[0001] The present application claims priority to the Chinese patent application No. 202411089044.6, filed on August 8, 2024, with the State Intellectual Property Office of China, and the Chinese patent application No. 202411089044.6 has the title of “Optical lens, camera module and electronic device”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of lens, in particular to an optical lens, a camera module and an electronic device. BACKGROUND

[0003] With the continuous development of portable electronic devices such as mobile phones, users have higher and higher requirements for the shooting performance of the camera modules of portable electronic devices. The existing camera modules generally use multiple fixed-focus lenses to realize “jump zoom” in cooperation with digital zoom. However, jump zoom cannot meet the shooting needs of users. In addition, the lens positions in the existing fixed-focus lenses using digital zoom are fixed, and the existing fixed-focus lenses also cannot realize optical image stabilization. Therefore, the existing camera modules cannot realize continuous zoom and optical image stabilization at the same time. SUMMARY

[0004] The present application provides an optical lens, a camera module and an electronic device that can realize continuous zoom and optical image stabilization at the same time.

[0005] In a first aspect, the present application provides an optical lens. The optical lens comprises, in order from an object side to an image side, a first lens group, a second lens group, a third lens group and a fourth lens group, the first lens group is used to change the propagation direction of the optical axis from a first direction to a second direction, the first direction is different from the second direction; in the image stabilization process of the optical lens, the first lens group rotates around the first direction, or rotates around the second direction, or rotates around a third direction, or rotates around the first direction and the second direction, or rotates around the second direction and the third direction, or rotates around the first direction and the third direction, or rotates around the first direction, the second direction and the third direction; the third direction is different from the first direction and the second direction; in 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 refractive power, and the second lens group has negative refractive power.

[0006] It can be understood that, in the process of optical image stabilization of the optical lens, the first lens group can rotate around multiple directions, which is beneficial to realize 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 of the second direction, the optical lens can realize continuous zooming. In addition, the third lens group and the fourth lens group are not easy to occupy too much space in the first direction, thereby reducing the length of the optical lens in the first direction, improving the space utilization of the optical lens, and further facilitating the miniaturization of the optical lens. Therefore, the optical lens can realize optical image stabilization and continuous zooming at the same time.

[0007] It can be understood that the first lens group has positive refractive power, and the first lens group can play a role of converging light rays; the second lens group has negative refractive power, and the second lens group can play a role of diverging light rays, and the second lens group can make the field of view angle smaller after diverging the light rays. The first lens group and the second lens group are used in cooperation to form a positive and negative lens cooperation structure, which can better solve the problem of chromatic aberration and other aberrations. On the basis of realizing optical image stabilization and continuous zooming at the same time, the optical lens has higher degree of freedom and better imaging quality.

[0008] It can be understood that, on the basis of the optical lens being capable of realizing optical image stabilization and continuous zooming at the same time, the refractive power configuration mode of the first lens group and the second lens group can be reasonably used, and specific optical lenses with other parameters, such as aspheric surface, focal length, refractive index, system total length of the optical lens, on-axis thickness and radius of curvature, can be reasonably used in cooperation, so that the optical lens can meet the requirements of high zoom ratio and continuous zooming while obtaining high imaging performance.

[0009] In a possible implementation, the second direction includes a first sub-direction and a second sub-direction opposite to each other, and the first sub-direction is a direction in which the third lens group points to the second lens group; in the process of zooming from the long focal end to the super long focal 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 from the super long focal end to the long focal 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.

[0010] It can be understood 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 realize continuous zooming. In addition, the third lens group and the fourth lens group are not easy to occupy too much space in the first direction, thereby reducing the length of the optical lens in the first direction, improving the space utilization of the optical lens, and further facilitating the miniaturization of the optical lens.

[0011] In a possible implementation, during zooming of the optical lens from the super-tele end to the super-tele end micro distance state, the third lens group moves along the first sub-direction, and then the fourth lens group moves along the second sub-direction.

[0012] It can be understood that the optical lens can realize zooming from the super-tele end to the super-tele end micro distance state, can realize continuous zooming, and has good shooting performance in the super-tele end micro distance state.

[0013] In a possible implementation, during zooming of the optical lens from the super-tele end to the super-tele end micro distance state, the third lens group moves along the first sub-direction, and then the fourth lens group moves along the second sub-direction.

[0014] It can be understood that the optical lens can realize zooming from the super-tele end to the super-tele end micro distance state, can realize continuous zooming, and has good shooting performance in the super-tele end micro distance state.

[0015] In a possible implementation, the third lens group has positive refractive power, and the fourth lens group has negative refractive power.

[0016] It can be understood that the third lens group and the fourth lens group can cooperate to realize focusing and zooming 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 cooperation to better solve the problem of chromatic aberration and other aberrations, and the optical lens has higher degrees of freedom and better imaging quality.

[0017] It can be understood that, on the basis of the optical lens being capable of realizing optical image stabilization and continuous zooming at the same time, the optical lens can meet the requirements of high zoom ratio and continuous zooming while obtaining high imaging performance by reasonably using the refractive power configuration mode of the third lens group and the fourth lens group, and by reasonably using the cooperation of specific optical lenses with other parameters, such as aspherical surface, focal length, refractive index, system total optical length of the optical lens, on-axis thickness, and curvature radius.

[0018] In a possible implementation, the optical lens satisfies: 0.2<|ΔG4 / ΔG3|<5, where ΔG3 is the distance of the optical axis movement of the third lens group along the second direction, and ΔG4 is the distance of the optical axis movement of the fourth lens group along the second direction.

[0019] 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 and the distance ΔG3 of the third lens group moving along the optical axis in the second direction to be within the range of 0.2 to 5, the moving stroke of the third lens group and the fourth lens group in the continuous zooming process is close to each other, the stroke of the driving mechanism when driving the third lens group and the fourth lens group to move is small, which is conducive to realizing the miniaturization of the optical lens, and at the same time, the structure of the driving mechanism is simpler and more friendly.

[0020] 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.

[0021] It can be understood that, the smaller the value of |(ΔG3+ΔG4) / fs| is, compared with the same optical lens focal length scheme, 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 smaller; compared with the same third lens group distance ΔG3 of moving along the optical axis in the second direction and the fourth lens group distance ΔG4 of moving along the optical axis in the second direction scheme, the focal length of the optical lens can be larger. In this way, by limiting |(ΔG3+ΔG4) / fs| to be 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, it is conducive to realizing the miniaturization of the optical lens.

[0022] In a possible implementation, the optical lens satisfies: 1.0

[0023] It can be understood that, by limiting the ratio of the focal length f1 of the first lens group and the focal length ft of the telephoto end of the optical lens to be within the range of 1.0 to 5, the optical anti-shake performance of the first lens group is improved, thereby improving the optical anti-shake performance of the optical lens.

[0024] In a possible implementation, the optical lens satisfies: -10

[0025] It can be understood that the smaller the value of f12 / f3 is, the longer the focal lengths of the first lens group and the second lens group are, and the shorter the focal length of the third lens group is, and the larger the value is, the shorter the focal lengths of the first lens group and the second lens group are, and the longer the focal length of the third lens group is. 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 the 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.

[0026] In a possible implementation, the optical lens satisfies: 0.2 < ft / fs < 0.8.

[0027] 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 super-telephoto end of the optical lens within the range of 0.2 to 0.8, the value range of ft / fs is wider, the value range of the zoom ratio and the zoom factor of the optical lens is larger, and the optical lens has a larger field of view coverage.

[0028] 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 of the super-telephoto end of the optical lens, and IHt is the image height of the telephoto end of the optical lens.

[0029] It can be understood that the smaller the value of the zoom ratio fse / fte of the optical lens is, the smaller the zoom ratio is, and the larger the value is, the larger the zoom ratio is. In this way, by limiting the zoom ratio fse / fte of the optical lens within the range of 1 to 5, the value range of the zoom ratio of the optical lens is wider, and the optical lens can simultaneously realize shorter focal lengths and longer focal lengths, which is beneficial to realize the shooting of the super-telephoto end and the telephoto end of the optical lens.

[0030] 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 telephoto end of the optical lens.

[0031] It can be understood that the smaller the value of |ft*(1 / f123t-1 / f12)| is, the lower the focusing sensitivity of the optical lens is, and the larger the value is, the higher the focusing sensitivity of the optical lens is. In this way, by limiting |ft*(1 / f123t-1 / f12)| within the range of less than 5, the focusing of the optical lens can be accurately controlled, and the focusing effect of the optical lens is improved.

[0032] In a possible implementation, the optical lens satisfies: |fs*(1 / f123s-1 / f12)|<5, where f123s is a combined focal length of the first lens group, the second lens group and the third lens group at the super-telephoto end of the optical lens.

[0033] It can be understood that the smaller the value of |fs*(1 / f123s-1 / f12)| is, the lower the focusing sensitivity of the optical lens is, and the larger the value is, the higher the focusing sensitivity of the optical lens is. In this way, by limiting |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 is improved.

[0034] In a possible implementation, the optical lens satisfies: Redt>0.15, where Redt is a magnification of the telephoto end of the optical lens in the macro state.

[0035] It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens in the macro state to be greater than 0.15, the magnification Redt of the telephoto end of the optical lens in the macro state is relatively large, thereby facilitating the shooting of the optical lens on the shooting object in the macro state.

[0036] In a possible implementation, the optical lens satisfies: Reds>0.025, where Reds is a magnification of the super-telephoto end of the optical lens in the close-up state.

[0037] It can be understood that by limiting the magnification Reds of the super-telephoto end of the optical lens in the close-up state to be greater than 0.025, the magnification Reds of the super-telephoto end of the optical lens in the close-up state is relatively large, thereby facilitating the shooting of the optical lens on the shooting object in the close-up state.

[0038] In a possible implementation, the optical lens satisfies: 0.15<Redss<1.0, where Redss is a magnification of the super-telephoto end of the optical lens in the macro state.

