Optical Design Of Small Imaging Lens With Large Field Of View Angle

In order to meet the application requirement of low cost micro camera with large field of view, a small imaging lens with large field of view angle was designed, and the double Gauss structure was selected as the initial structure of the system. Use ZEMAX to perform a default evaluation function and manual image quality optimization for the system. The aberration of the system is reduced by adding the high order aspherical surface. Finally, the optical system that meets the requirements is obtained. The system has good image quality with 80lp/mm frequency larger than 0.3.
