摘要
为满足现代智能化设备和红外交互识别的需求,利用CodeV和Zemax光学设计软件设计了一款小型化红外广角镜头。该镜头使用3片塑胶非球面镜片和1片红外带通滤光片,其光学结构形式为负-正-正的结构;该镜头的F数为2.2,全视场最大角度为129°,系统机械总长3.8 mm。该设计在1/2奈奎斯特频率处各个视场的调制传递函数值均大于0.5。组装该镜头进行测试,其调制传递函数性能符合设计需求,可以较好地实现红外探测功能。
Abstract
In order to meet the requirements of modern intelligent equipment and infrared interactive identification, we design a miniature infrared wide-angle lens by CodeV and Zemax optical design software. The lens is equipped with three plastic lenses and one infrared band pass filter. Its optical structure is negative-positive-positive. The design results show that F number is 2.2, the maximum viewing angle is 129° and the mechanical total length is 3.8 mm. Modulation transfer function (MTF) value of all fields is larger than 0.5 at 1/2 Nyquist frequency. The assembled lens is tested to show that MTF performance meets design requirements and the infrared detection function can be achieved.
