[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 6^VPRp  
!4vepa}Y  
基本條件是 UNF@%O4_T  
MJugno  
主鏡必須是拋物面 WvN{f*  
zXZXp~7)  
副鏡必須是球面 }l<:^lX  
9NC?J@&B  
系統包含一組校正鏡 (,I9|  
8Xx4W^*_  
口徑200mm以上 `_+%  
E@/*
eJ  
焦比不限制 KbGz3O'u  
OVUJiBp  
視角0.5度以上 ;km^ OO$  
h1Nd1h@-  
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. :um]a70

經過不斷的努力,做了一些改進. _&N}.y)+t