[0039] It can be understood that by limiting the magnification Redss of the super-telephoto end of the optical lens in the macro state to be in the range of 0.15 to 1.0, the magnification Redss of the super-telephoto end of the optical lens in the macro state is relatively appropriate, and the optical lens can realize shooting with a relatively large magnification on a relatively far shooting object.

[0040] In a possible implementation, the material of the lens of the optical lens satisfies: 1.4<Nd<2.1, where Nd is a refractive index of the material.

[0041] It can be understood that by limiting the material refractive index Nd of each lens of the optical lens to be within the range of 1.4 to 2.1, the refractive index of each lens of the optical lens is small, the Abbe number is large, and the light transmittance of each lens of the optical lens is high. In this way, the light penetration of each lens of the optical lens is strong, the optical quality of each lens of the optical lens is high, and the image captured by the optical lens is clearer.

[0042] In a possible implementation, the material of the lens of the optical lens satisfies: 15 < Vd < 96, where Vd is the Abbe number.

[0043] It can be understood that by limiting the Abbe number Vd of each lens of the optical lens to be within the range of 15 to 96, the refractive index of each lens of the optical lens is small, the Abbe number is large, and the light transmittance of each lens of the optical lens is high. In this way, the light penetration of each lens of the optical lens is strong, the optical quality of each lens of the optical lens is high, and the image captured by the optical lens is clearer.

[0044] In a possible implementation, the optical lens satisfies: -5 < f2 / fs < 0, where f2 is the focal length of the second lens group.

[0045] It can be understood that the smaller the value of f2 / fs is, the lower the sensitivity of the second lens group is, and the larger the value is, the higher the sensitivity of the second lens group is. In this way, by limiting the ratio of the focal length f2 of the second lens group to the focal length fs of the super-telephoto end of the optical lens to be 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 resolving power of the optical lens is reduced.

[0046] In a possible implementation, the optical lens satisfies: -8 < f1 / f2 < 0.

[0047] It can be understood that by limiting the ratio of the focal length f1 of the first lens group to the focal length f2 of the second lens group to be within the range of -8 to 0, the focal length f1 of the first lens group and the focal length f2 of the second lens group are reasonably distributed. Under this distribution of focal 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 the aberration, volume, cost, and thermal reliability can be achieved, and a wide range of continuous zoom ratios can be implemented.

[0048] In a possible implementation, the first lens group includes one or more lenses and a fold element, at least one of the one or more lenses is located on the object side of the fold element, or the first lens group only includes the fold element, and the fold element has optical power; the fold element is configured to change the propagation direction of the optical axis from a first direction to a second direction.

[0049] It can be understood that the thickness of the optical lens in the first direction can be reduced. In this way, when the optical lens is applied to an electronic device such as a mobile phone, the optical lens is not easy to increase the size of the electronic device in the thickness direction, thereby facilitating the thinness of the electronic device.

[0050] In a possible implementation, the material of the one or more lenses of the first lens group is resin or glass.

[0051] It can be understood that when the material of the one or more lenses of the first lens group is resin, the weight of the lens is small, which facilitates the reduction of the overall weight of the optical lens. In addition, the lens of the one or more lenses of the first lens group has good resistance to vibration and impact. When the material of the lens of the first lens group is glass, the lens of the one or more lenses of the first lens group has excellent optical transparency, refractive index, and chemical stability, and is not easy to scratch or deform, which facilitates the optical lens to realize clear and accurate imaging.

[0052] In a possible implementation, the material of the folding element is resin, glass, or metal.

[0053] It can be understood that when the material of the folding element is resin, the weight of the folding element is light, which facilitates the reduction of 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.

[0054] When the material of the folding element is glass, the folding element has excellent optical performance, which can reduce the optical distortion of the optical lens, and the folding element has good durability and stability, and can perform stably in various use environments.

[0055] When the material of the folding element is metal, the folding element can have high mechanical strength and durability, and metal can effectively conduct heat, so that the folding element is not easy to have a high temperature during work.

[0056] In a possible implementation, the second lens group includes one or more lenses, and the material of the lens of the second lens group is resin or glass.

[0057] It can be understood that when the material of the lens of the second lens group is resin, the weight of the lens of the second lens group is small, which facilitates the reduction of 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 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, and is not easy to scratch or deform, which facilitates the optical lens to realize clear and accurate imaging.

[0058] In a possible implementation, the third lens set includes at least two lenses, and a material of a lens of the third lens set is resin or glass.

[0059] It can be understood that when the material of the lens of the third lens set is resin, the lens of the third lens set has a smaller weight, which is beneficial to reducing the overall weight of the optical lens. In addition, the lens of the third lens set has a better resistance to vibration and impact. For example, when the material of the lens of the third lens set is glass, the lens of the third lens set has excellent optical transparency, refractive index, and chemical stability, and is not easy to scratch or deform, which is beneficial to the optical lens to achieve clear and accurate imaging.

[0060] In a possible implementation, the fourth lens set includes at least two lenses, and a material of a lens of the fourth lens set is resin or glass.

[0061] It can be understood that when the material of the lens of the fourth lens set is resin, the lens of the fourth lens set has a smaller weight, which is beneficial to reducing the overall weight of the optical lens. In addition, the lens of the fourth lens set has a better resistance to vibration and impact. For example, when the material of the lens of the fourth lens set is glass, the lens of the fourth lens set has excellent optical transparency, refractive index, and chemical stability, and is not easy to scratch or deform, which is beneficial to the optical lens to achieve clear and accurate imaging.

[0062] In a possible implementation, the optical lens further includes a diaphragm, the diaphragm is located between the second lens set and the third lens set, or the diaphragm is located inside the second lens set or inside the third lens set.

[0063] It can be understood that when the diaphragm is located between the second lens set and the third lens set, or is located inside the second lens set or inside the third lens set, the diaphragm can achieve a large aperture effect at the telephoto end and the super-telephoto end of the optical lens. In addition, when the diaphragm is located between the second lens set and the third lens set, the diaphragm aberration can be corrected. In addition, the optical lens in the embodiment has a larger number of lenses for correcting aberration, which is beneficial to obtaining better imaging quality.

[0064] In a possible implementation, the optical lens further includes an optical path conversion element, the optical path conversion element is located on an image side of the fourth lens set, and the optical path conversion element is configured to change a propagation direction of an optical axis from the second direction to a fourth direction, the fourth direction being different from the first direction and the second direction.

[0065] It can be understood that the optical path conversion element changes the propagation direction of the optical axis from the second direction to the fourth direction, which is beneficial to folding the optical path, thereby facilitating the miniaturization of the optical lens.

[0066] In a possible implementation, the light turning element is an inclined prism, and an angle a of the minimum acute angle a inside the light turning element satisfies: 17.5°≤a≤37.5°.

[0067] It can be understood that the light turning element can turn the light path, increase the optical length, and improve the imaging quality of the optical lens. The light turning element can also compress the optical size, so that the size of the optical lens in the second direction is reduced, which is beneficial to realize the miniaturization of the optical lens. The angle a of the minimum acute angle a of the light turning element is in a suitable range, so that the included angle between the third direction and the second direction is suitable, which is beneficial to reduce the size of the optical lens in the second direction and the size of the optical lens in the third direction, thereby facilitating the miniaturization of the optical lens.

[0068] In a second aspect, the present application provides a camera module. The camera module includes an image sensor and the optical lens described above, and the image sensor is located on the image side of the optical lens. It can be understood that the camera module can meet the requirements of miniaturization, high zoom ratio and high imaging performance on the basis of simultaneously realizing continuous zooming and optical image stabilization.

The electronic device includes an image processor and the camera module described above, and the image processor is in communication connection with the camera module, and the image processor is configured to acquire image data from the camera module and process the image data. It can be understood that the electronic device can meet the requirements of thinness, high zoom ratio and high imaging performance on the basis of simultaneously realizing continuous zooming and optical image stabilization.

[0136] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0137] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "joint" should be understood broadly, for example, "connection" can be detachable connection, or can be non-detachable connection; can be direct connection, or can be indirect connection through intermediate medium; can be electrical connection, or can be mechanical connection. Among them, "fixed connection" refers to the relative position relationship after being connected with each other. In addition, the two components are integrated by the one-piece forming process, which means that during the formation of one of the two components, the component is connected with the other component, and the two components are connected together without the need for reprocessing (such as bonding, welding, buckling connection, screw connection) method.

[0138] The orientation terms mentioned in the embodiments of the present application, such as "inner", "outer" and the like, are only the direction of the drawings, therefore, the orientation terms used are for better and clearer illustration and understanding of the embodiments of the present application, and are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore, it cannot be understood as a limitation on the embodiments of the present application. For ordinary skilled persons in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0139] 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 particular order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in an "or" relationship. "Multiple" means at least two.

[0140] In order to facilitate the understanding of the optical lens and camera module provided by the embodiments of the present application, the related terms involved in the present application are explained:

[0141] Optical zoom refers to changing the focal length by physically moving the lens to achieve zooming in or out of the captured image. Optical zoom does not easily lose image quality because it changes the physical structure of the lens.

[0142] Focusing refers to adjusting the position of the lens to ensure that the subject is imaged clearly without changing the focal length of the system.

[0143] Optical axis is an axis passing through the center of each lens.

[0144] 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.

[0145] 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.

[0146] Focal length, also known as focal length, is a measure of the convergence or divergence of light in an optical system, which refers to the vertical distance from the optical center of the lens or optical component to the focal plane when an infinite distant object passes through the lens or optical component to form a clear image. 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 the optical center is fixed.

[0147] The focal length of the optical lens is defined as the distance from the center of the optical lens to the focal point.

[0148] Focal power is defined as the difference between the convergence of the image side light beam and the convergence of the object side light beam, which is the reciprocal of the focal length of the lens, and it represents the ability of the optical system to deflect light.

[0149] Positive focal power, also known as positive refractive power, means the lens has a positive focal length, which can converge light.

[0150] Negative focal power, also known as negative refractive power, means the lens has a negative focal length, which can diverge light.

[0151] Telescopic end, the longer focal length section of the lens, the lens has a smaller angle of view, used for shooting distant scenes, especially close-up shots.

