Abstract

The structure of the initial system is calculated according to the aberration theory, in which the radius of the primary mirror is 300 mm, the radius of the secondary mirror is 320 mm, the distance between the primary mirror and the secondary mirror is 90 mm, and the blocking ratio is close to 0.4, and the occlusion ratio is close to 0.4. A three-piece correction lens set is designed to solve the spherical aberration and comet aberration caused by the Cassegrain system in the large field of view, and the imaging of the edge field of view of the large field of view system is realized. Through the optimization and layout of the overall system, the MTF value of the system is finally greater than 0.4 within the frequency of 130 lp/mm. This paper provides important reference value for the design of catadioptric optical system with large aperture and large field of view.
