摘要
利用光学软件zemax优化并设计了折返式卡塞格林望远镜系统.新型卡塞格林系统主次镜采用球面反射镜,避免了使用加工困难和成本较高的非球面镜.给出了利用zemax优化设计的整个过程,并通过评价函数、点列图、光线扇面图以及光学传递函数的评价手段对设计的系统进行评价和再优化,最终得到最好成像质量的望远镜系统.
An optical software zemax was used to design a new Cassegrain telescope system in this paper. The primary and secondary mirrors of this system are spherical and the spherical mirror is easily processed. so, it can avoid difficulties in making a spherical mirror and lower the cost. Using default merit function which Zemax automatically creates, zemax can optimize the structure of system automatically. Then by analyzing the charts such as Spot Diagram, Ray Fan, OPD and MTF, the feasibility of the system was evaluated.
