 in the near state is relatively large, which is beneficial to realizing the shooting of the shooting object in the near state by the optical lens 10.

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

[0278] Exemplarily, when the optical lens 10 is at the ultra-telephoto end, the fourth lens group G4 can move towards the direction 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 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 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 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 relatively large magnification for a relatively distant 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. This application does not make any specific limitations.

[0280] Exemplarily, the lens material of the first lens group G1 can be resin. It can be understood that the weight of the lens of the first lens group G1 is relatively small, which is conducive to reducing the overall weight of the optical lens 10. In addition, the lens of the first lens group G1 has good resistance to vibration and impact.

[0281] Exemplarily, the lens material of the first lens group G1 can also be glass. It is understandable that the lens of the first lens group G1 has excellent optical transparency, refractive index and chemical stability, is not easy to be scratched or deformed, and is conducive to the optical lens 10 to achieve clear and accurate imaging.

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

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

[0284] For example, when the material of the deflection element 1a is resin, the deflection element 1a is light in weight, which is helpful to reduce the overall weight of the optical lens 10. In addition, resin has good processing performance, and the manufacturing cost of resin is lower than that of glass.

[0285] Exemplarily, 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] Exemplarily, 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 further 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 deflection element 1a may also be made of other materials, which is not specifically limited in this application.

[0290] Exemplarily, the lens material of the second lens group G2 can be resin. It can be understood that the weight of the lens of the second lens group G2 is relatively small, which is conducive to reducing the overall weight of the optical lens 10. In addition, the lens of the second lens group G2 has good resistance to vibration and impact.

[0291] Exemplarily, the lens material of the second lens group G2 can also be glass. It is understandable that the lens of the second lens group G2 has excellent optical transparency, refractive index and chemical stability, is not easy to be scratched or deformed, and is conducive to the optical lens 10 to achieve clear and accurate imaging.

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

[0293] Exemplarily, the lens material of the lenses of the third lens group G3 may be resin. It is understandable that the weight of the lenses of the third lens group G3 is relatively small, which is beneficial to reducing the overall weight of the optical lens 10. In addition, the lenses of the third lens group G3 have good resistance to vibration and impact.

[0294] Exemplarily, the lens material of the third lens group G3 may also be glass. It is understandable that the lens of the third lens group G3 has excellent optical transparency, refractive index and chemical stability, is not easy to be scratched or deformed, and is conducive to the optical lens 10 to achieve clear and accurate imaging.

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

[0296] Exemplarily, the lens material of the fourth lens group G4 can be resin. It can be understood that the weight of the lens of the fourth lens group G4 is relatively small, which is conducive to reducing the overall weight of the optical lens 10. In addition, the lens of the fourth lens group G4 has good resistance 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 beneficial for the optical lens 10 to achieve clear and accurate imaging.

[0298] In other embodiments, the lens lenses of the fourth lens group G4 can also use other materials. Specifically, the present 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 lens material of each lens of the optical lens 10, and Vd is the Abbe number of the lens material of each 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 lens material of each lens of the optical lens 10 within the range of 1.4 to 2.1 and restricting the Abbe number Vd of the lens material of each lens of the optical lens 10 within the range of 15 to 96, the refractive index of each lens of the optical lens 10 is smaller, the Abbe number is larger, and the light transmittance of each lens of the optical lens 10 is higher. In this way, the light penetration ability 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 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, the present 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 length end of the optical lens 10 within the range of -5 to 0, 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.

[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 length end of the optical lens 10 can also satisfy other ranges. Specifically, the present application does not make any limitations.

[0303] Exemplarily, the optical lens 10 can satisfy: -8 < f1 / f2 < 0. For example, f1 / f2 can 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 focal lengths f1 of the first lens group G1 and f2 of the second lens group G2 are reasonably allocated. With 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 can also satisfy other ranges. Specifically, the present 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 with reference to the relevant drawings.

[0306] As FIG. 3A to FIG. 3C shown, exemplarily, the camera module 300 includes a first lens group G1, a second lens group G2, a diaphragm 5 (not shown in the attached Figure 3A to the attached 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 can all have positive optical power. The second lens L2, the fourth lens L4, the seventh lens L7, and the ninth lens L9 can 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 infinitely far shooting object, 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 surface 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 spacing between the second lens group G2 and the third lens group G3 is reduced, and the spacing 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] Exemplarily, 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. Among them, 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 can satisfy: 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 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 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 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 power.

[0312] For example, the folding element 1a can be a prism, which can change the propagation direction of the optical axis from the first direction to the second direction, and fold the light emitted by the first lens L1 and then incident on the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a unique two-dimensional plane, namely the XZ plane.

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

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

[0316]

[0317]

[0319] 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 folding element 1a.

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 S24 refers to the distance between the image side surface and the imaging surface of the filter 30.

