摘要

摘要: 设计了用于非制冷红外焦平面阵列探测器的大视场、大相对孔径的长波红外物镜。系统由3片非球面锗镜组成，采用反远距结构，系统焦距为6mm，相对孔径为1∶0.8，全视场角为160，总长为86.13mm。设计结果表明：在空间频率为20lp/mm处的MTF值大于0.7，接近衍射极限。该系统除具有反远距结构的结构简单、体积小、质量轻、像面照度均匀等优点外，还具有超大视场。

Abstract: A low F number long-wavelength infrared optical system with wide field of view is designed. It consists of three aspherical germanium lenses with a reversed telephoto telecentric structure. The effective focal length is 6mm, the relative aperture is 1:0.8, the full field of view is 160, and the total optical length is 86.13mm. The result shows that the modulation transformation function is greater than 0.7 at the spatial frequency of 20lp/mm. The system inherits the advantages of the reversed telephoto telecentric structure, it is simple in structure and small in volume, light in weight, uniform in illumination, and also has large field of view.
