[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0039] The features, principles and other aspects of the present application are described in detail below.
[0040] The camera lens group according to the exemplary embodiment of the present application may include ten lenses with optical power, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens and a tenth lens. The ten lenses are arranged in sequence from the object side to the image side along the optical axis. Any two adjacent lenses from the first lens to the tenth lens may have a spacing distance between them.
[0041] In an exemplary embodiment, the first lens may have positive optical power, and its object side surface may be convex, and the image side surface may be concave; the second lens may have negative optical power, and its object side surface may be convex, and the image side surface may be concave; the third lens may have negative optical power, and its object side surface may be convex, and the image side surface may be concave; the fourth lens may have positive optical power or negative optical power, and its object side surface may be convex, and the image side surface may be concave; the fifth lens may have positive optical power, and its object side surface may be convex, and the image side surface may be convex; the sixth lens may have negative optical power, and its object side surface may be concave, and the image side surface may be convex; the seventh lens may have positive optical power, and its object side surface may be convex; the eighth lens may have positive optical power, and its object side surface may be concave, and the image side surface may be convex; the ninth lens may have negative optical power, and its image side surface may be concave; the tenth lens may have negative optical power, and its object side surface may be convex, and the image side surface may be concave.
[0042] In an exemplary embodiment, by reasonably setting the optical focal length and surface characteristics of the first lens to the tenth lens, the camera lens group can have a smaller total optical length, and the image plane size of the camera lens group can be increased while facilitating lens processing and manufacturing, thereby improving the resolution.
[0043] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: ImgH≥5.00mm, where ImgH is half of the diagonal length of the effective pixel area on the imaging plane of the camera lens assembly. Satisfying ImgH≥5.00mm is conducive to achieving a large image plane feature.
[0044] 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 not only make the camera lens assembly have a higher resolution while having better processability, but also avoid the camera lens assembly being too long.
[0045] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 4.00 mm < tan 2 (Semi-FOV)×f<5.00mm, where Semi-FOV is half of the maximum field of view of the camera lens group, and f is the total effective focal length of the camera lens group. More specifically, Semi-FOV and f may further satisfy: 4.20mm<tan 2 (Semi-FOV)×f<4.90mm. Satisfy 4.00mm<tan 2 (Semi-FOV)×f<5.00mm, which can not only make the field of view of the camera lens group within the optimal range of 40°-45°, but also achieve higher resolution.
[0046] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 6.00<f2 / f10<10.00, wherein f2 is the effective focal length of the second lens, and f10 is the effective focal length of the tenth lens. More specifically, f2 and f10 may further satisfy: 6.80<f2 / f10<10.00. Satisfying 6.00<f2 / f10<10.00 is conducive to balancing the aberrations of the front lens assembly and the rear lens assembly, thereby improving the image quality of the camera lens assembly.
[0047] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 9.00<R2 / R1<23.00, where R1 is the radius of curvature of the object side surface of the first lens, and R2 is the radius of curvature of the image side surface of the first lens. More specifically, R2 and R1 may further satisfy: 9.80<R2 / R1<22.00. Satisfying 9.00<R2 / R1<23.00 can reduce sensitivity and field curvature.
[0048] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 3.00<f5 / R20<6.00, where f5 is the effective focal length of the fifth lens, and R20 is the radius of curvature of the image side surface of the tenth lens. More specifically, f5 and R20 may further satisfy: 3.80<f5 / R20<6.00. Satisfying 3.00<f5 / R20<6.00 can reduce high-order spherical aberration.
[0049] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 3.00<T56 / T67<8.00, wherein T56 is the spacing distance between the fifth lens and the sixth lens on the optical axis, and T67 is the spacing distance between the sixth lens and the seventh lens on the optical axis. More specifically, T56 and T67 may further satisfy: 3.70<T56 / T67<7.20. Satisfying 3.00<T56 / T67<8.00 helps to reduce the overall size of the lens and save space.
[0050] In an exemplary embodiment, the camera lens group according to the present application may satisfy: 1.00<(SAG61+SAG62) / (SAG61-SAG62)<5.00, wherein SAG61 is the distance from the intersection of the object side surface of the sixth lens and the optical axis to the effective radius vertex of the object side surface of the sixth lens on the optical axis, and SAG62 is the distance from the intersection of the image side surface of the sixth lens and the optical axis to the effective radius vertex of the image side surface of the sixth lens on the optical axis. More specifically, SAG61 and SAG62 may further satisfy: 1.60<(SAG61+SAG62) / (SAG61-SAG62)<4.40. Satisfying 1.00<(SAG61+SAG62) / (SAG61-SAG62)<5.00 can improve both processability and relative illumination.
[0051] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 9.00<(DT101+DT102) / (DT102-DT101)<27.00, 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: 9.80<(DT101+DT102) / (DT102-DT101)<26.50. Satisfying 9.00<(DT101+DT102) / (DT102-DT101)<27.00 helps to reduce the chief ray angle CRA.
[0052] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 3.00<(ET2+ET6) / (ET6-ET2)<8.00, wherein ET2 is the edge thickness of the second lens, and ET6 is the edge thickness of the sixth lens. More specifically, ET2 and ET6 may further satisfy: 3.40<(ET2+ET6) / (ET6-ET2)<7.30. Satisfying 3.00<(ET2+ET6) / (ET6-ET2)<8.00 can both improve the processability of the lens and reduce field curvature and CRA.
[0053] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 8.00<f89 / BFL<14.00, wherein f89 is the combined focal length of the eighth lens and the ninth lens, and BFL is the distance from the image side surface of the tenth lens to the imaging surface of the camera lens assembly on the optical axis. More specifically, f89 and BFL may further satisfy: 8.10<f89 / BFL<13.80. Satisfying 8.00<f89 / BFL<14.00 can achieve both miniaturization of the lens and control of field curvature.
[0054] In an exemplary embodiment, the camera lens assembly according to the present application may satisfy: 3.00<f6 / f910<6.00, wherein f6 is the effective focal length of the sixth lens, and f910 is the combined focal length of the ninth lens and the tenth lens. More specifically, f6 and f910 may further satisfy: 3.50<f6 / f910<5.90. Satisfying 3.00<f6 / f910<6.00 is conducive to controlling the aberration of the camera lens assembly.
[0055] 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 the characteristics of miniaturization, ultra-thinness, large image surface, high imaging quality, etc. The camera lens group according to the above-mentioned embodiment of the present application may use multiple lenses, such as the ten lenses described above. By reasonably allocating the optical focal length, surface shape, center thickness of each lens, and axial spacing between each lens, etc., the incident light can be effectively converged, the total optical length of the imaging lens can be reduced, and the processability of the imaging lens can be improved, so that the camera lens group is more conducive to production and processing.
[0056] 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.
[0057] 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.
