摘要
离轴三反光学系统具有大口径、大视场、传输效率高以及没有色差等优点,易于实现多谱段共孔径。介绍了一种离轴三反系统的设计,其工作于红外中波3～5μm和红外长波8～10μm双波段,口径300 mm,F数为3。设计中充分考虑加工检测和装调的易实现性,特点为次镜采用球面,主镜和三镜共面,并且整个系统没有高次非球面;选取合理的反射镜和结构件材料,使系统具有良好的高低温环境适应性。
Off-axis three-mirror system has the advantages of large aperture, large field of view, high transmission efficiency and achromaticity, so it＇s easy to achieve co-aperture in wide wave band. An off-axis three-mirror system with 300 mm aperture and F/# 3 is introduced, which works in mid-wave （ 3-5 μm） and long wave （8-10 μm） IR band. It is considered adequately in design that the system will be easy to test and assemble. The system can well adapt wide environment temperature change by choosing right materials.
