波差法设计长焦距复消色平行光管物镜

Long Focus Collimator Lens Design of The Three Color Achromats With Wave Disparity Method

长焦距复消色平行光管物镜是光学设计的两大难题之一，本文利用波差与球差、慧差、波色差与位置色差、二级光谱的关系导出了求解三胶合复消色差平行光管物镜初始结构的方程式，再配以玻璃库，可较快地得到满意的复消色差物镜的结构参数．

ong focus collimator lens design of the three color achromats is one of the two key problems of optical design. In this paper, by use of the relationships between wave disparity,spherical abberation and coma, and wavefront chrolnatic abberation,chromatic dfference of focal length and secondary spectrum,the equations of solving original structure for the three color achromatic triplet are deduced. Providing glass library in the compute,the satisfied structural parameters of the three color achromats are acquired quickly.
