基于ZEMAX的折反射式望远物镜的设计

Design of a catadioptric telescope objective based on ZEMAX

折反射式望远物镜顾名思义是将折射系统与反射系统相结合的一种光学系统,这种系统的特点是便于校正轴外像差.以球面镜为基础,加入适当的折射元件,用以校正球差,得以取得良好的光学质量.在设计过程中通过对计算数据的优化、对像差的校正,逐步达到了预期的要求.这次设计的折反射式望远物镜由两片球面反射镜及五片折射透镜组成.

Catadioptric telescope objective by definition is the refraction and reflection system combining an optical system. The characteristic of this system is to facilitate the correction of axis aberrations. Spherical mirror, adding the appropriate refractive components for the cor- rection of spherical aberration, can achieve good optical quality. In the design process, through the optimization for datas and the correction for aberration the expected require- ments are reached gradually. The design of this catadioptric telescope objective consists two pieces of spherical mirrors and five refractive lens.
