[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 4_KRH1  
p5V.O20  
基本條件是 8b|m66#|  
'-2|GX_o  
主鏡必須是拋物面 C'&t@@
:  
'{F Od_uk%  
副鏡必須是球面 }nt,DG!r  
f1wwx|b%.  
系統包含一組校正鏡 V }wh  
@"vTz8oY@  
口徑200mm以上 A4IPd  
R-]i BL  
焦比不限制 52v@zDY  
=|O><O|  
視角0.5度以上 #+SdX[N  
r34 GO1d  
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. ,0^9VWZV