[0320] In Table 1a, the thickness values ​​with positive and negative represent that the thickness has a direction. Exemplarily, the direction of the light without being reflected by the refracting element 1a is the positive direction, and the thickness value is a positive value; the direction of the light after being reflected by the refracting element 1a is the negative direction, and the thickness value is a negative value. It is understood that when the subsequent tables appear again, if the meanings they represent are the same, they will not be repeated.

[0321] In other embodiments, the direction of the light after being reflected by the refracting element 1a may be a positive direction, and the thickness may be a positive value; the direction of the light without being reflected by the refracting element 1a may be a negative direction, and the thickness may be a negative value. This application does not limit this.

[0322] Among them, the materials of 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, and the materials of the second lens L2 and the folding element 1a are all made of glass. It can be understood that by using the resin lens and the glass lens in combination, the camera module 300 can have the characteristics of lighter weight, better durability and excellent optical performance.

[0323] In addition, the aspheric coefficients of each lens of the camera module 300 of 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 of 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. The polynomial coefficients that do not exist in the table (such as A1, A2, A3, etc.) are all 0. It can be 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 understandable that among the 18 aspherical surfaces of the camera module 300 shown in Table 1a and Table 1b, the surface types z of all even-order and odd-order aspherical surfaces can be defined by, but not limited to, the following aspherical surface formula:

[0328]

[0329] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex spherical curvature of the aspheric surface, K is the quadratic surface constant, and A i 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 surface and image side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 of 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 the following Table 1c.

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

[0332] fL fL fL fL fL fL fL f8 fL 58.05 -23.13 11.41 -16.42 23.32 25.96 -50.09 22.80 -9.65

[0333] Among them, fL1 can represent the focal length of the first lens L1; fL2 can represent the focal length of the second lens L2; ​​fL3 can represent the focal length of the third lens L3; fL4 can represent the focal length of the fourth lens L4; fL5 can represent the focal length of the fifth lens L5; fL6 can represent the focal length of the sixth lens L6; fL7 can represent the focal length of the seventh lens L7; fL8 can represent the focal length of the eighth lens L8; fL9 can represent the focal length of the ninth lens L9. It can be understood that in this application, when the subsequent tables appear again, the symbols representing the same meaning 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 power; the focal length fL6 of the sixth lens L6 satisfies: fL6=25.96 mm, and the sixth lens L6 may have positive power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-50.09 mm, and the seventh lens L7 may have negative power; the focal length fL8 of the eighth lens L8 satisfies: fL8=22.80 mm, and the eighth lens L8 may have positive power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-9.65 mm, and the ninth lens L9 may have negative 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 the following Table 1d.

[0337] Table 1d Partial parameters of the camera module 300 of the first embodiment

[0338] f1 f2 f3 f4 f12 f123t f123s 58.05 -23.13 10.74 -11.08 -62.91 15.38 16.38 ft fs fm fse fte ΔG3 ΔG4 23.50 31.20 27.43 215.40 81.12 2.97 4.30 Redt Reds Redss Ih IH 0.64 0.03 0.23 12.53 6.27

[0339] Among them, f4 may represent the focal length of the fourth lens group G4, and fm may represent the focal length of the camera module 300 in the middle section. It is understood that in this application, when the subsequent tables appear again, the symbols representing the same meaning 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 together to form a positive and negative lens matching 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] Among them, the focal length ft of the telephoto end of the optical lens 10 and the focal length fs of the super telephoto end of the optical lens 10 satisfy: ft / fs=0.75. It can be understood that by limiting the ratio of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the super telephoto end of the optical lens 10 to be equal to 0.75, the range of values ​​of the zoom ratio and zoom magnification of the optical lens 10 is larger, and the optical lens 10 has a larger field of view coverage.

[0343] The optical lens 10 satisfies: fse / fte=2.64. It can be understood that by limiting fse / fte to 2.64, the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can simultaneously achieve a shorter focal length and a longer focal length, which is conducive to achieving the super telephoto end and telephoto end shooting of the optical lens 10.

[0344] Among them, the distance ΔG3 of the third lens group G3 moving along the second direction of the optical axis and the distance ΔG4 of the fourth lens group G4 moving along the second direction of the optical axis satisfy: ΔG4 / ΔG3=1.45. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the third lens group G3 moving along the second direction of the optical axis and the distance ΔG4 of the fourth lens group G4 moving along the second direction of the optical axis to be equal to 1.45, the respective movement strokes of the third lens group G3 and the fourth lens group G4 in the continuous zooming process are close, and the travel when the driving mechanism drives the third lens group G3 and the fourth lens group G4 to move is small, which is conducive to realizing the miniaturization setting of the optical lens 10, and at the same time, the structure of the driving mechanism is simpler.

