摘　　要：介绍了大口径长焦距离轴二镜平行光管的设计过程,给出了系统初始结构的求解方程,并分析了主次镜同轴设计方法的缺陷.为提高系统像质,提出了在主次镜同轴方法的基础上对次镜绕主镜焦点旋转的离轴化方法.以一个离轴二镜平行光管作为设计实例,计算了次镜离轴对系统像质的影响,通过次镜的离轴优化,得到了成像质量良好的光学系统设计结果.Design process of large pupil, long focus off-axis two-mirror collimator was introduced. The equation of system initialization structure was given. And the disadvantage of coaxal design method was analysised. A design method for off-axis secondary mirror was proposed. When secondary mirror were rotate on main mirror focus, system performance could be improved. The off-axis design method of secondary mirror was proved throught a example.
