摘要:
采用光学被动式无热化设计方法,给出了针对长波红外制冷型光学系统的一个设计实例。该系统采用了576元线列探测器,相比于以往288元线列探测器而言,在相对孔径、焦距等参数不变的条件下,视场扩大了一倍。该系统F数为1.6,焦距100 mm,视场9.2?,实现了100%的冷光阑匹配。设计结果表明,该系统在-50℃~+90℃的宽温度范围内,像质接近衍射限,无须任何调焦,无热化性能良好。
Abstract:
Based on athermal design technologies of optical passive mode, this paper describes an example of a cooled long wave infrared optical system. This system adopts a linear IRFPA with 576 pixels. Compared with old linear IRFPA with 288 pixels, the larger pixel number results in a larger field of view with same parameters such as numerical aperture, focal length, etc. The F number is 1.6, the focal length is 100mm, and the FOV is 9.2?. This system has a 100% cold-shield-match. The result shows that the image quality of the system approaches the diffraction limit in the working temperature range -50℃~+90℃ without focusing mechanism. So its athermal capability is improved