[0345] The focal length f1 of the first lens group G1 and the focal length ft of the telephoto end of the optical lens 10 satisfy: 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 of the telephoto end of the optical lens 10 to be equal to 2.47, 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.

[0346] Among them, 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 accurately controlled, thereby improving the focus 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 accurately controlled, thereby improving the focus 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 be equal to -5.86, 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.

[0352] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt=0.635. It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to be equal to 0.635, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, which is conducive to the optical lens 10 shooting the shooting object in the macro state.

[0353] The magnification Reds of the super telephoto end of the optical lens 10 in the close-up state satisfies: Reds = 0.03. It can be understood that by limiting the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state to 0.03, the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state is relatively large, which is conducive to the optical lens 10 shooting the shooting object at a close distance.

[0354] Among them, the magnification Redss of the ultra-long focal 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-long focal end of the optical lens 10 in the macro state to be equal to 0.23, the magnification Redss of the ultra-long focal 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 in the range of 1.51 to 1.77, and restricting the Abbe number Vd of each lens of the optical lens 10 to be in 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 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-long focal 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-long focal end of the optical lens 10 to be equal to -0.74, 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.

[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 / f2 = -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 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] Among them, 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 super telephoto end of the optical lens 10 satisfy: |(ΔG3+ΔG4) / fs|=0.23. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to be equal to 0.23, reducing 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, or increasing the focal length of the corresponding optical lens 10, it is beneficial to realize the miniaturization setting of the optical lens 10.

[0360] Fig. 6A FIG. 1 is a simulation effect diagram of the telephoto end of the camera module 300 according to the first embodiment.

[0361] Understandably, Fig. 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 the present 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 Fig. 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 FIG. 1 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] Fig. 7A FIG2 is a second simulation effect diagram of the telephoto end of the camera module 300 according to the first embodiment.

[0366] Understandably, Fig. 7AThe curve may represent the astigmatism field curvature curve of the camera module 300. The astigmatism field curvature curve may represent the meridional image curvature and the sagittal image curvature, and is used to illustrate the deviation of the convergence point of the fine light beams in different fields of view from the ideal imaging surface, wherein the solid line is the meridional direction light beam, the dotted line is the sagittal direction light beam, the abscissa thereof is the deviation value along the optical axis O, and the ordinate is the corresponding field of view. It is to be understood that in the present application, when the abscissa, ordinate and annotations in the figure that represent the same meaning appear again in the subsequent coordinate system representing the astigmatism field curvature curve of the camera module 300, they will not be described in detail.

[0367] like Fig. 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 of 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] Fig. 8A FIG3 is a simulation effect diagram of the telephoto end of the camera module 300 of the first embodiment.

[0371] Understandably, Fig. 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, wherein the horizontal axis is the optical distortion ratio and the vertical axis is the image height IH (mm). It is understood that in this application, when the horizontal axis, vertical axis and annotations in the figure that represent the same meaning appear again in the subsequent coordinate system representing the distortion curve of the camera module 300, they will not be repeated.

[0372] like Fig. 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 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 of 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 optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

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

[0376] like 9A to 9C As shown, the camera module 300 includes a first lens group G1, a second lens group G2, and a stop 5 (attached) arranged in sequence from the object side to the image side. Fig. 9A To Attachment Fig. 9C ), a third lens group G3, a fourth lens group G4, a filter 30 and an image sensor 20.

[0377] 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.

[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 9A to 9CAs shown, 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 infinitely far shooting object, 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 surface in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can move along the optical axis of the first sub-direction of the second direction at the same time, so that the spacing between the second lens group G2 and the third lens group G3 is reduced, and the spacing 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] Exemplarily, 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. Among them, 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 can satisfy: 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 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 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 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 power.

[0382] For example, the folding element 1a can be a prism, which can change the propagation direction of the optical axis from the first direction to the second direction, and fold the light emitted by the first lens L1 and then enter the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a unique two-dimensional plane, namely the XZ plane.

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

Fig. 10B yes Fig. 10A The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. It can be understood that Fig. 10A and Fig. 10B The camera module 300 is respectively in a close-range state at the super-telephoto end and a macro state at the super-telephoto end.

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

[0398] Among them, the materials of the lenses of 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, and the materials of the second lens L2, the folding element 1a, the sixth lens L6 and the filter 30 are all made of glass. It can be understood that by using the resin lens and the glass lens in combination, the camera module 300 can have the characteristics of lighter weight, better durability and excellent optical performance.

[0399] In addition, the aspheric coefficients of each lens of the camera module 300 of the second embodiment of the present application are shown in Table 2b below.

[0401]

[0402]

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

[0404]

[0405] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex spherical curvature of the aspheric surface, K is the quadratic surface constant, and A i 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 surface and image side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 of the second embodiment of the present application can be obtained.

