摘要
对近红外波段玻璃材料的相对部分色散进行了研究计算,分析了近红外波段长焦距光学系统的二级光谱特性。并设计了焦距180mm,F#1.2的大视场近红外微光探测物镜,该系统采用ZF、ZK类普通玻璃,且无胶合面,满足露天环境使用。
The partial dispersion of glass working on the near infrared band was caculated, and the apochromatic of a long focal length system was analyzed. A low light near infrared video camera lens was designed, whose focal length is 180mm, F-number is 1.2. Two kinds of glasses, ZF and ZK, was used in this optical system. As a video camera lens, It can be used outdoor environment.