[0152] The focal length at the telescopic end (ft) of the camera module is defined as the distance from the center of the telescopic end of the camera module to the focal point.

[0153] Super telescopic end, the longest focal length section of the lens, the lens has the smallest angle of view, used for shooting distant scenes, especially close-up shots.

[0154] The focal length at the super telescopic end (fs) of the camera module is defined as the distance from the center of the super telescopic end of the camera module to the focal point.

[0155] The middle end of the camera module is defined as the intermediate state between the telescopic end and the super telescopic end.

[0156] The focal length at the middle end (fm) of the camera module is defined as the distance from the center of the middle end of the camera module to the focal point.

[0157] Imaging height (IH) is the half of the diagonal length of the effective pixel area on the photosensitive chip, i.e. the radius of the imaging circle.

[0158] Material refractive index (Nd) is defined as the absolute value of the ratio of the propagation speed of light in a material to the speed of light in a vacuum when electromagnetic waves (including visible light) propagate in the material. It is an indicator of the speed and degree of bending of light in a material.

[0159] Abbe number (Vd) is the difference ratio of the refractive index of an optical material at different wavelengths, representing the degree of dispersion of the material.

[0160] Aperture is an entity that restricts the light beam in an optical system. It can be the edge of a lens, a frame or a specially designed screen with holes. Its function can be divided into two aspects: limiting the light beam or limiting the size of the field of view (imaging range). The aperture that limits the light beam most in an optical system is called the aperture stop; the aperture that limits the field of view (size) most is called the field stop.

[0161] Aberration, the optical system near the axial region has the nature of the ideal optical system, a point on the object emitted near the axial rays intersect with the image plane in a point (also known as the near the axial image point), but the actual through the lens aperture of light is difficult to perfect intersection in a point, but with the near the axial image point position has a certain deviation, these differences are collectively referred to as aberration.

[0162] Longitudinal spherical aberration, also known as longitudinal chromatic aberration or position chromatic aberration or axial aberration, a bundle of parallel to the optical axis of light, after passing through the lens will converge in front and back different position, this aberration is called position chromatic aberration or axial aberration. This is due to the different imaging position of each wavelength of light, so that the final imaging of different color light image plane can not coincide, the dispersion of complex color light.

[0163] Distortion, also known as distortion, the distortion degree of the image formed by the optical system relative to the object itself. Distortion is due to the influence of the stop spherical aberration, the intersection height of the chief ray of different field of view through the optical system is not equal to the ideal image height, and 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, which causes the shape of the image to be distorted, but does not affect the clarity of the image.

[0164] Astigmatism, because the object point is not on the optical axis of the optical system, the light beam emitted by it has a tilt angle with the optical axis. After the light beam is refracted by the lens, the convergence points of the meridian pencil and the sagittal pencil are not on the same point. That is, the light beam cannot be focused on a point, and the image is not clear, so astigmatism is generated. Meridian pencil and sagittal pencil are the names of the light beams in the two perpendicular planes in the rotationally symmetric optical system.

[0165] Meridian plane, the plane formed by the chief ray (main light beam) of the off-axis object point and the optical axis, called meridian plane.

[0166] Sagittal surface, the plane passing through the chief ray (main light beam) of the off-axis object point and perpendicular to the meridian plane, called sagittal surface.

[0167] Curvature of field, curvature of field is used to represent the difference between the most clear image point position of the non-central field of view light after passing through the optical lens group and the most clear image point position of the central field of view in the optical axis direction. When the lens has field curvature, the intersection point of the whole light beam does not coincide with the ideal image point, although a clear image point can be obtained at each specific point, but the whole image plane is a curved surface.

[0168] FIG. 1A is a structural schematic diagram of an electronic device 1000 in an embodiment.

[0169] As shown in FIG. 1A, 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 photographing and video shooting functions. The electronic device 1000 in the embodiment shown in FIG. 1A is exemplarily described as a mobile phone.

[0170] FIG. 1B is a partial cross-sectional schematic diagram of the electronic device 1000 shown in FIG. 1A along the line A-A in an embodiment.

[0171] As shown in FIG. 1B, 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 can include more or fewer structures. For example, when the electronic device 1000 includes more structures, the electronic device 1000 can further include a circuit board (not shown in the drawings). When the electronic device 1000 includes fewer structures, the electronic device 1000 can not include the screen 100. It can be understood that FIG. 1A and FIG. 1B only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 1A and FIG. 1B.

[0172] Exemplarily, the screen 100 can be fixed to the housing 200, and the screen 100 can be used to display images to meet the use requirements of a user. The display layer can be a liquid crystal display screen, or an organic light-emitting diode display screen, etc. The screen 100 can be surrounded together with the housing 200 to form an interior of the electronic device 1000. The interior of the electronic device 1000 can be used to place devices of the electronic device 1000, such as a battery, a receiver, or a microphone, etc. The screen 100 can be a flat screen or a curved screen.

[0173] Exemplarily, the camera module 300 can be installed in the housing 200, and the light-in side of the camera module 300 can be arranged to face away from the screen 100 to serve as a rear camera of the electronic device 1000.

[0174] Exemplarily, the shell 200 can have a light-transmitting portion 201, which is not limited to a circular shape as shown in FIG. 1A, but can also be an elliptical shape or an irregular shape. The light-transmitting portion 201 communicates the inside of the electronic device 1000 to the outside of the electronic device 1000. Light outside the electronic device 1000 can enter the inside of the electronic device 1000 through the light-transmitting portion 201, and dust and water can be prevented. The camera module 300 can collect light outside the electronic device 1000 through the light-transmitting portion 201 to realize the shooting of a picture or a video.

[0175] In other embodiments, the light-entering side of the camera module 300 can be directed to the side where the screen 100 is located, as a front-facing camera of the electronic device 1000. Both the front-facing camera and the rear-facing camera can be used for self-shooting, or for a photographer to shoot other objects.

[0176] It can be understood that the mounting position of the camera module 300 of the electronic device 1000 in the embodiment shown in FIG. 1A is only illustrative, and the application does not strictly limit the mounting position of the camera module 300. In some other embodiments, the camera module 300 can also be mounted at other positions of the electronic device 1000, for example, the camera module 300 can be mounted at the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 can include a terminal body and an auxiliary component that can rotate, move or detach relative to the terminal body, and the camera module 300 can also be arranged on the auxiliary component.

[0177] Exemplarily, the image processor 400 can be in communication connection with the camera module 300, and the image processor 400 can be used to acquire 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 such as wiring, or can be realized through coupling and other means. It can be understood that the camera module 300 and the image processor 400 can also be in communication connection through other means capable of realizing data transmission.

[0178] The image processor 400 can include a plurality of processing modules, which can be used to convert the original image signal captured by the camera module 300 to form image information, and transmit the processed information to the display module of the display screen to display the image or video through the display screen. The image processor 400 can 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, and further improve the image quality.

[0179] In the embodiments of the present application, the working principle of the camera module 300 in the electronic device 1000 can be that the light reflected by the photographed object enters the inside of the camera module 300, an optical image is projected onto the surface of the image sensor of the camera module 300, the image sensor converts the optical image into an electrical signal, i.e., an analog image signal, and transmits the converted analog image signal to the analog-to-digital converter 500, so as to be converted into a digital image signal by the analog-to-digital converter 500 and provided to the image processor 400. The image processor 400 can run to convert the original image signal captured by the camera module 300 to form image information, and transmit the processed information to the screen 100 for image or video display. In other embodiments, the electronic device 1000 can further include a memory (not shown in the drawings), and the image processor 400 can transmit the image after processing the image digital signal to the memory, so that the image can be found from the memory at any time when it is needed to view the image and displayed on the screen 100.

[0180] FIG. 1A is only a schematic structural diagram of an electronic device 1000. The size, number and position of the camera module 300, the image processor 400 and the analog-to-digital converter 500 shown in FIG. 1A are only schematic representations, which can be adjusted as needed, and the present application does not limit this.

[0181] It can be understood that the number of camera modules 300 can be one or at least two. When the number of camera modules 300 is one, the camera module 300 can be used as a front camera or a rear camera. When the number of camera modules 300 is at least two, the at least two camera modules 300 can be long-focus camera modules 300, ultra-long-focus camera modules 300, etc., which can meet different shooting requirements, and the present application does not limit this.

[0182] FIG. 2A is a structural schematic diagram of an operation interface of the electronic device 1000 shown in FIG. 1A in an embodiment.

[0183] As shown in FIGS. 1A and 2A, when the user of the electronic device 1000 uses the electronic device 1000 to take a photo, the camera module 300, the image processor 400 and the analog-to-digital converter 500 are in a running state, the light reflected by the photographed object sequentially passes through the collection of the camera module 300, the conversion of the analog-to-digital converter 500 and the conversion of the image processor 400 to form image information, and the image information is displayed on the screen 100. In other embodiments, the shooting operation interface of the electronic device 1000 can also be in other forms. The specific embodiments are not limited by the present application.

[0184] Exemplarily, the user can operate on the screen 100 to issue a running instruction to the electronic device 1000, so as to change 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 can be understood that the camera module 300 can continuously zoom from 1 times to 10 times, or continuously zoom from 10 times to 1 times. In other words, during the continuous zooming 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.

[0185] Exemplarily, when the camera module 300 is at the long focal end, the zoom ratio of the camera module 300 can be 3 times; when the camera module 300 is at the super long focal end, the zoom ratio of the camera module 300 can be 10 times.

[0186] Exemplarily, during the zooming of the camera module 300 from the long focal end to the super long focal end, the zoom ratio of the camera module 300 is continuously changed, for example, when the camera module 300 is at an intermediate state between the long focal end and the super long focal end, the zoom ratio of the camera module 300 can be any value between 3 times and 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 during the zooming of the camera module 300 from the super long focal end to the long focal end, the zoom ratio of the camera module 300 is also continuously changed, and the zoom ratio of the camera module 300 can be any value between 10 times and 3 times.