[0406] According to 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] fL fL fL fL fL fL fL f8 fL 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=26.78mm, the fifth lens L5 may have positive power; the focal length fL6 of the sixth lens L6 satisfies: fL6=18.49mm, the sixth lens L6 may have positive power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-19.63mm, the seventh lens L7 may have negative power; the focal length fL8 of the eighth lens L8 satisfies: fL8=19.05mm, the eighth lens L8 may have positive power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-12.36mm, the ninth lens L9 may have negative 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] According to 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 the following Table 2d.

[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 IH 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 together to form a positive and negative lens matching 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] Among them, the focal length ft of the telephoto end of the optical lens 10 and the focal length fs of the super telephoto end of the optical lens 10 satisfy: ft / fs=0.76. It can be understood that by limiting the ratio of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the super telephoto end of the optical lens 10 to be equal to 0.76, the range of values ​​of the zoom ratio and zoom magnification of the optical lens 10 is larger, and the optical lens 10 has a larger field of view coverage.

[0418] The optical lens 10 satisfies: fse / fte=2.64. It can be understood that by limiting fse / fte to 2.64, the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can simultaneously achieve a shorter focal length and a longer focal length, which is conducive to achieving the super telephoto end and telephoto end shooting of the optical lens 10.

[0419] Among them, 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 and 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 respective movement strokes of the third lens group G3 and the fourth lens group G4 during the continuous zooming process are close, and the travel when the driving mechanism drives the third lens group G3 and the fourth lens group G4 to move is small, which is conducive to realizing the miniaturization setting of the optical lens 10, and at the same time, the structure of the driving mechanism is simpler.

[0420] The focal length f1 of the first lens group G1 and the focal length ft of the telephoto end of the optical lens 10 satisfy: 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 of the telephoto end of the optical lens 10 to be equal to 2.47, 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.

[0421] Among them, 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 accurately controlled and the focus effect of the optical lens 10 can be improved.

[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 accurately controlled, thereby improving the focus 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 be equal to -5.41, 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.

[0427] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt=0.39. It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to be equal to 0.39, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, which is conducive to the optical lens 10 shooting the shooting object in the macro state.

[0428] The magnification Reds of the super telephoto end of the optical lens 10 in the close-up state satisfies: Reds = 0.03. It can be understood that by limiting the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state to 0.03, the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state is relatively large, which is conducive to the optical lens 10 shooting the shooting object at a close distance.

[0429] 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.

[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 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 20.4 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 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-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.71. 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 -0.71, 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.

[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 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 -2.59, 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.

[0434] Among them, 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 super telephoto end of the optical lens 10 satisfy: |(ΔG3+ΔG4) / fs|=0.23. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to be equal to 0.23, reducing 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, or increasing the focal length of the corresponding optical lens 10, it is beneficial to realize the miniaturization setting of the optical lens 10.

[0435] Fig. 12A FIG. 1 is a simulation effect diagram of the telephoto end of the camera module 300 according to the second embodiment.

[0436] like Fig. 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] Fig. 12B FIG. 1 is a simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the second embodiment.

[0438] like Fig. 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] Fig.13A FIG2 is a second simulation effect diagram of the telephoto end of the camera module 300 according to the second embodiment.

[0440] like Fig.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] Fig. 13B FIG2 is a second simulation effect diagram of the ultra-telephoto end of the camera module 300 according to the second embodiment.

[0442] like Fig. 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] Fig.14A FIG3 is a simulation effect diagram of the telephoto end of the camera module 300 according to the second embodiment.

[0444] like Fig.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 optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

[0445] Fig. 14B FIG3 is a simulation effect diagram of the ultra-telephoto end of the camera module 300 of the second embodiment.

[0446] like Fig. 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 optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

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

[0448] like FIG. 15A to FIG. 15C As shown, the camera module 300 includes a first lens group G1, a second lens group G2, and a stop 5 (attached) arranged in sequence from the object side to the image side. Fig.15A To Attachment Fig. 15C ), a third lens group G3, a fourth lens group G4, a light switching element 6, a filter 30 and an image sensor 20.

[0449] 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.

[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 FIG. 15A to FIG. 15C As shown, illustratively, the light conversion element 6 can be located on the image side of the fourth lens group G4, and the light conversion element 6 can change the propagation direction of the optical axis from the second direction to the fourth direction. The fourth direction is different from the first direction and the second direction. At this time, the filter 30 and the image sensor 20 can be arranged facing the exit surface of the light conversion element 6.

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

[0453] Exemplarily, the optical path conversion element 6 can bend the optical axis in the second direction so that the optical path is turned to a certain angle. It is understandable that the optical path conversion element 6 can bend the optical path, which can increase the optical length and improve the imaging quality of the optical lens 10. The optical path conversion element 6 can also compress the optical size so that the size of the optical lens 10 in the second direction is reduced, which is conducive to realizing the miniaturization of the optical lens 10 and the camera module 300.

