[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 |h}/#qhR  
L?:.8k`d  
基本條件是 >|Yr14?7  
&m<:&h& b  
主鏡必須是拋物面 !6.}{6b  
pbc<326X"  
副鏡必須是球面 lrrNyaFn  
nsW#  
系統包含一組校正鏡 moz*=a  
}h{
8i_R  
口徑200mm以上 >8%<ML  
7-S?\:J  
焦比不限制 jMFLd  
L{PH8Xl_  
視角0.5度以上 <Cv6wC=  
W@S>#3,  
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^Dklqqy

經過不斷的努力,做了一些改進. w,)O*1't
