[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 2O}s*C$Xav  
6z1aG9G  
基本條件是 XfD z #  
u>JqFw1  
主鏡必須是拋物面 m$j n5:  
^yzo!`)fso  
副鏡必須是球面 =d:R/Z%,  
;9 =}_h)]  
系統包含一組校正鏡 tf.q~@Pi  
~gSF@tz@  
口徑200mm以上 n0Qh9*h  
_|Y.!ZRYP  
焦比不限制 MR^umLM88  
yffU% )  
視角0.5度以上 '8]
|E  

i{%z  
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. XHwZ+=v
