Abstract

This paper presents an automatic optimization method in ZEMAX sequential mode. The user-defined evaluation function and optimization program are written in macro language, which is used to design the Offner null compensation optical path system. The system is designed with a 1m aperture parabolic lens as an example, of two-piece Offner compensation mirror and the optimal parameters of Offner compensator are obtained through optimization. The compensation residual PV value is better than λ/10 and the RMS value is better thanλ/50. This method is a promising attempt of automatic design of compensator, which can design multiple groups of structures on the basis of improving design efficiency, and make the optimal structure which is more closer to actual demand.
