摘　　要：给出了可用于超 2代和第 3代Φ18/Φ18倒像式微光像增强器的折反射物镜。物镜相对口径 1.0 /1.2 ,视场± 2 .9°,焦距 180 mm,工作波段 435 .8～ 90 0 .0 nm,重量较常规设计减少约 30 % ,结构紧凑且易于加工和装调。文中介绍了主要设计思想及关键技术问题的处理方法 。A compact and wide spectrum catadioptric low light lens, that is fit for the super second generation or the third generation π18/φ18 inverted image intensifiers are designed. The lens have relative aperture of 1.0/1.2, field of view ±2.9°, effective focal length of 180 mm, and waveband of 435.8-900.0 nm. The lens is lighter than commonly designed lens by 30% and is easy to fabricate and assemble. The main design principles and treatment for the key technical problems are outlined. The aberration plot and modulation transfer function are also given.
