本文基于Schupmann消色差理论，介绍了一种离轴四反射镜衍射成像光学系统设计方法。设计了口径1 m、F数为8、视场0.12°、波段582.8 nm~682.8 nm的离轴四反射镜衍射成像光学系统。设计结果表明，该光学系统的色差得到有效校正，系统调制传递函数(MTF)在50 lp/mm范围内优于0.53，弥散斑半径的均方根值小于艾里斑半径，成像质量接近衍射极限。分析了平面衍射物镜和曲面衍射校正镜可分别采用二元光刻工艺和金刚石车削技术制作的原因。对设计结构进行公差分析，确定公差误差主要来源于中继反射镜的倾斜角度，为装调过程提供指导。设计的系统为宽波段、高像质的反射式衍射成像光学系统发展提供了参考。