[0187] It can be understood that during the zooming of the camera module 300 from the long focal end to the super long focal end or from the super long focal end to the long focal end, the camera module 300 can realize continuous zooming within the zooming range, and compared with the scheme of jumping zooming, the imaging clarity of the camera module 300 is better, and the imaging quality of the camera module 300 is higher.

[0188] In other embodiments, the zoom ratio of the camera module 300 can also be other values when the camera module 300 is at the telephoto end, for example, the zoom ratio of the camera module 300 at the telephoto end is 6 times. The zoom ratio of the camera module 300 can also be other values when the camera module 300 is at the super-telephoto end, for example, the zoom ratio of the camera module 300 at the super-telephoto end is 10 times. Meanwhile, the zoom ratio of the camera module 300 can be any value between 6 times and 10 times when the camera module 300 is at an intermediate state between the telephoto end and the super-telephoto end. The specific embodiments of the present application are not limited.

[0189] As shown in FIG. IB, the camera module 300 can include an optical lens 10, an image sensor 20, and a filter 30, for example. Light reflected from the object to be photographed passes through the optical lens 10 by refraction, passes through the filter 30, and is incident on the image sensor 20 to form an image. It can be understood that FIG. IB and the relevant drawings below only schematically show some components included in the camera module 300, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. IB and the drawings below. It can be understood that the camera module 300 can also include fewer or more structures. For example, the camera module 300 can include fewer structures, for example, the camera module 300 can not include the filter 30. The camera module 300 can include more structures, for example, the camera module 300 can also include a lens holder (not shown in the drawings).

[0190] The image sensor 20 can be located on the image side of the optical lens 10. The image sensor 20 is a kind of semiconductor chip, which can also be called a photosensitive chip. The surface of the image sensor 20 contains hundreds of thousands to millions of photodiodes, which will generate electric charges when exposed to light. The image sensor 20 uses the photoelectric conversion function of the photoelectric device to convert the light image on its photosensitive surface into an electric signal in a corresponding proportional relationship with the light image. The photosensitive surface of the image sensor 20 can be arranged to face the optical lens 10. The image sensor 20 can be a charge-coupled device, a complementary metal-oxide semiconductor, a phototransistor, or a thin-film transistor, etc.

[0191] The filter 30 can be located between the optical lens 10 and the image sensor 20, for example. The light rays passing through the optical lens 10 are incident on the filter 30, and the light rays passing through the filter 30 are filtered to form an image on the image sensor 20. The filter 30 can be an infrared filter 30, for example. The filter 30 can eliminate unnecessary waveband light rays projected onto the image sensor 20, prevent the image sensor 20 from producing false colors or moiré, and improve its effective resolution and color reproduction. The specific embodiments of the structure or structure used to achieve filtering are not strictly limited by the present application.

[0192] In some embodiments, the camera module 300 can also cancel the filter 30, and instead achieve filtering by surface treatment or material treatment of 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 used to achieve filtering.

[0193] The following illustrates the implementation scheme of the optical lens 10 in the camera module 300 shown in FIG. 1B.

[0194] As shown in FIG. 1B, the optical lens 10 includes, in order from the object side to the image side, a first lens group G1, a second lens group G2, a third lens group G3, and a fourth lens group G4, and the first lens group G1 is configured 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.

[0195] For example, the first direction can be the Z-axis direction. The second direction can be the X-axis direction. For example, the Z-axis direction can be the thickness direction of the electronic device 1000. The X-axis direction can be the width direction of the electronic device 1000. In other embodiments, the first direction and the second direction are not specifically limited.

[0196] It can be understood that FIG. 1B and the related drawings below only schematically show some components included in the optical lens 10, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 1B and the drawings below. It can be understood that the optical lens 10 can also include fewer or more structures. For example, the optical lens 10 can include more structures, for example, the optical lens 10 can also include a lens holder (not shown in the drawings).

[0197] For example, the first lens group G1 can include one or more lenses and a turning element 1a, and at least one of the one or more lenses is located on the object side of the turning element 1a. The turning element 1a can be configured to change the propagation direction of the optical axis from the first direction to the second direction. During the zooming process of the optical lens 10, the first lens group G1 can be a fixed lens group.

[0198] For example, the turning element 1a can be a prism, a mirror, or other components with a reflecting function. The incident surface and the exit surface of the turning element 1a can be planar, spherical, or aspherical optical surfaces. The specific embodiments of the present application are not limited.

[0199] In other embodiments, the first lens group G1 can not include one or more lenses, and at this time, the first lens group G1 only includes the turning element 1a.

[0200] Exemplarily, the second lens group G2 can include one or more lenses. The second lens group G2 can be a fixed lens group during the zooming of the optical lens 10. In other embodiments, the second lens group G2 can also move along the optical axis of the second direction during the zooming of the optical lens 10.

[0201] Exemplarily, the third lens group G3 can include at least two lenses. The third lens group G3 can move along the optical axis of the second direction during the zooming of the optical lens 10. In this way, the optical lens 10 can realize continuous zooming. In other embodiments, the third lens group G3 can also include one lens. The third lens group G3 can also be a fixed lens group during the zooming of the optical lens 10.

[0202] Exemplarily, the fourth lens group G4 can include at least two lenses. The fourth lens group G4 can move along the optical axis of the second direction during the zooming of the optical lens 10. In this way, the optical lens 10 can realize continuous zooming. In other embodiments, the fourth lens group G4 can also include one lens. The fourth lens group G4 can also be a fixed lens group during the zooming of the optical lens 10.

[0203] It can be understood that, since the third lens group G3 and the fourth lens group G4 can move along the optical axis of the second direction, the optical lens 10 can realize continuous zooming. In addition, the third lens group G3 and the fourth lens group G4 are not easy 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 being conducive to realizing the miniaturization of the optical lens 10. When the optical lens 10 is applied to the electronic device 1000, the electronic device 1000 can realize continuous zooming, and the size of the optical lens 10 in the thickness direction of the electronic device 1000 is smaller, thereby being conducive to realizing the thinness of the electronic device 1000.

[0204] Exemplarily, the camera module 300 can include a driving mechanism (not shown in the drawings), which can be connected with the third lens group G3 and the fourth lens group G4, and can be used to drive the third lens group G3 and the fourth lens group G4 to move along the optical axis of the second direction. It can be understood that, the number of the driving mechanism can also be two, one driving mechanism drives the third lens group G3 to move along the optical axis of the second direction, and the other driving mechanism drives the fourth lens group G4 to move along the optical axis of the second direction. In other embodiments, the number of the driving mechanism can be one, and the driving mechanism is an integrated driving device, which can simultaneously drive the third lens group G3 and the fourth lens group G4 to move along the optical axis of the second direction. The driving mechanism can be a motor, for example, the driving mechanism can be a voice coil motor or a shape memory alloy motor.

[0205] Exemplarily, the first lens group G1 can have positive refractive power, the second lens group G2 can have negative refractive power, the third lens group G3 can have positive refractive power, and the fourth lens group G4 can have negative refractive power.

[0206] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3, and the fourth lens group G4 are used in cooperation to form a positive and negative lens cooperation structure, which can better solve the problem of chromatic aberration and other aberrations, and the optical lens 10 has higher degrees of freedom and better imaging quality.

[0207] It can be understood that the first lens group G1 has positive refractive power and can play a role in converging light rays; the second lens group G2 has negative refractive power and can play a role in diverging light rays, and the second lens group G2 can reduce the field of view angle after diverging the light rays; the third lens group G3 and the fourth lens group G4 can cooperate to realize focusing and zooming of the optical lens 10 and the camera module 300, thereby improving the imaging quality of the optical lens 10 and the camera module 300.

[0208] It can be understood that, on the basis of the optical lens 10 being capable of simultaneously realizing optical image stabilization and continuous zooming, the refractive power configuration mode 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 specific optical lenses with other parameters, such as aspheric surfaces, focal lengths, refractive indices, system optical total length of the optical lens 10, on-axis thickness, and curvature radius, can be reasonably used in cooperation, so that the optical lens 10 can meet the needs of high zoom ratio and continuous zooming while obtaining high imaging performance.

[0209] In other embodiments, the refractive power of the first lens group G1, the refractive power of the second lens group G2, the refractive power of the third lens group G3, and the refractive power of the fourth lens group G4 can all have other settings. The specific embodiments are not limited in the present application.

[0210] In some embodiments, the folding element 1a can not have refractive power. Exemplarily, when the folding element 1a does not have refractive power, the first lens group can further include one or more lenses, and the one or more lenses of the first lens group G1 can be located on the object side of the folding element 1a. At this time, the first lens group G1 is composed of the one or more lenses and the folding element 1a.

[0211] In some embodiments, the folding element 1a can have optical power. It can be appreciated that the folding element 1a with optical power can reduce the number of lenses of the first lens group G1, and can simplify the structural complexity of the first lens group G1, thereby simplifying the structural complexity of the optical lens 10 and the camera module 300. For example, 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 can also not include one or more lenses, and in this case, the first lens group G1 is composed of the folding element 1a.

[0212] For example, the first lens group G1 can have an anti-shake compensation function. For example, in the optical anti-shake process of the optical lens 10, the first lens group G1 can rotate around the first direction, or rotate around the second direction, or rotate around the third direction, or rotate around the first direction and the second direction, or rotate around the second direction and the third direction, or rotate around the first direction and the third direction, or rotate around the first direction, the second direction and the third direction, to realize the optical anti-shake of the optical lens 10, and improve the imaging quality of the optical lens 10. The third direction can be different from the first direction and the second direction.

[0213] For example, the third direction can be in the plane (i.e., the X-Z plane) formed by the first direction and the second direction.

[0214] For example, the third direction can also be perpendicular to the plane formed by the first direction and the second direction. The third direction can be the Y-axis direction. For example, the Y-axis direction can be the length direction of the electronic device 1000.

[0215] It can be appreciated that the optical lens 10 can simultaneously realize continuous zooming and optical anti-shake.

[0216] FIG. 2B is a simplified schematic diagram of the partial structure of the camera module 300 shown in FIG. IB in an embodiment.

