More specifically, R13 and R14 may further satisfy: |(R13-R14) / (R13+R14)|<0.4.

[0065] In an exemplary embodiment, the optical camera system according to the present application may satisfy: 1<(ET2+ET3) / (CT2+CT3)<1.5, wherein ET2 is the edge thickness of the second lens, ET3 is the edge thickness of the third lens, CT2 is the center thickness of the second lens on the optical axis, and CT3 is the center thickness of the third lens on the optical axis.

More specifically, CT6 and CT7 may further satisfy: 0.9<CT6 / CT7<1.2. Satisfying 0.8<CT6 / CT7<1.2 is conducive to making the central field of view light have a smaller incident angle when reaching the sixth lens and the seventh lens, reducing the MTF tolerance sensitivity of the central field of view.

[0074] In an exemplary embodiment, the optical camera system according to the present application may satisfy: 0.7<SL / TTL<1, wherein SL is the distance from the aperture to the imaging surface of the optical camera system on the optical axis, and TTL is the distance from the object side of the first lens to the imaging surface of the optical camera system on the optical axis. Satisfying: 0.7<SL / TTL<1 is conducive to achieving the ultra-thin feature of the system, and at the same time, the off-axis relative illumination can be controlled within a reasonable range.

[0075] In an exemplary embodiment, the optical camera system according to the present application also includes an aperture arranged between the object side and the fourth lens, for example, an aperture arranged between the object side and the first lens or the third lens and the fourth lens. Optionally, the above-mentioned optical camera system 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 an optical camera system with the characteristics of miniaturization, large image surface, ultra-thinness and high imaging quality. The optical camera system according to the above-mentioned embodiment of the present application may use multiple lenses, such as the nine lenses mentioned above. By reasonably allocating the optical power, surface shape, center thickness of each lens and the on-axis spacing between each lens, 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 optical camera system is more conducive to production and processing.

[0076] 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 ninth 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 occurring 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 and the ninth 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 and the ninth lens are all aspherical mirror surfaces.

[0077] However, it should be understood by those skilled in the art that, without departing from the technical solution claimed in the present application, the number of lenses constituting the optical camera system can be changed to obtain the various results and advantages described in this specification. For example, although nine lenses are described as an example in the embodiment, the optical camera system is not limited to including nine lenses.
