[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 Fu#mMn0c  
ZG)%vB2c  
基本條件是 Y,C3E>}Dq  
+"2IQme5  
主鏡必須是拋物面 9WsGoZPn  
EX^j^#N  
副鏡必須是球面 TZ%u;tBH:  
iKuSk~  
系統包含一組校正鏡 bcZ s+FOPd  
BF>3CW7  
口徑200mm以上 ^H UNq[sQ  
B*j AD2  
焦比不限制 l*C(FPw4  
m>@ *-*8k  
視角0.5度以上 (E(k
w="  
gsp|?)]x  
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. w6[uM%fHG