[0454] Exemplarily, when the light-converting element 6 is an oblique prism, the light-converting element 6 may satisfy: 17.5°≤a≤37.5°, wherein a is the angle a of the minimum acute angle α inside the light-converting element 6, for example, a may be equal to 17.5°, 18.36°, 22°, 24°, 27.5°, 29.5°, 33°, 36.1° or 37.5°, etc. It can be understood that the range of the angle a of the minimum acute angle α of the light-converting element 6 is more appropriate, so that the angle between the third direction and the second direction is more appropriate, which is conducive to reducing the size of the optical lens 10 in the second direction and the size in the third direction, thereby facilitating the miniaturization 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 Fig.15A To Attachment Fig. 15C The rectangle in the figure only schematically shows the relative position of the light deflection element 6 in the camera module 300. The actual shape and direction of the optical axis of the light deflection element 6 are not affected by the attached Fig.15A To Attachment Fig. 15C limit.

[0457] like FIG. 15A to FIG. 15CAs shown, 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 infinitely far shooting object, 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 surface in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can move along the optical axis of the first sub-direction of the second direction at the same time, so that the spacing between the second lens group G2 and the third lens group G3 is reduced, and the spacing 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] Exemplarily, 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. Among them, 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 can satisfy: 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 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 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 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 power.

[0460] For example, the folding element 1a can be a prism, which can change the propagation direction of the optical axis from the first direction to the second direction, and fold the light emitted by the first lens L1 and then incident on the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a unique two-dimensional plane, namely the XZ plane.

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

Fig. 16B yes Fig.16A The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. It can be understood that Fig.16A and Fig. 16B The camera module 300 is respectively in a close-range state at the super-telephoto end and a macro state at the super-telephoto end.

[0463] like Fig. 15C and Fig.16A As shown, exemplarily, during the zooming process of the camera module 300 from the super telephoto end to the close-up state of 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 of 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 super telephoto end to the close-up state of the super telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 may all be fixed lens groups, and the third lens group G3 may 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 super telephoto end to the close-up state of the super telephoto end, the first lens group G1 and the second lens group G2 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit it.

[0465] like Fig.16A and Fig. 16B As shown, exemplarily, in the process of zooming 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 of the second sub-direction. At this time, 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 may all be fixed lens groups, and the third lens group G3 may 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 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit this.

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

[0468] Fig.17 yes Fig.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 Fig.17 The camera module 300 is in a macro state at the telephoto end.

[0469] like Fig.15A and Fig.17 As shown, exemplarily, in the process of zooming 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, and 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, and the distance between the third lens group G3 and the fourth lens group G4 increases.

[0470] In some embodiments, during the process of zooming 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 may all be fixed lens groups, and the fourth lens group G4 may 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 process of zooming 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 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit it.

[0479] Among them, the materials of 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, and the materials of the second lens L2, the folding element 1a, the light transfer element 6 and the filter 30 are all made of glass. It can be understood that by using the resin lens and the glass lens in combination, the camera module 300 can have the characteristics of light weight, good durability and excellent optical performance.

[0480] In addition, the aspheric coefficients of each lens of the camera module 300 of 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 of the third embodiment

[0482]

[0483]

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

[0485]

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

[0487] According to 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] fL fL fL fL fL fL fL f8 fL 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, the fifth lens L5 may have positive power; the focal length fL6 of the sixth lens L6 satisfies: fL6=37.63mm, the sixth lens L6 may have positive power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-24.83mm, the seventh lens L7 may have negative power; the focal length fL8 of the eighth lens L8 satisfies: fL8=34.86mm, the eighth lens L8 may have positive power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-17.58mm, the ninth lens L9 may have negative power.

[0491] 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. According to 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 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 together to form a positive and negative lens matching 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] Among them, the focal length ft of the telephoto end of the optical lens 10 and the focal length fs of the super telephoto end of the optical lens 10 satisfy: ft / fs=0.74. It can be understood that by limiting the ratio of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the super telephoto end of the optical lens 10 to be equal to 0.74, the value range of the zoom ratio and zoom magnification of the optical lens 10 is larger, and the optical lens 10 has a larger field of view coverage.

[0499] The optical lens 10 satisfies: fse / fte=2.71. It can be understood that by limiting fse / fte to 2.71, the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can simultaneously achieve a shorter focal length and a longer focal length, which is conducive to achieving the super telephoto end and telephoto end shooting of the optical lens 10.

[0500] Among them, 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 satisfy: ΔG4 / ΔG3=1.08. It can be understood that by limiting the absolute value of the ratio of 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 to be equal to 1.08, the respective moving strokes of the third lens group G3 and the fourth lens group G4 in the continuous zooming process are close, and the driving mechanism drives the third lens group G3 and the fourth lens group G4 to move with a smaller stroke, which is conducive to realizing the miniaturization of the optical lens 10, and at the same time, the structure of the driving mechanism is simpler.

