无光焦度校正板在主镜后的牛顿光学系统的设计

A Newton Optical System with a Zero-power Corrector after Primary Mirror

描述了无光焦度校正板放在主反射镜后的无光焦度校正板-牛顿光学系统的设计.光栏放在主镜上,改变相对孔径A,选择校正板光焦度φ21、φ22和遮拦比α,进行光学系统的光线追迹,求解出光学系统的最佳选择,并给出各种设计曲线和设计结果,对光学系统进行合理的评价.

The design method of a Newton optical system with a zero-power corrector which is after the primary mirror was described. The stop was located in the primary mirror. By moving the stop, changing the relative aperture A,selecting the powers φ11 and φ12 of the corrector and the obstruction ratio α of the system,and calculating the rays of the optical system concerned,the optimized optical system solution was obtain,various design curves and results were given,and the optical system was evaluated.
