摘要
红外带通滤光片已成功地应用于我国自行研制的近三十颗卫星的地球敏感器上。本文详细介绍了用等效折射率概念、设计１４～１６．２５μｍ红外带通滤光片的原理和方法，给出了设计的膜系，分析了主要工艺及膜层厚度的控制对红外带通滤光片光学特性的相互影响，并与国内外同类滤光片的光学特性进行了比较。
Infrared bandpass filters have been successfully used in earth sensors of about 30 satellites developed by our country. This paper presents in detail the design principle and method of 14～16.25μm infrared bandpass filter using concept of equivalent refraction index. The film system design is given out and effects of main process technology and film layer thickness control on optical characterics of the filter are analyzed. Finally, optical characteristics of similar filters at home and abroad are compared.