[0501] The focal length f1 of the first lens group G1 and the focal length ft of the telephoto end of the optical lens 10 satisfy: f1 / ft=1.51. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 and the focal length ft of the telephoto end of the optical lens 10 to be equal 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] Among them, 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 accurately controlled, thereby improving the focus 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 accurately controlled, thereby improving the focus 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 be equal to -3.38, 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.

[0508] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt=0.31. It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to be equal to 0.31, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, which is conducive to the optical lens 10 shooting the object in the macro state.

[0509] The magnification Reds of the super telephoto end of the optical lens 10 in the close-up state satisfies: Reds = 0.03. It can be understood that by limiting the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state to 0.03, the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state is relatively large, which is conducive to the optical lens 10 shooting the shooting object at a close distance.

[0510] Among them, the magnification Redss of the ultra-long focal length 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-long focal length end of the optical lens 10 in the macro state to be equal to 0.18, 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.

[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 each lens of the optical lens 10 is higher. In this way, the light penetration ability 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-long focal length 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-long focal length end of the optical lens 10 to be equal to -0.34, 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.

[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 distributed. 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] Among them, 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 super telephoto end of the optical lens 10 satisfy: |(ΔG3+ΔG4) / fs|=0.21. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to be equal to 0.21, reducing 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, or increasing the focal length of the corresponding optical lens 10, it is beneficial to realize the miniaturization setting of the optical lens 10.

[0525] like Fig. 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 optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

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

[0527] like Fig. 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 optical distortion of the image is small, and the imaging quality of the camera module 300 is high.

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

[0529] like Fig.21 As shown, illustratively, the light-redirecting 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-redirecting element 6 .

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

[0531] like Fig. 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: Fig.23A yes Figure 1B The fourth simplified schematic diagram of a partial structure of the camera module 300 in one embodiment is shown. Fig. 23B yes Fig.23A The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. Fig.23C yes Fig. 23B The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. It can be understood that FIG. 23A to FIG. 23C The camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0533] like FIG. 23A to FIG. 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 folding 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 folding 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, and 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 FIG. 23A to FIG. 23C As shown, 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 infinitely far shooting object, 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 surface in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can move along the optical axis of the first sub-direction of the second direction at the same time, so that the spacing between the second lens group G2 and the third lens group G3 is reduced, and the spacing 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] Exemplarily, 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. Among them, 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 can satisfy: 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 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 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 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 power.

[0539] For example, the folding element 1a can be a prism, and the folding element 1a can change the propagation direction of the optical axis from the first direction to the second direction, and fold the light emitted by the first lens L1 and the second lens L2 and then enter the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a unique two-dimensional plane, that is, the XZ plane.

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

Fig. 24B yes Fig.24A The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. It can be understood that Fig.24A and Fig. 24B The camera module 300 is respectively in a close-range state at the super-telephoto end and a macro state at the super-telephoto end.

[0542] like Fig.23C and Fig.24A As shown, exemplarily, during the zooming process of the camera module 300 from the super telephoto end to the close-up state of 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 of 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 super telephoto end to the close-up state of the super telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 may all be fixed lens groups, and the third lens group G3 may 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 super telephoto end to the close-up state of the super telephoto end, the first lens group G1 and the second lens group G2 may all be fixed lens groups, the third lens group G3 may move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 may move along the direction of the optical axis of the second sub-direction. Specifically, this application does not limit it.

[0544] like Fig.24A and Fig. 24B As shown, exemplarily, in the process of zooming 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 of the second sub-direction. At this time, the distance between the fourth lens group G4 and the third lens group G3 is further increased.

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

[0558]

[0559]

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

[0561]

[0562] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex spherical curvature of the aspheric surface, K is the quadratic surface constant, and A i Substituting the design parameters of the first lens L1 to the eleventh lens L11 and the folding element 1a of the camera module 300 into the above-mentioned aspheric formula, the surface shapes of the object side and image side of the first lens L1 to the eleventh lens L11 of the camera module 300 and the surface shape of the image side of the folding element 1a of the fourth embodiment of the present application can be obtained.

