摘要
以微光夜视技术重点实验室研制的AlGaN光阴极日盲紫外像增强器为基础,设计了一款匹配于日盲紫外像增强器的紫外光学系统,以提升探测器的探测性能。光学系统的工作波段在240~280 nm,视场角40°,相对孔径为1/2.5。系统由5块标准球面镜组成,光学系统总长50.74mm;光学传递函数在空间频率为401p/mm时,轴上不小于0.8,轴外不小于0.6;成像质量良好,结构紧凑,满足设计要求。
Based on the AlGaN photocathode solar-blind UV image intensifier developed by the Science and Technology on Low-Light-Level Night Vision Laboratory,this study designs a UV optical system that matches the solar-blind UV image intensifier to improve the detection performance of the detector.The working wavelength of the optical system is 240-280 nm,the field of view is 40°,and the relative aperture is 1/2.5.The system consists of five lenses that are all spherical mirrors,and the total length of the optical system is 50.74mm.When the optical transfer function is 40 lp/mm,the on-and off-axes are greater than or equal to 0.8 and 0.6,respectively.The imaging quality is good,and the structure is compact to meet the design requirements.
