Abstract

In order to meet the requirement of high image quality and super-wide-angle mobile phone lens, a super-wide-angle mobile phone lens with a curved image surface and 10 megapixels based on monocentric lenses is designed in the paper. The mobile phone lens is composed of 4 monocentric lenses. The focal length is 3.32mm, the F-number is 1.85, the FOV is 95° and the total length is 5.24mm. The final design shows that the MTF is larger than 0.52 in the 0.7 field of view and the MTF of the whole FOV is larger than 0.45 at 209 lp/mm. The MTF is larger than 0.3 in the 0.7 field of view and the MTF of the whole FOV is larger than 0.2 at 417 lp/mm. The RMS radiuses of different fields of view are less than 3 μm . The relative illumination values are greater than 0.6 in the full field of view. The optical system has good image quality.
