摘要
定性地论述了卡塞格林系统设计中焦距、场镜焦距和后工作距离大小的选择 并论述了在设计中主、次镜必须根据设计结果的分析 ,调整主、次镜的半径和间隔 ,从而使后工作距离 ,遮栏比都能满足设计要求 ,最终使系统能够获得最优的设计性能以满足设计需要 ,在系统的垂轴像差难以消除时 。
The author presents the relationship of focal length of Cassegrain, focal length of field mirror and back focal length from qualitative analysis, and also presents that the primary and secondary mirror must change their radiuses and distances according to the design results so as to make the obscuration and back focal length to meet the damands. The final goal is to make the system to achieve the better image to meet the design demand. When it is difficult to correct the transverse aberration,the position of aperture stop can be changed.
