| 摘 要： | 介绍一种采用塑料光学元件和玻璃光学元件进行混合设计的微光夜视物镜，该系统利用光学被动无热化原理进行环境适应性设计和像差平衡，其工作波长范围为0.65～0.95 μm，视场为40°，F数为1.2. 利用CODE V光学设计软件对微光夜视光学系统的调制传递函数（MTF）、温度适应性、零件质量等性能进行了综合分析与评价。设计结果表明，在高低温情况下，各个视场的MTF值均大于0.4，光学零件质量为20 g，在实现系统减轻的同时获得了良好的光学性能。

| Abstract: | The design of objective lens for low-light night vision system with plastic and glass optical elements is introduced. The optical athermalization method is used for temperature change and aberration balancing. The operating wavelength is in the range from 0.65 μm to 0.95 μm, the field of view is 40°, and F-number is 1.2. The modulation transfer function (MTF), temperature adaptability and weight of night vision optical system are analyzed and evaluated by the CODE V optical design software. The design result indicates that MTF of all FOVs is more than 0.4 at 40 lines per millimeter in the total temperature range and the weight of all lenses is less than 20 g. The optical system obtains weight reduction and better image quality. |
