摘　　要：利用二元光学元件独特的色差特性,将其引入到微光夜视物镜中,得到视场为12.2°、相对孔径为1.507、焦距为84.375mm、长度为88mm、而重量仅为83.5g的光学系统。针对衍射元件衍射效率对系统像质的影响,对系统的传递函数进行了修正。相对于传统光学系统,该系统不仅成像质量高,而且尤为轻便,非常适合军用步枪瞄准器等对重量要求苛刻的小型微光夜视仪的使用。By using the characteristics of diffractive optical element, a hybrid refractive-diffractive optical objective lens for night vision system was designed. The field of view is 12.2°; relative aperture is 1.507; focal length is 84.375; total length is 88mm; weight is 83.5g. The image quality is corrected based on the diffractive efficiency. Compared with traditional optical system without binary optical element, this system not only has high image quality, but also has minimum weight. So it is very suited to use it in aiming device of serve rifle.
