摘要
针对长波制冷式384×288焦平面探测器,设计了一款大变倍比长波红外连续变焦距光学系统。整个系统由8片透镜及两个反射镜构成,工作波长范围为7.7～9.3 m,F数为3,满足100%冷光阑效率,变倍比为25:1。采用CODE V光学设计软件进行优化设计,设计结果表明,该系统具有结构简单、变倍比大、体积小、像质好等优点。
An LWIR continuous zooming system based on long-wave cooled 384 -288 focal plane array （FPA） detector with large zooming range is described in this paper.. The system consists of eight lenses and two reflectors, the operating wavelength is 7.7-9.3 um, F number is 3, and the zoom ratio is 25：1, which satisfies 100% cold shield efficiency. The system is optimized by using the CODE V Optical design software. The design results proved that the system has the advantages of simple structure, large zooming ratio, small size and excellent image quality.
