温度对长焦距衍/折光学系统消二级光谱设计的影响

Effect on Temperature for Design on Optical System for Secondary Spectrum by Hybrid Diffractive-Refractive

采用光学设计的基本原理,研究了温度对宽光谱、长焦距衍/折混合光学系统消二级光谱设计的影响,研究了本系统使用的玻璃和衍射元件的综合温度特性,提出了合理解决温度对系统影响的方法,使二级光谱保持在设计水平,满足实际使用要求.

By means of principle of optical design,the affect is studied on temperature for optical system of wide spectrum,long foeus. By hybrid diffractive-refractive optics,the properties of temperature of DOL is studied. Reasonable method for solving the effect of temperature is given, and got the result of an accepted secondary spectrum in the system. Secondary spectrum does not affect the quality of sight field the in corrected optical system. The correction method is simple and satisfiable.
