双透镜无光焦度校正板和单一反射镜的研究(英文)

Study of an optical System with a Two-Lens Null Corrector and a Single Reflector

对双透镜无光焦度校正板和单一反射镜组成的光学系统进行了研究 ,利用三级像差理论分析了消像差条件 ,并得出了一组被证明是正确的公式 根据该公式可以求出光学系统的初始结构参量 对于在球面镜反射系统中 ,基于像差特性分析 。

The aberration characteristics and the con ditions of the absence of various aberrations of the optical system of a two-lens null corrector and a single reflector are studied.A set of formulae are derived based on third-order aberration theory which are proved correct to be used in designing the initial structure of the optical system.The best choice for the structure and the single lens′ optical power of the corrector in a spherical reflector system is also investigated.
