[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 IGT_ 5te  
-/c1qLdQ  
基本條件是 ZHlin#"  
Z(mn U;9{v  
主鏡必須是拋物面 .oj"ru  
KHz838C]  
副鏡必須是球面 g/Jj]X#r  
#0^3Wm`X;  
系統包含一組校正鏡 }#*zjMOz  
a=.db&;vY  
口徑200mm以上 n "KJB  
!a(qqZ|s  
焦比不限制 *9Js:z7I  
S\g7wXH  
視角0.5度以上 X]MM7hMuR  
}|"*"kxi!  
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. S aet";pf`

經過不斷的努力,做了一些改進.