[0563] According to 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] fL fL f1a fL fL fL 45.10 -56.33 141.06 -12.97 63.78 8.14 fL fL f8 fL fL10 fL -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=45.10mm (millimeter), and the first lens L1 can have positive focal power; the focal length fL2 of the second lens L2 satisfies: fL2=-56.33mm, and the second lens L2 can have negative focal power; the focal length f1a of the folding element 1a satisfies: f1a=141.06mm, and the folding element 1a can have positive focal power; the focal length fL3 of the third lens L3 satisfies: fL3=-12.97mm, and the third lens L3 can have negative focal power; the focal length fL4 of the fourth lens L4 satisfies: fL4=63.78mm, and the fourth lens L4 can have positive focal power; the focal length fL5 of the fifth lens L5 satisfies: fL5=8.14mm, and the fifth lens L5 can have positive focal power; The focal length fL6 of the sixth lens L6 satisfies: fL6=-23.22 mm, and the sixth lens L6 may have negative power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-26.49 mm, and the seventh lens L7 may have negative power; the focal length fL8 of the eighth lens L8 satisfies: fL8=17.67 mm, and the eighth lens L8 may have positive power; the focal length fL9 of the ninth lens L9 satisfies: fL9=32.07 mm, and the ninth lens L9 may have positive power; the focal length fL10 of the tenth lens L10 satisfies: fL10=-30.54 mm, and the tenth lens L10 may have negative power; the focal length fL11 of the eleventh lens L11 satisfies: fL11=-27.57 mm, and the tenth lens L10 may have negative 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 matching 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] According to 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 the following Table 4d.

[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 IH 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 together to form a positive and negative lens matching 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] Among them, the focal length ft of the telephoto end of the optical lens 10 and the focal length fs of the super telephoto end of the optical lens 10 satisfy: ft / fs=0.58. It can be understood that by limiting the ratio of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the super telephoto end of the optical lens 10 to be equal to 0.58, the value range of the zoom ratio and zoom magnification of the optical lens 10 is larger, and the optical lens 10 has a larger field of view coverage.

[0576] The optical lens 10 satisfies: fse / fte=1.73. It can be understood that by limiting fse / fte to 1.73, the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can simultaneously achieve a shorter focal length and a longer focal length, which is conducive to achieving the super telephoto end and telephoto end shooting of the optical lens 10.

[0577] Among them, the distance ΔG3 of the third lens group G3 moving along the second direction of the optical axis and the distance ΔG4 of the fourth lens group G4 moving along the second direction of the optical axis satisfy: ΔG4 / ΔG3=1.25. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the third lens group G3 moving along the second direction of the optical axis and the distance ΔG4 of the fourth lens group G4 moving along the second direction of the optical axis to be equal to 1.25, the respective moving strokes of the third lens group G3 and the fourth lens group G4 in the continuous zooming process are close, and the driving mechanism drives the third lens group G3 and the fourth lens group G4 to move with a smaller stroke, which is conducive to realizing the miniaturization of the optical lens 10. At the same time, the structure of the driving mechanism is simpler.

[0578] The focal length f1 of the first lens group G1 and the focal length ft of the telephoto end of the optical lens 10 satisfy: 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 of the telephoto end of the optical lens 10 to be equal to 3.70, 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.

[0579] Among them, 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 accurately controlled, thereby improving the focus 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 accurately controlled, thereby improving the focus 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 be equal to -3.09, 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.

[0585] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt=0.25. It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to be equal to 0.25, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, which is conducive to the optical lens 10 shooting the shooting object in the macro state.

[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 beneficial to realizing the shooting of the shooting object at close range 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 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, and the optical quality of each lens of the optical lens 10 is relatively high, making the image captured by the optical lens 10 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] 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=-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, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 are distributed more reasonably. 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 between aberrations, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be achieved.

[0592] Among them, 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 super telephoto end of the optical lens 10 satisfy: |(ΔG3+ΔG4) / fs|=0.36. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to be equal to 0.36, reducing 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, or increasing the focal length of the corresponding optical lens 10, it is beneficial to realize the miniaturization setting of the optical lens 10.

[0594] like Fig.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.

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

Fig.29B yes Fig.29A The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. Fig.29C yes Fig.29B The camera module 300 shown is a simplified schematic diagram of a partial structure in one embodiment. It can be understood that FIG. 29A to FIG. 29C The camera modules 300 are respectively at the telephoto end, the middle section and the super telephoto end.

[0610] like FIG. 29A to FIG. 29C As shown, the camera module 300 includes a first lens group G1, a second lens group G2, and a stop 5 (attached) arranged in sequence from the object side to the image side. Fig.29A To Attachment Fig.29C ), a third lens group G3, a fourth lens group G4, a filter 30 and an image sensor 20.

[0611] 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.

[0613] like FIG. 29A to FIG. 29CAs shown, 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 infinitely far shooting object, 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 surface in the optical axis direction is fixed. The third lens group G3 and the fourth lens group G4 can move along the optical axis of the first sub-direction of the second direction at the same time, so that the spacing between the second lens group G2 and the third lens group G3 is reduced, and the spacing 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] Exemplarily, 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. Among them, 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 can satisfy: 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 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 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 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 power.

