    摘要
  • 摘要: 针对冷光栏Ｆ数为１．２７的４８０６元长波制冷型红外探测器，设计了焦距３２５ ｍｍ、Ｆ数达１．３５、视场为１．０５的用于红外警戒或搜索系统的６ 片式光学系统，该系统光学透过率为７６％，冷屏效率１００％。

     

    Abstract: A 6-piece lens used for infrared warning or searching system was designed, based on the 4806 long wavelength infrared(LWIR) detector with the F number of 1.27. The designed lens has 325mm focal length, 1.35 F number and 1.05FOV .The transmittance is 76% and the cold shield efficiency is 100%.
