[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 Cc`-34/%  
/YJBRU2  
基本條件是 DrAIQ7Jd  
"-MB 
U  
主鏡必須是拋物面 4oryTckS  

ePv`R'#  
副鏡必須是球面 T\6,@7  
1
{d;Ngx  
系統包含一組校正鏡 N=T}  
5[)#
3vY  
口徑200mm以上 wTZ(vX*mK  
\ISg6v{/  
焦比不限制 dV'^K%#  
;qbK[3.  
視角0.5度以上 t:P]bp^#  
EL z5P}L6  
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. #Hu##x|

經過不斷的努力,做了一些改進. 6oZHSjC*