[0217] As shown in FIG. 2B, for example, the first lens group G1 can have a first rotation axis O1 and a first rotation center P1.

[0218] For example, the direction of the first rotation axis O1 can be parallel to the first direction. The first rotation axis O1 can pass through the folding element 1a, or can be located outside the folding element 1a. It can be appreciated that the first rotation axis O1 is only schematically shown as a straight line passing through the folding element 1a in FIG. 2B, and the specific position of the first rotation axis O1 is not limited by the position in FIG. 2B.

[0219] Exemplarily, the first rotation center P1 can be at any position on the first rotation axis O1. The first rotation center P1 can be located inside the folding element 1a and at the intersection of the first rotation axis O1 and the folding element 1a, or can be located at any other position inside the folding element 1a, or can be located outside the folding element 1a. It can be understood that the first rotation center P1 is only schematically shown in FIG. 2B as being 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 limited by the position in FIG. 2B.

[0220] It can be understood 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 realize 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.

[0221] As shown in FIG. 2B, exemplarily, the first lens group G1 can have a second rotation axis O2 and a second rotation center P2.

[0222] Exemplarily, the direction of the second rotation axis O2 can be parallel to the second direction, and the second rotation axis O2 can intersect the first rotation axis O1. The second rotation axis O2 can pass through the folding element 1a, or can be located outside the folding element 1a. It can be understood that the second rotation axis O2 is only schematically shown in FIG. 2B as being a straight line passing through the folding element 1a, and the specific position of the second rotation axis O2 is not limited by the position in FIG. 2B.

[0223] Exemplarily, 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 can be located at any other position inside the folding element 1a, or can be located outside the folding element 1a. It can be understood that the second rotation center P2 is only schematically shown in FIG. 2B as being located inside the folding element 1a and at the intersection of the second rotation axis O2 and the folding element 1a, and the specific position of the second rotation center P2 is not limited by the position in FIG. 2B.

[0224] It can be understood that the first lens group G1 can rotate around the second rotation axis O2 with the second rotation center P2 as the rotation center, to realize 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.

[0225] As shown in FIG. 2B, the first lens group G1 can also rotate around a third direction, for example. The third direction can be any direction in the plane (i.e., the X-Z plane) formed by the first direction and the second direction, or a direction perpendicular to the plane formed by the first direction and the second direction. The specific embodiments of the present application are not limited in this regard.

[0226] The first lens group G1 can have a third rotation axis O3 and a third rotation center P3, for example.

[0227] The third rotation axis O3 can be parallel to the third direction, and can intersect with the first rotation axis O1 and the second rotation axis O2 but not be perpendicular to the first rotation axis O1 and the second rotation axis O2, or can intersect with the first rotation axis O1 and the second rotation axis O2 and be perpendicular to the first rotation axis O1 and the second rotation axis O2, or can be parallel to the first rotation axis O1 or the second rotation axis O2. The third rotation axis O3 can pass through the folding element 1a, or can be located outside the folding element 1a. It can be understood that FIG. 2B only schematically shows the third rotation axis O3 as a straight line passing through the folding element 1a and intersecting with the first rotation axis O1 and the second rotation axis O2 and being perpendicular to the first rotation axis O1 and the second rotation axis O2, and the specific position of the third rotation axis O3 is not limited by the position in FIG. 2B.

[0228] The third rotation center P3 can be at any position on the third rotation axis O3, and can be located inside the folding element 1a at the intersection of the third rotation axis O3 and the folding element 1a, or can be at any other position inside the folding element 1a, or can be located outside the folding element 1a. It can be understood that FIG. 2B only schematically shows the third rotation center P3 located outside the folding element 1a, and the specific position of the third rotation center P3 is not limited by FIG. 2B.

[0229] It can be understood that the first lens group G1 can rotate around the third rotation axis O3 with the third rotation center P3 as the rotation center, to achieve optical image stabilization of the optical lens 10 and the camera module 300, thereby improving the imaging quality of the optical lens 10 and the camera module 300.

[0230] As shown in FIG. 2B, 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 ≤ 10 mm (millimeters), for example, d can be equal to 0.5 mm, 1 mm, 1.4 mm, 2.8 mm, 3.3 mm, 4.8 mm, 5 mm, 6.67 mm, 7 mm, 8.88 mm, 9.5 mm, or 10 mm. It can be understood that when the first lens group G1 rotates around this third direction, the optical image stabilization effect of the optical lens 10 is better.

[0231] 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.

[0232] In other embodiments, the distance d between the intersection of the first direction and the second direction and the third direction can also satisfy other ranges. The specific embodiments are not limited herein.

[0233] Exemplarily, the anti-shake driving mechanism can also be connected with the first lens group G1, and the anti-shake driving mechanism can be used to drive the first lens group G1 to move to realize the optical image stabilization 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 can 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 can be flexibly adjusted according to actual needs, and the specific embodiments are not limited herein.

[0234] FIG. 3A is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. IB in an embodiment. FIG. 3B is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. 3A in an embodiment. FIG. 3C is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. 3B in an embodiment. It can be understood that the camera module 300 in FIGS. 3A-3C is at the telephoto end, the intermediate section and the super-telephoto end respectively.

[0235] As shown in FIGS. 3A-3C, exemplarily, the second direction includes a first sub-direction and a second sub-direction which are opposite directions, the first sub-direction can be a direction in which the third lens group G3 points to the second lens group G2, and the second sub-direction can be a direction in which the second lens group G2 points 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 a direction in which the second lens group G2 points to the third lens group G3, and the second sub-direction can also be a direction in which the third lens group G3 points 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 specific embodiments are not limited herein.

[0236] As shown in FIGS. 3A-3C, exemplarily, in the process of zooming from the telephoto end to the super-telephoto end of the optical lens 10, 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 decreases. When the optical lens 10 is at the super-telephoto end, the optical lens 10 can focus on a far distance shooting object (also including a user using the optical lens 10).

[0237] As shown in FIGS. 3A-3C, exemplarily, in the process of zooming from the super-telephoto end to the telephoto end of the optical lens 10, 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 a close distance or even a macro shooting object (also including a user using the optical lens 10).

[0238] It can be understood 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 realize continuous zooming. In addition, the third lens group G3 and the fourth lens group G4 are not easy 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 further 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 realize continuous zooming, and the size of the optical lens 10 in the thickness direction of the electronic device 1000 is smaller, thereby facilitating the thinness of the electronic device 1000.

[0239] As shown in FIG. 1B, the optical lens 10 can further include a diaphragm 5. Exemplarily, the diaphragm 5 can be located between every two lenses.

[0240] Exemplarily, the diaphragm 5 can be an aperture diaphragm, 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 imaging. In other embodiments, the position of the diaphragm 5 is not limited to the diaphragm 5 located between the second lens group G2 and the third lens group G3 as shown in FIG. 1B. The diaphragm 5 can also be located inside the second lens group G2 or inside the third lens group G3, and the position of the diaphragm 5 can be flexibly adjusted according to actual needs.

[0241] It can be understood that when the diaphragm 5 is located between the second lens group G2 and the third lens group G3, or when the diaphragm 5 is located inside the second lens group G2 or inside the third lens group G3, the diaphragm 5 can achieve the effect of a large aperture for both the telephoto end and the super-telephoto end of the optical lens 10. In addition, when the diaphragm 5 is located between the second lens group G2 and the third lens group G3, it is convenient to correct the aberration of the diaphragm 5. In addition, the optical lens 10 of the present embodiment has a large number of lenses for correcting aberration, which is beneficial to obtaining better imaging quality.

[0242] In other embodiments, the optical lens 10 can also not include the diaphragm 5. It can be understood that FIG. 1B only schematically shows some components of the optical lens 10, and the actual shape, actual size and actual structure of these components are not limited by FIG. 1B.

[0243] Some specific but non-limiting examples of the embodiments of the present application will be described in more detail below in conjunction with the relevant drawings.

[0244] The first embodiment: FIG. 4A is a simplified schematic diagram of the partial structure of the camera module 300 shown in FIG. 3C in an embodiment. FIG. 4B is a simplified schematic diagram of the partial structure of the camera module 300 shown in FIG. 4A in an embodiment. It can be understood that the camera module 300 in FIG. 4A and FIG. 4B is in the close-up state of the super-telephoto end and the macro state of the super-telephoto end, respectively.

[0245] As shown in FIG. 3C and FIG. 4A, for example, during the process of the camera module 300 zooming 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 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.

[0246] In some embodiments, during the process of the camera module 300 zooming 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. In other embodiments, the camera module 300 has sufficient space inside, the distance between the second lens group G2 and the third lens group G3 is large, and the distance between the fourth lens group G4 and the optical filter 30 is large, during the process of the camera module 300 zooming 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 can all be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. The specific application is not limited.

[0247] As shown in FIGS. 4A and 4B, 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 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.

[0248] In some embodiments, 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 fourth lens group G4 can be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the camera module 300 has sufficient space inside, the distance between the second lens group G2 and the third lens group G3 is large, and the distance between the fourth lens group G4 and the filter 30 is large, 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 and the second lens group G2 can be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. The specific embodiments of the present application are not limited.

[0249] FIG. 5 is a simplified schematic diagram of part of the camera module 300 shown in FIG. 3A in another embodiment. It can be understood that the camera module 300 in FIG. 5 is in the macro state at the telephoto end.

[0250] As shown in FIGS. 3A and 5, 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 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.

[0251] In some embodiments, during the process that the camera module 300 zooms from the telephoto end to the macro state of the long focal end, the first lens group G1, the second lens group G2 and the third lens group G3 can be fixed lens groups, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. In other embodiments, the camera module 300 has sufficient space inside, the distance between the second lens group G2 and the third lens group G3 is large, and the distance between the fourth lens group G4 and the filter 30 is large. During the process that the camera module 300 zooms from the telephoto end to the macro state of the long focal end, the first lens group G1 and the second lens group G2 can be fixed lens groups, the third lens group G3 can move along the direction of the optical axis of the first sub-direction, and the fourth lens group G4 can move along the direction of the optical axis of the second sub-direction. The specific application is not limited.

