从视场设计出发 ,分析了锗基片的厚度和光学材料吸收特性对光学设计的影响 ,介绍了红外光学系统优化设计的方法 ,给出了设计结果 ,并与国内同类地球模拟器的光学特性进行比较 ,说明准直式地球模拟器光学系统设计是成功的。

In this paper, the effect of germanium su bs trate thickness and infrared optical material absorbance on the optical design a re researched based on the view field design. The optimal design procedures of i nfrared optical system is described. The result of the design is given. And then the optical characteristics of similar earth simulators at home are compared. T hese results show that the optical system of the collimated lens design is succe ssful. <
