[讨论]一個雙反系統的改進 [复制链接]

這是我最近在想的一個設計 hkoCbR0}8  
?h7(,39^>  
基本條件是 >uVr;,=y  
7^*[XH  
主鏡必須是拋物面 XfYhLE  
w//L2.  
副鏡必須是球面 /G& %T  
^Uq"hT(41  
系統包含一組校正鏡 GEQ3r'B|  
L0dj 76'M  
口徑200mm以上 I'>r  
9~6)u=4sS"  
焦比不限制  b@m\ca  
1GI/gc\  
視角0.5度以上 p7eRAQ\'  
U3 y-cgE  
以下是我的結果,目前覺得副鏡的口徑太大,不知道有無改進的可能. z-;2)RkV2

經過不斷的努力,做了一些改進. F\G-. 1