[0252] The structure of the optical lens 10 is specifically described above in combination with the related drawings. The setting of the related optical parameters of the optical lens 10 will be specifically described below in combination with the drawings.

[0253] Exemplarily, the optical lens 10 can satisfy: 0.2<|ΔG4 / ΔG3|<5, where ΔG3 is the distance of the movement of the third lens group G3 along the optical axis of the second direction, ΔG4 is the distance of the movement of the fourth lens group G4 along the optical axis of 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.

[0254] It can be understood that by limiting the absolute value of the ratio of the distance ΔG4 of the movement of the fourth lens group G4 along the optical axis of the second direction and the distance ΔG3 of the movement of the third lens group G3 along the optical axis of the second direction to be within the range of 0.2 to 5, the moving distances of the third lens group G3 and the fourth lens group G4 in the continuous zooming process are close to each other, the stroke of the driving mechanism when driving the third lens group G3 and the fourth lens group G4 to move is small, which is conducive to the miniaturization of the optical lens 10, and at the same time, the structure of the driving mechanism is simpler and more friendly.

[0255] In other embodiments, the ratio |ΔG4 / ΔG3| of the distance ΔG4 of the movement of the fourth lens group G4 along the optical axis of the second direction and the distance ΔG3 of the movement of the third lens group G3 along the optical axis of the second direction can also satisfy other ranges. The specific application is not limited.

[0256] It can be understood that, in the following, 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 when the third lens group G3 and the fourth lens group G4 move along the optical axis of the second direction to the object side, 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 along the optical axis of the second direction to the image side, 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 of ΔG3 and ΔG4 can be flexibly set according to actual needs.

[0257] Exemplarily, the optical lens 10 can satisfy: |(ΔG3+ΔG4) / fs|<5, for example, |(ΔG3+ΔG4) / fs| can be equal to 0.5, 1, 1.8, 2.3, 3, 3.6, 4.2 or 4.9, etc. It can be understood that, the smaller the value of |(ΔG3+ΔG4) / fs| is, compared with the same focal length of the optical lens 10, the distance ΔG3 of the third lens group G3 moving along the optical axis of the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis of the second direction can be smaller; compared with the same distance ΔG3 of the third lens group G3 moving along the optical axis of the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis of the second direction, the focal length of the optical lens 10 can be larger. In this way, by limiting |(ΔG3+ΔG4) / fs| in the range of less than 5, reducing the distance ΔG3 of the third lens group G3 moving along the optical axis of the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis of the second direction, or increasing the focal length of the corresponding optical lens 10, it is beneficial to realize the miniaturization of the optical lens 10.

[0258] In other embodiments, |(ΔG3+ΔG4) / fs| can also satisfy other ranges. Specifically, the present application is not limited.

[0259] Exemplarily, the optical lens 10 can satisfy: 0.2<ft / fs<0.8, wherein ft is the focal length of the telephoto end of the optical lens 10, fs is the focal length of the super-telephoto end of the optical lens 10, and ft / fs can be equal to 0.21, 0.23, 0.38, 0.4, 0.5, 0.66, 0.7 or 0.79, etc. It can be understood that, by 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 in the range of 0.2 to 0.8, the range of ft / fs is wide, the zoom ratio and the zoom factor of the optical lens 10 have a larger range, and the optical lens 10 has a larger field of view coverage.

[0260] In other embodiments, 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 ft / fs can also satisfy other ranges. The present application does not limit specifically.

[0261] Exemplarily, the optical lens 10 can satisfy:

[0262] 1 < fse / fte < 5, wherein fse = (fs x 43.27) / IHs, fte = (ft x 43.27) / IHt, IHs is the image height of the super-telephoto end of the optical lens 10, and IHt is the image height of 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. In this way, by limiting 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 wide, and the optical lens 10 can realize both shorter focal length and longer focal length, which is beneficial to realize the shooting of the super-telephoto end and the telephoto end of the optical lens 10.

[0263] In other embodiments, 1 < fse / fte < 5 can also satisfy other ranges. The present application does not limit specifically.

[0264] Exemplarily, the optical lens 10 can satisfy: 1.0 < f1 / ft < 5, wherein 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 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 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.

[0265] 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. The present application does not limit specifically.

[0266] 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)| is, the lower the focusing sensitivity of the optical lens 10 is, and the larger the value is, the higher the focusing sensitivity of the optical lens 10 is. In this way, by limiting |ft×(1 / f123t-1 / f12)| to be 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.

[0267] In other embodiments, |ft×(1 / f123t-1 / f12)| can also satisfy other ranges. Specifically, the present application is not limited.

[0268] 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 super-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)| is, the lower the focusing sensitivity of the optical lens 10 is, and the larger the value is, the higher the focusing sensitivity of the optical lens 10 is. In this way, by limiting |fs×(1 / f123s-1 / f12)| to be 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.

[0269] In other embodiments, |fs×(1 / f123s-1 / f12)| can also satisfy other ranges. Specifically, the present application is not limited.

[0270] 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 is, the longer the focal length of the first lens group G1 and the second lens group G2 are, and the shorter the focal length of the third lens group G3 is, and the larger the value is, the shorter the focal length of the first lens group G1 and the second lens group G2 are, and the longer the focal length of the third lens group G3 is. In this way, 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 within the 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.

[0271] 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. The specific embodiments are not limited herein.

[0275] In other embodiments, the magnification of the optical lens 10 at the super-telephoto end in the close-up state (Reds) can also satisfy other ranges. The application does not limit the magnification of the optical lens 10 at the super-telephoto end in the close-up state (Reds) specifically.

[0276] Exemplarily, when the optical lens 10 is at the super-telephoto end, the fourth lens group G4 can move away from the first lens group G1 and the second lens group G2. The optical lens 10 can satisfy: 0.15 < Redss < 1.0, where Redss is the magnification of the optical lens 10 at the super-telephoto end 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 limiting the magnification of the optical lens 10 at the super-telephoto end in the macro state (Redss) to be within the range of 0.15 to 1.0, the magnification of the optical lens 10 at the super-telephoto end in the macro state (Redss) is more appropriate, and the optical lens 10 can achieve a larger magnification for a relatively far shooting object.

[0277] In other embodiments, the magnification of the optical lens 10 at the super-telephoto end in the close-up state (Reds) can also satisfy other ranges. The application does not limit the magnification of the optical lens 10 at the super-telephoto end in the close-up state (Reds) specifically.

[0295] Exemplarily, the lens material of the lenses of the fourth lens group G4 can also be glass. It can be understood that the lens lenses of the fourth lens group G4 have excellent optical transparency, refractive index, and chemical stability, are not easily scratched or deformed, which is conducive to the optical lens 10 achieving clear and accurate imaging.

In this way, by limiting the ratio of the focal length f2 of the second lens group G2 to the focal length fs of the super-telephoto 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 resolving power of the optical lens 10 is reduced.

Under this distribution of focal power, by reasonably setting the refractive index, Abbe number, shape, thickness, air gap of the lenses in each lens group, a good balance between aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be achieved.

[0302] 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. The specific embodiments are not limited herein.

[0387] 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 resin, and the materials of the second lens L2, the folding element 1a, the sixth lens L6, and the filter 30 are glass. It can be understood that by using the resin lenses and the glass lenses together, the camera module 300 can have the characteristics of light weight, good durability, and excellent optical performance.

[0388] In addition, the aspheric coefficients of the lenses of the camera module 300 of the second embodiment of the present application are as shown in Table 2b.

[0390] It can be understood that among the 18 aspheric surfaces of the camera module 300 shown in Table 2a and Table 2b, all the even and odd aspheric surface types z can be defined by, but not limited to, the following aspheric formula:

[0391] wherein z is the sag of the aspheric surface, r is the radial coordinate of the aspheric surface, c is the vertex spherical curvature of the aspheric surface, K is the conic constant, A i represents the i-th order aspheric coefficient. By 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 surface types of the object side and the image side 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.

[0396] According to the data in Table 2a and Table 2b, part of the parameters of the camera module 300 of the second embodiment of the application can be obtained, and are specifically shown in Table 2d.

[0397] Table 2d Part of the parameters of the camera module 300 of the second embodiment

[0398] It can be understood that the setting ranges of the related optical parameters in the embodiment can refer to the setting ranges of the related optical parameters in the first embodiment.

[0399] It can be understood that the focal length f1 of the first lens group G1 satisfies: f1 = 56.96 mm, and the first lens group G1 can have positive refractive power; the focal length f2 of the second lens group G2 satisfies: f2 = -21.95 mm, and the second lens group G2 can have negative refractive power; the focal length f3 of the third lens group G3 satisfies: f3 = 10.85 mm, and the third lens group G3 can have positive refractive power; and the focal length f4 of the fourth lens group G4 satisfies: f4 = -12.37 mm, and the fourth lens group G4 can have negative refractive power.

[0400] It can be understood that the first lens group G1, the second lens group G2, the third lens group G3 and the fourth lens group G4 are used in cooperation to form a positive and negative lens cooperation structure, which can better solve the problem of chromatic aberration and other aberrations, the optical lens 10 has higher degree of freedom, and the imaging quality is better.

[0401] Wherein, the focal length ft of the long focal end of the optical lens 10 and the focal length fs of the super long focal 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 long focal end of the optical lens 10 and the focal length fs of the super long focal end of the optical lens 10 to be equal to 0.76, the value range of the zoom ratio and the zoom factor of the optical lens 10 is larger, and the optical lens 10 has a larger field of view coverage.

[0402] Wherein, the optical lens 10 satisfies: fse / fte=2.64. It can be understood that by limiting fse / fte to be equal to 2.64, the value of the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can realize shorter focal length and longer focal length at the same time, which is beneficial to realize the shooting of the super long focal end and the long focal end of the optical lens 10.

