大相对孔径制冷型红外相机镜头的光学设计
Design of Low F-Number Lens for Cooled Infrared Camera
摘要
介绍了一种大相对孔径红外成像镜头的设计.该镜头针对制冷型红外探测器,采用二次成像设计,保证 100%冷光阑效率.在 8～10 .m波段,实现相对孔径( F数)为 1.5、视场角 2.为 18.6.的设计,其成像质量优良,传函接近衍射极限,在常规加工装调公差下易于保证应用质量.
Abstract
A low F number lens for infrared camera is introduced.Re-imaging method is used to ensure 100% cold shield efficiency in this lens for cooled IR camera.The lens is designed with F number 1.5 and full field angle 18.6.in 8-10 .m waveband.Its imaging quality is nearly up to diffraction limitation and can be guaranteed with general manufacture and assembly technics.