[0616] For example, the folding element 1a can be a reflector, which can change the propagation direction of the optical axis from the first direction to the second direction, and fold the light emitted by the first lens L1 and then incident on the second lens group G2. The optical axis in the first direction and the optical axis in the second direction can form a unique two-dimensional plane, namely the XZ plane.

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

[0632] Among them, the materials of the lenses of 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, and the materials of the second lens L2, the folding element 1a and the sixth lens L6 are all made of glass. It can be understood that by using the resin lens and the glass lens in combination, the camera module 300 can have the characteristics of lighter weight, better durability and excellent 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 of the fifth embodiment

[0635]

[0636]

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

[0638]

[0639] Among them, z is the aspheric height, r is the radial coordinate of the aspheric surface, c is the vertex spherical curvature of the aspheric surface, K is the quadratic surface constant, and A i Substituting the design parameters of the first lens L1 to the ninth lens L9 of the camera module 300 into the above-mentioned aspheric surface formula, the object-side surface and image-side surface shapes of the first lens L1 to the ninth lens L9 of the camera module 300 of 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 the following Table 5c.

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

[0642] fL fL fL fL fL fL fL f8 fL 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=-743.83mm, the fifth lens L5 may have negative power; the focal length fL6 of the sixth lens L6 satisfies: fL6=16.57mm, the sixth lens L6 may have positive power; the focal length fL7 of the seventh lens L7 satisfies: fL7=-23.62mm, the seventh lens L7 may have negative power; the focal length fL8 of the eighth lens L8 satisfies: fL8=19.43mm, the eighth lens L8 may have positive power; the focal length fL9 of the ninth lens L9 satisfies: fL9=-12.53mm, the ninth lens L9 may have negative power.

[0644] 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. According to 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 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 IH 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 together to form a positive and negative lens matching 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] Among them, the focal length ft of the telephoto end of the optical lens 10 and the focal length fs of the super telephoto end of the optical lens 10 satisfy: ft / fs=0.50. It can be understood that by limiting the ratio of the focal length ft of the telephoto end of the optical lens 10 to the focal length fs of the super telephoto end of the optical lens 10 to be equal to 0.50, the value range of the zoom ratio and zoom magnification of the optical lens 10 is larger, and the optical lens 10 has a larger field of view coverage.

[0651] The optical lens 10 satisfies: fse / fte=2.00. It can be understood that by limiting fse / fte to 2.00, the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can simultaneously achieve a shorter focal length and a longer focal length, which is conducive to achieving the super telephoto end and telephoto end shooting of the optical lens 10.

[0652] Among them, the distance ΔG3 of the third lens group G3 moving along the second direction of the optical axis and the distance ΔG4 of the fourth lens group G4 moving along the second direction of the optical axis satisfy: ΔG4 / ΔG3=1.25. It can be understood that by limiting the absolute value of the ratio of the distance ΔG3 of the third lens group G3 moving along the second direction of the optical axis and the distance ΔG4 of the fourth lens group G4 moving along the second direction of the optical axis to be equal to 1.25, the respective moving strokes of the third lens group G3 and the fourth lens group G4 in the continuous zooming process are close, and the driving mechanism drives the third lens group G3 and the fourth lens group G4 to move with a smaller stroke, which is conducive to realizing the miniaturization of the optical lens 10. At the same time, the structure of the driving mechanism is simpler.

[0653] The focal length f1 of the first lens group G1 and the focal length ft of the telephoto end of the optical lens 10 satisfy: 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 of the telephoto end of the optical lens 10 to be equal 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] Among them, 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] 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 accurately controlled, thereby improving the focus 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 be equal to -4.28, 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.

[0661] The magnification Redt of the telephoto end of the optical lens 10 in the macro state satisfies: Redt=0.20. It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in the macro state to be equal to 0.20, the magnification Redt of the telephoto end of the optical lens 10 in the macro state is larger, which is conducive to the optical lens 10 shooting the object in the macro state.

[0662] The magnification Reds of the super telephoto end of the optical lens 10 in the close-up state satisfies: Reds=0.005. It can be understood that by limiting the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state to 0.005, the magnification Reds of the super telephoto end of the optical lens 10 in the close-up state is larger, which is conducive to the optical lens 10 shooting the shooting object at a close distance.

[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 limiting 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 more appropriate, and the optical lens 10 can achieve shooting with a larger 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 smaller and the Abbe number is larger, and the light transmittance of each lens of the optical lens 10 is higher. In this way, the light penetration 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.

[0666] 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 and 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 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.

[0668] Among them, 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 super telephoto end of the optical lens 10 satisfy: |(ΔG3+ΔG4) / fs|=0.342. It can be understood that by limiting |(ΔG3+ΔG4) / fs| to be equal to 0.342, reducing 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, or increasing the focal length of the corresponding optical lens 10, it is beneficial to realize the miniaturization setting of the optical lens 10.
