Abstract: Based on the requirements of modern society for high pixels and miniaturization of mobile phone lenses, based on the principle of concentric lenses, a concentric reflective mobile phone lens was designed. Through optical path calculation, the spherical aberration expression of the system was solved, and the initial structure of the system was further obtained. The optical system was designed using optical design software, the lens adopted a curved sensor with a pixel size of 1.25 μm, the F number of the optical system was 1.8, the focal length was 2.7 mm, the maximum full field of view was 100°, and the total system length was 2.7 mm. The results show that at the spatial cut-off frequency of 400 lp/mm, the modulation transfer functions of the 0.7 field of view are all greater than 0.34, and the modulation transfer functions of the full field of view are all greater than 0.23. The radius of the diffuse spot in each field of view is smaller than the Airy disk. In the full field of view, the relative illuminance is higher than 0.64. This design meets the imaging requirements of mobile phone lenses.
