Finally, we mention the catadioptric system of schupmann's medial . 最后，我们谈谈舒曼的medial反折射系统。
2.
Mirror is used instead . catadioptric telescopes use both a lens , called correcting plate , and a mirror 顾名思义，折反射式则在入口处有一块称为修正镜的透镜及在底部有一块凹镜。
3.
High resolusion optical systems including refractors , catadioptric lens and reflectors used to observation from the satellites to the earth is presented and the problems in design is discussed 摘要对用于卫星对地观测用各种高分辨率长焦距光学系统，如折射系统，折反射系统和反射系统等各种形式和设计问题进行了分析和讨论。