[0403] Wherein, the distance ΔG3 of the third lens group G3 moving along the optical axis of the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis of 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 third lens group G3 moving along the optical axis of the second direction and the distance ΔG4 of the fourth lens group G4 moving along the optical axis of the second direction to be equal to 1.45, the moving distance of the third lens group G3 and the fourth lens group G4 is close to each other in the continuous zooming process, and the driving mechanism has smaller stroke when driving the third lens group G3 and the fourth lens group G4 to move, which is beneficial to realize the miniaturization of the optical lens 10, and the structure of the driving mechanism is simpler.

[0404] Wherein, the focal length f1 of the first lens group G1 and the focal length ft of the long focal 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 and the focal length ft of the long focal 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.

[0405] Wherein, the focal length ft of the long focal 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 long focal 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:

[0406] |ft×(1 / f123t-1 / f12)|=1.90. It is understandable that by limiting |ft×(1 / f123t-1 / f12)| to 1.90, the focusing of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0407] Wherein, 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 the following:

[0408] |fs×(1 / f123s-1 / f12)|=2.37. It can be understood that by limiting |fs×(1 / f123s-1 / f12)| to 2.37, the focusing of the optical lens 10 can be precisely controlled, thereby improving the focusing effect of the optical lens 10.

[0409] 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 the following:

[0410] f12 / f3 = -5.41. It can be understood that by limiting the ratio of the combined focal length f12 of the first lens group G1 and the second lens group G2 to the focal length f3 of the third lens group G3 to -5.41, the optical image stabilization performance of the first lens group G1 is improved, thereby improving the optical image stabilization performance of the optical lens 10.

[0411] Specifically, the magnification Redt of the telephoto end of the optical lens 10 in macro mode satisfies: Redt = 0.39. It can be understood that by limiting the magnification Redt of the telephoto end of the optical lens 10 in macro mode to 0.39, the magnification Redt of the telephoto end of the optical lens 10 in macro mode is relatively large, which is beneficial for enabling the optical lens 10 to capture macro subjects.

[0412] Specifically, the magnification Reds of the super-telephoto end of the optical lens 10 at close range satisfies: Reds = 0.03. It can be understood that by limiting the magnification Reds of the super-telephoto end of the optical lens 10 at close range to 0.03, the magnification Reds of the super-telephoto end of the optical lens 10 at close range is relatively large, which is beneficial for enabling the optical lens 10 to capture subjects at close range.

[0413] The magnification Redss of the optical lens 10 at the super-telephoto end in the macro state satisfies: Redss = 0.23. It can be understood that by limiting the magnification Redss of the optical lens 10 at the super-telephoto end in the macro state to be equal to 0.23, the magnification Redss of the optical lens 10 at the super-telephoto end in the macro state is more appropriate, and the optical lens 10 can achieve a larger magnification for a relatively far shooting object.

[0414] The material refractive index Nd of each lens of the optical lens 10 and the Abbe number Vd of each lens of the optical lens 10 satisfy: 1.50 < Nd < 1.80, 20.4 < Vd < 81.56. It can be understood that by limiting the material refractive index Nd of each lens of the optical lens 10 to be in the range of 1.50 to 1.80, and limiting the Abbe number Vd of each lens of the optical lens 10 to be in the range of 20.4 to 81.56, the refractive index of each lens of the optical lens 10 is smaller, the Abbe number is larger, and the transmittance of the lens of each lens of the optical lens 10 is higher. In this way, the light transmittance of the lens of each lens of the optical lens 10 is stronger, and the optical quality of each lens of the optical lens 10 is higher, so that the image captured by the optical lens 10 is clearer.

[0415] The focal length f2 of the second lens group G2 and the focal length fs of the super-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.71. It can be understood that by limiting the ratio of the focal length f2 of the second lens group G2 and the focal length fs of the super-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 resolving power of the optical lens 10 is reduced.

[0416] The focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 satisfy: f1 / f2 = -2.59. It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 to be equal to -2.59, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 are reasonably distributed. Under this distribution of focal power, by reasonably setting the refractive index, Abbe number, shape, thickness, air gap of the lenses in each lens group, a good balance between aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be achieved.

[0417] The distance AG3 of the third lens group G3 moving along the optical axis in the second direction, the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction, and the focal length fs of the tele end of the optical lens 10 satisfy: |(AG3+AG4) / fs|=0.23. It can be understood that by limiting |(AG3+AG4) / fs| to be equal to 0.23, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction and the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, which is conducive to the miniaturization of the optical lens 10.

[0427] As shown in FIG. 14A, 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 the picture is not obviously deformed, the optical distortion degree of the image is small, and the imaging quality of the camera module 300 is high.

[0428] FIG. 14B is a simulation effect diagram three of the super-telephoto end of the camera module 300 of the second embodiment.

[0429] As shown in FIG. 14B, 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 the picture is not obviously deformed, the optical distortion degree of the image is small, and the imaging quality of the camera module 300 is high.

[0430] The third embodiment: FIG. 15A is a partial structure simplified schematic diagram three of the camera module 300 shown in FIG. 1B in an embodiment. FIG. 15B is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. 15A in an embodiment. FIG. 15C is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. 15B in an embodiment. It can be understood that the camera module 300 in FIG. 15A to FIG. 15C is at the telephoto end, the middle section and the super-telephoto end respectively.

[0431] As shown in FIG. 15A to FIG. 15C, exemplarily, the camera module 300 includes, arranged in order from the object side to the image side, a first lens group G1, a second lens group G2, a diaphragm 5 (not shown in FIG. 15A to FIG. 15C), a third lens group G3, a fourth lens group G4, a light conversion element 6, a filter 30 and an image sensor 20.

[0432] Exemplarily, the first lens group G1 includes a first lens L1 and a turning 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.

[0433] 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 refractive power. The second lens L2, the fourth lens L4, the seventh lens L7 and the ninth lens L9 can all have negative refractive power.

[0434] As shown in FIGS. 15A-15C, the light turning element 6 can be located on the image side of the fourth lens group G4. The light turning element 6 can change the propagation direction of the optical axis from the second direction to a fourth direction. The fourth direction is different from the first direction and the second direction. In this case, the filter 30 and the image sensor 20 can be arranged to face the exit surface of the light turning element 6.

[0435] The light turning element 6 can be a component such as a bevel prism, a right-angle prism, or a mirror that can realize a reflection function. In other embodiments, the light turning element 6 can have other structures. The specific embodiments are not limited in this regard.

[0436] The light turning element 6 can fold the optical axis in the second direction to a certain angle. It can be understood that the light turning element 6 can fold the optical path to increase the optical length and improve the imaging quality of the optical lens 10. The light turning 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 beneficial to realize the miniaturization of the optical lens 10 and the camera module 300.

[0437] When the light turning element 6 is a bevel prism, the light turning element 6 can satisfy 17.5°≤a≤37.5°, where a is the angle a of the minimum acute angle a of the light turning element 6. For example, a can be equal to 17.5°, 18.36°, 22°, 24°, 27.5°, 29.5°, 33°, 36.1°, or 37.5°. It can be understood that the range of the angle a of the minimum acute angle a of the light turning element 6 is appropriate, so that the included angle between the third direction and the second direction is appropriate, which is beneficial to reduce 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.

[0438] In other embodiments, the angle a of the minimum acute angle a of the light turning element 6 can also satisfy other ranges.

[0439] It can be understood that the relative position of the light turning element 6 in the camera module 300 is only schematically shown by a rectangle in FIGS. 15A-15C, and the shape of the actual light turning element 6 and the direction of the optical axis are not limited by FIGS. 15A-15C.

[0440] As shown in FIGS. 15A-15C, exemplarily, when the optical lens 10 continuously zooms from the telephoto end to the intermediate section, then continuously zooms to the super-telephoto end, and focuses on the shooting object at infinity, the first lens group G1 and the second lens group G2 are fixed lens groups, and the first lens group G1 is fixed in the position relative to the imaging surface in the optical axis direction. The third lens group G3 and the fourth lens group G4 can simultaneously move along the optical axis in the first sub-direction of the second direction, so that the distance between the second lens group G2 and the third lens group G3 decreases, the distance between the third lens group G3 and the fourth lens group G4 decreases, and the optical zoom ratio of the optical lens 10 can be in the range of 3X-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 ranges.

[0441] Exemplarily, when the optical lens 10 is at a shorter focal length, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction and the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction are both small; when the optical lens 10 is at a longer focal length, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction and the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction are both large. Wherein, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction is less than the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction, that is, the third lens group G3 and the fourth lens group G4 can satisfy: AG3< AG4.

[0442] Exemplarily, the focal length f1 of the first lens group G1 satisfies: f1> 0, that is, the first lens group G1 can have positive refractive power. Exemplarily, the focal length f2 of the second lens group G2 can satisfy: f2< 0, that is, the second lens group G2 can have negative refractive power. The focal length f3 of the third lens group G3 can satisfy: f3> 0, that is, the third lens group G3 can have positive refractive power. The focal length f4 of the fourth lens group G4 can satisfy: f4< 0, that is, the fourth lens group G4 can have negative refractive power.

[0443] Exemplarily, the turning 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 turn the light rays emitted by the first lens L1 to be incident on the second lens group G2. Wherein, the optical axis of the first direction and the optical axis of the second direction can form a unique two-dimensional plane, that is, the X-Z plane.

[0444] Exemplarily, the first lens group G1 has an anti-shake compensation function, and can realize optical anti-shake of the optical lens 10. In the process of optical anti-shake of the optical lens 10, the first lens group G1 can rotate around the first direction, can rotate around the second direction, or can rotate around the third direction.

[0445] FIG. 16A is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. 15C in an embodiment. FIG. 16B is a partial structure simplified schematic diagram of the camera module 300 shown in FIG. 16A in an embodiment. It can be understood that the camera module 300 in FIG. 16A and FIG. 16B is in the close-up state of the super-telephoto end and the macro state of the super-telephoto end, respectively.

[0446] As shown in FIG. 15C and FIG. 16A, exemplarily, in the process of zooming 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 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 increased.

