[0045] In an exemplary embodiment, the third lens having negative optical power and a concave image side surface is combined with the fourth lens having positive optical power and a convexoconcave surface, which is beneficial for reducing the spherical aberration and astigmatism of the camera lens group.

[0046] In an exemplary embodiment, the fifth lens having a convex-concave surface is matched with the sixth lens having a positive optical power and a concave-convex surface, which is beneficial for making the camera lens group have characteristics such as a compact structure, a large aperture and good imaging quality; and is also beneficial for the processing of the camera lens group.

More specifically, f6 and f may further satisfy: 2.10<f6 / f<3.60. By satisfying 2.00<f6 / f<4.00, the focal length of the sixth lens may be controlled within a reasonable range, so that it can bear the positive focal length required by the camera lens group, and the spherical aberration it contributes may be controlled within a reasonable range, ensuring that the subsequent optical lens can reasonably correct the spherical aberration it contributes, so that the on-axis field of view of the camera lens group has better image quality.

More specifically, CT7 and T67 may further satisfy: 8.80<CT7 / T67<14.90. Satisfying 8.00<CT7 / T67<15.00 can effectively constrain the thickness of the seventh lens and the spacing between the sixth lens and the seventh lens, so that the lens thickness is uniform, the structure is uniformly arranged, and molding and assembly are facilitated.

[0054] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 1.00<SAG101 / SAG102<7.00, wherein SAG101 is the distance from the intersection of the object side surface of the tenth lens and the optical axis to the effective radius vertex of the object side surface of the tenth lens on the optical axis, and SAG102 is the distance from the intersection of the image side surface of the tenth lens and the optical axis to the effective radius vertex of the image side surface of the tenth lens on the optical axis. More specifically, SAG101 and SAG102 may further satisfy: 1.70<SAG101 / SAG102<6.50. Satisfying 1.00<SAG101 / SAG102<7.00 can effectively control the aperture size and shape of the tenth lens, which is conducive to achieving a large image plane characteristic, so that the off-axis field of view can obtain a higher light transmittance, and at the same time is conducive to reducing stray light.

[0055] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 2.00<(SAG71+SAG72) / (SAG72-SAG71)<6.00, wherein SAG71 is the distance from the intersection of the object side surface of the seventh lens and the optical axis to the effective radius vertex of the object side surface of the seventh lens on the optical axis, and SAG72 is the distance from the intersection of the image side surface of the seventh lens and the optical axis to the effective radius vertex of the image side surface of the seventh lens on the optical axis. More specifically, SAG71 and SAG72 may further satisfy: 2.60<(SAG71+SAG72) / (SAG72-SAG71)<5.60. Satisfying 2.00<(SAG71+SAG72) / (SAG72-SAG71)<6.00 can effectively constrain the shape and thickness of the seventh lens, making the lens thickness uniform and facilitating molding and processing.

[0056] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 2.00<(ET9+ET10) / (ET10-ET9)<7.00, wherein ET9 is the edge thickness of the ninth lens, and ET10 is the edge thickness of the tenth lens. More specifically, ET9 and ET10 may further satisfy: 2.50<(ET9+ET10) / (ET10-ET9)<6.80.

[0057] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 22.00<(DT101+DT102) / (DT102-DT101)<31.00, wherein DT101 is the maximum effective radius of the object side of the tenth lens, and DT102 is the maximum effective radius of the image side of the tenth lens. More specifically, DT101 and DT102 may further satisfy: 22.70<(DT101+DT102) / (DT102-DT101)<30.50. Satisfying 22.00<(DT101+DT102) / (DT102-DT101)<31.00 can effectively constrain the aperture of the tenth lens, which is beneficial to control the step difference of the assembly of each lens of the camera lens group within a reasonable processing range, facilitate molding processing and assembly, and at the same time be beneficial to obtain a higher light transmittance in the off-axis field of view.

[0058] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 24.00<f56 / BFL<40.00, wherein f56 is the combined focal length of the fifth lens and the sixth lens, and BFL is the distance on the optical axis from the image side surface of the tenth lens to the imaging surface of the camera lens assembly. When 24.00<f56 / BFL<40.00 is satisfied, the coma and distortion contributions of the fifth lens and the sixth lens can be effectively controlled within a reasonable range, so that the image quality of the on-axis field of view and the off-axis field of view will not be significantly degraded due to the contribution of the coma.

[0059] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: TTL / ImgH<1.50, wherein TTL is the distance from the object side of the first lens to the imaging surface of the camera lens assembly on the optical axis, and ImgH is half the diagonal length of the effective pixel area on the imaging surface of the camera lens assembly. Satisfying TTL / ImgH<1.50 can effectively ensure that the camera lens assembly has an ultra-thin characteristic.

[0060] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: Fno≤1.60, where Fno is the F number of the camera lens assembly. Satisfying Fno≤1.60 can effectively ensure that the camera lens assembly has a large aperture characteristic, making the depth of field shallower, which is conducive to highlighting the subject and simplifying the picture.

[0061] In an exemplary embodiment, the camera lens group according to the present application also includes an aperture arranged between the object side and the first lens. Optionally, the above-mentioned camera lens group may also include a filter for correcting color deviation and / or a protective glass for protecting the photosensitive element located on the imaging surface. The present application proposes a camera lens group with characteristics such as ultra-thin, large aperture, large image surface, and high imaging quality. For a camera lens group with large aperture and ultra-thin characteristics, on the premise of meeting the large image surface, the larger the aperture, the greater the amount of light entering, which can effectively increase the shutter speed, and the better the background blur effect. The ten-piece ultra-thin characteristic can also ensure the ultra-thinness of portable electronic products such as smartphones while fully improving the optical performance, and better adapt to the field of view requirements and the market trend of ultra-thin portable electronic products such as smartphones. The camera lens group according to the above-mentioned embodiment of the present application can use multiple lenses, such as the ten lenses mentioned above. By rationally allocating the optical power, surface shape, center thickness of each lens, and axial spacing between lenses, etc., the incident light can be effectively focused, the total optical length of the imaging lens can be reduced, and the machinability of the imaging lens can be improved, making the camera lens group more conducive to production and processing.

[0062] In the embodiment of the present application, at least one of the mirror surfaces of each lens is an aspherical mirror surface, that is, at least one of the mirror surfaces from the object side of the first lens to the image side of the tenth lens is an aspherical mirror surface. The characteristic of the aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, at least one of the object side and image side of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, the ninth lens and the tenth lens is an aspherical mirror surface. Optionally, the object side and image side of each lens in the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, the ninth lens and the tenth lens are all aspherical mirror surfaces.

[0063] However, those skilled in the art should understand that, without departing from the technical solution claimed in the present application, the number of lenses constituting the camera lens group can be changed to obtain the various results and advantages described in this specification. For example, although ten lenses are described as an example in the embodiments, the camera lens group is not limited to including ten lenses. If necessary, the camera lens group may also include other numbers of lenses.
