| 摘 要： | 分析了空间双波段成像光谱仪光学系统的光学特性，提出利用光学材料间焦距位移系数的互补性，实现光学系统消热差、消色差设计方法，建立了一组既消热差又消色差的方程组. 给出了利用这种方法设计的视场角10°，焦距100 mm，F数为1.98，温度范围在－20℃~70℃，工作波长为3~5 μm和8~11 μm具有100％冷光栏效应的双波段消热差、消色差光学系统，分析了系统各波段传递函数、波前差及像面位移随温度变化关系. |

| Abstract: | Optical features of optical system of a dual-band imaging spectrometer is analyzed.Based on the mutual compensation of optical materials focal plane shift constant, the equations are formulated for athermalization of optical system. A design example of a three lenses optical system with two materials operating in the 3～5 μm and 8～11 μm wavelength bands with 100% cold shield efficiency, 10° field of view, 100 mm focal length, 1.98 F number is designed, associated with high optical quality in large working temperature range -20～70°C. The defocus, wavefront error and modulation transfer function(MTF) of optical system are analyzed. |
