摘要
针对320×256双色非制冷探测器，设计了双波段／双视场红外光学系统，该系统可以实现焦距为37mm／100mm两档切换，工作波段为3．7-4-3μm/7．7～9．3μm。系统F数为1．2，由5片透镜组成，包含3个非球面。设计结果表明，该系统具有结构简单、透过率高、体积小、像质高等优点。
A Dual-waveband/Dual-FOV uncooled infrared optical system is designed for the 320 ~ 256 FPA dual-waveband uncooling detector. The system can achieve dual field-of-view with the focal length of 37mm/100mm at the spectrum region of 3.7~4.3 lμm/7.7-9.3 μm. The system whose F number is 1.2 consists of 5 lenses with 3 aspheric surfaces. The result of the design shows its advantages of small size, simple structure, high optical transmission and excellent image quality.
