[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 LoOyqJ,  
7$x@;%xd  
基本條件是 6'(5pt  
+ h`:qB  
主鏡必須是拋物面 [aO"9
 
T=VVK6Lc:  
副鏡必須是球面 ^*A/92!yF  
fTY@{t  
系統包含一組校正鏡 *Zt)J8C  
{ YJ.BWr  
口徑200mm以上 fL83:<RK  
rNU,(htS  
焦比不限制 X_HR$il  
=zVbZ7  
視角0.5度以上 j2qDRI  
?P<&8eY  
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. 8PXleAn

經過不斷的努力,做了一些改進. dr9I+c7
