[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 R-v99e iN  
WU}?8\?U%  
基本條件是 EH;w <LvT  
CuE>=y-"I  
主鏡必須是拋物面 _J<^'w^;%  

o)NQE?  
副鏡必須是球面 A]VcQ_e  
m@K5eh  
系統包含一組校正鏡 {~=Edf  
p h[ ^ve  
口徑200mm以上 G]q1_q4P1?  
kYxb@Zn=|  
焦比不限制 qPgLSZv  
 T~I5W=y  
視角0.5度以上 {Vz.| a[T  
K]mR9$/  
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. ^X

經過不斷的努力,做了一些改進. Hl"rGA>
