[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 Ck'aHe22'  
6F|j(LB  
基本條件是 h<x4YB5Mj  
nidr\oFUIn  
主鏡必須是拋物面 |+}G|hx@9  
73F5d/n  
副鏡必須是球面 m3.sVI0I  
)uheV,ZnY  
系統包含一組校正鏡 A''pS  
3EK9,:<Cf  
口徑200mm以上 d~9!,6X
M  
(zcLx;N  
焦比不限制 \Qy$I-Du  
n<7q`tM#  
視角0.5度以上 \6!W05[ Q  
V 9;[M;  
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. #,NvO!j<4
