【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。更多还原

【Abstract】 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.更多还原
