为设计一套基于球面的600mm口径望远镜系统, 分析了四种可能的实现形式, 即Maksutov, Houghton, Klevtsov和使用Cook补偿镜的Cassegrain形式, 并分别得到了满足指标要求的设计结果。通过分析每种形式的优缺点, 结果表明, 使用Cook补偿镜的Cassegrain形式最为适合, 并对其进行了详细的分析和设计。

To design a telescope system based on spheric component, four different possible forms are analyzed, they are Maksutov, Houghton, Klevtsov and Cassegrain with Cook correctors, and the designing results to satisfy the demands are given respectively. Through analyzing the advantages and defects of each form, the result shows that Cassegrain with Cook correctors is most appropriate.