[0447] In some embodiments, in the process of zooming 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 can be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the camera module 300 has sufficient space inside, the distance between the second lens group G2 and the third lens group G3 is large, and the distance between the fourth lens group G4 and the filter 30 is large, in the process of zooming 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 can be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. The specific embodiments of the present application are not limited.

[0448] As shown in FIG. 16A and FIG. 16B, exemplarily, in the process of zooming the camera module 300 from the close-up state of the super-telephoto end to the macro state of the super-telephoto end, the first lens group G1, the second lens group G2 and the third lens group G3 can 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.

[0449] In some embodiments, during zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the camera module 300 has sufficient space inside, the distance between the second lens group G2 and the third lens group G3 is large, and the distance between the fourth lens group G4 and the filter 30 is large. During zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1 and the second lens group G2 can be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. The specific embodiments are not limited herein.

[0450] It can be understood that the relative positions of the light turning element 6 in the camera module 300 are only schematically shown by rectangles in FIGS. 16A and 16B, and the actual shape of the light turning element 6 and the direction of the optical axis are not limited by FIGS. 16A and 16B.

[0451] FIG. 17 is a simplified schematic diagram of part of the camera module 300 shown in FIG. 15A in another embodiment. It can be understood that the camera module 300 in FIG. 17 is in the macro state at the telephoto end.

[0452] As shown in FIGS. 15A and 17, for example, during zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can 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.

[0453] In some embodiments, during zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1, the second lens group G2, and the fourth lens group G4 can be fixed lens groups, and the third lens group G3 can move along the optical axis of the first sub-direction. In other embodiments, the camera module 300 has sufficient space inside, the distance between the second lens group G2 and the third lens group G3 is large, and the distance between the fourth lens group G4 and the filter 30 is large. During zooming of the camera module 300 from the telephoto end to the macro state at the telephoto end, the first lens group G1 and the second lens group G2 can be fixed lens groups, the third lens group G3 can move along the optical axis of the first sub-direction, and the fourth lens group G4 can move along the optical axis of the second sub-direction. The specific embodiments are not limited herein.

[0454] It can be understood that the relative position of the light turning element 6 in the camera module 300 is only schematically shown by the rectangle in FIG. 17, and the actual shape of the light turning element 6 and the direction of the optical axis are not limited by FIG. 17.

[0481] 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.

[0482] Wherein, 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, thereby facilitating the shooting of the optical lens 10 on the shooting object in the macro state.

[0483] Wherein, 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 be equal to 0.03, 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 shooting of the optical lens 10 on the shooting object in the close-up state.

[0484] Wherein, the magnification Redss of the super-telephoto end of the optical lens 10 in the macro state satisfies: Redss=0.18.

It can be understood that by limiting the material refractive index Nd of each lens of the optical lens 10 to be within the range of 1.44 to 1.91, and limiting 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 small, the Abbe number is large, and the transmittance of the lens of each lens of the optical lens 10 is high. In this way, the light transmittance of the lens of each lens of the optical lens 10 is strong, the optical quality of each lens of the optical lens 10 is high, and the image captured by the optical lens 10 is clearer.

[0486] The focal length f2 of the second lens group G2 and the focal length fs of the super-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.34. It can be understood that by limiting the ratio of the focal length f2 of the second lens group G2 and the focal length fs of the super-telephoto 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 resolving power of the optical lens 10 is reduced.

[0487] 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 limiting the ratio of the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 to be equal to -3.25, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 are reasonably distributed. Under this distribution of focal power, by reasonably setting the refractive index, Abbe number, shape, thickness, air gap of the lenses in each lens group, a good balance between aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be achieved.

It can be understood that by limiting |(ΔG3+ΔG4) / fs| to be equal to 0.21, 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 are reduced, or the focal length of the corresponding optical lens 10 is increased, which is beneficial to the miniaturization of the optical lens 10.

[0542] Wherein, the optical lens 10 satisfies: fse / fte = 1.73. It can be understood that by limiting fse / fte to be equal to 1.73, the value of the zoom ratio of the optical lens 10 is more appropriate, and the optical lens 10 can realize shorter focal length and longer focal length at the same time, which is beneficial to realize the shooting of the super long focal end and the long focal end of the optical lens 10.

[0544] Wherein, 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 and 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.

[0546] |ft×(1 / f123t-1 / f12)|=1.858. It can be understood that by limiting |ft×(1 / f123t-1 / f12)| to be equal to 1.858, the focusing of the optical lens 10 can be accurately controlled, thereby improving the focusing effect of the optical lens 10.

[0547] Wherein, the focal length fs of 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:

[0548] |fs×(1 / f123s-1 / f12)|=2.59. It can be understood that by limiting |fs×(1 / f123s-1 / f12)| to be equal to 2.59, the focusing of the optical lens 10 can be accurately controlled, thereby improving the focusing effect of the optical lens 10.

[0549] Wherein, 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:

[0550] 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.

[0551] Wherein, 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, thereby being conducive to realizing the shooting of the optical lens 10 on the shooting object in the macro state.

[0552] The magnification ratio Reds of the super-telephoto end of the optical lens 10 in the close-up state satisfies: Reds=0.04. It can be understood that by limiting the magnification ratio Reds of the super-telephoto end of the optical lens 10 in the close-up state to be 0.04, the magnification ratio Reds of the super-telephoto end of the optical lens 10 in the close-up state is larger, which is beneficial to realize the shooting of the shooting object in the close-up state by the optical lens 10.

[0553] The magnification ratio Redss of the super-telephoto end of the optical lens 10 in the macro state satisfies: Redss=0.18. It can be understood that by limiting the magnification ratio Redss of the super-telephoto end of the optical lens 10 in the macro state to be 0.18, the magnification ratio Redss of the super-telephoto end of the optical lens 10 in the macro state is more appropriate, and the optical lens 10 can realize the shooting with a larger magnification ratio on a relatively far shooting object.

It can be understood that by limiting the material refractive index Nd of each lens of the optical lens 10 to be in the range of 1.44 to 2.09 and limiting the Abbe number Vd of each lens of the optical lens 10 to be in the range of 17.13 to 84.4, 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 lens of each lens of the optical lens 10 is higher. In this way, the light transmittance of the lens 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 shot by the optical lens 10 is clearer.

[0555] The focal length f2 of the second lens group G2 and the focal length fs of the super-telephoto end of the optical lens 10 satisfy: f2 / fs=-0.42. It can be understood that by limiting the ratio of the focal length f2 of the second lens group G2 and the focal length fs of the super-telephoto end of the optical lens 10 to be -0.42, the assembly tolerance between the first lens group G1 and the fourth lens group G4 is increased, and the loss of the resolving power of the optical lens 10 is reduced.

[0556] 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 and the focal length f2 of the second lens group G2 to be -5.06, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 are reasonably distributed. Under this focal power distribution, by reasonably setting the refractive index, Abbe number, shape, thickness, air gap of the lens in each lens group, a good balance between the aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be realized.

[0557] wherein the distance AG3 of the third lens group G3 moving along the optical axis in the second direction, the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction, and the focal length fs of the tele end of the optical lens 10 satisfy: |(AG3+AG4) / fs|=0.36. It can be understood that by limiting |(AG3+AG4) / fs| to be equal to 0.36, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction and the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, which is conducive to the miniaturization of the optical lens 10.

[0613] |ft×(1 / f123t-1 / f12)|=1.922. It can be understood that by limiting |ft×(1 / f123t-1 / f12)| to be equal to 1.922, the focusing of the optical lens 10 can be accurately controlled, and the focusing effect of the optical lens 10 is improved.

[0614] fs, the focal length of the first lens group G1, the focal length of the second lens group G2, 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:

[0615] |fs×(1 / f123s-1 / f12)|=3.18. It can be understood that by limiting |fs×(1 / f123s-1 / f12)| to be equal to 3.18, the focusing of the optical lens 10 can be accurately controlled, and the focusing effect of the optical lens 10 is improved.

It can be understood that by limiting the magnification Redt of the long focal end of the optical lens 10 in the macro state to be equal to 0.20, the magnification Redt of the long focal end of the optical lens 10 in the macro state is larger, thereby facilitating the shooting of the optical lens 10 on the shooting object in the macro state.

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 be equal 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 shooting of the optical lens 10 on the shooting object in the close-up state.

It can be understood that by limiting the material refractive index Nd of each lens of the optical lens 10 to be in the range of 1.50 to 1.80, and limiting the Abbe number Vd of each lens of the optical lens 10 to be in the range of 20.35 to 81.56, the refractive index of each lens of the optical lens 10 is smaller, the Abbe number is larger, and the transmittance of the lens of each lens of the optical lens 10 is higher. In this way, the light transmittance of the lens of each lens of the optical lens 10 is stronger, and the optical quality of each lens of the optical lens 10 is higher, so that the image captured by the optical lens 10 is clearer.

[0622] The focal length f2 of the second lens group G2 and the focal length fs of the super-telephoto end of the optical lens 10 satisfy: f2 / fs = -0.38. It can be understood that by limiting the ratio of the focal length f2 of the second lens group G2 and the focal length fs of the super-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 resolving power of the optical lens 10 is reduced.

It can be understood that by limiting the ratio of the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 to be equal to -2.80, the focal length f1 of the first lens group G1 and the focal length f2 of the second lens group G2 are reasonably distributed. Under this distribution of focal power, by reasonably setting the refractive index, Abbe number, shape, thickness, air gap of the lenses in each lens group, a good balance between aberration, volume, cost, thermal reliability, etc. can be achieved, and a wide range of continuous zoom ratios can be achieved.

[0624] Wherein, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction, the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction, and the focal length fs of the telephoto end of the optical lens 10 satisfy: |(AG3+AG4) / fs|=0.342. It can be understood that by limiting |(AG3+AG4) / fs| to be equal to 0.342, the distance AG3 of the third lens group G3 moving along the optical axis in the second direction and the distance AG4 of the fourth lens group G4 moving along the optical axis in the second direction are reduced, or the focal length of the corresponding optical lens 10 is increased, which is beneficial to realize the miniaturization of the optical lens 10.
