[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 .KKecdd?=  
g;=VuQuP|  
基本條件是 [ne51F5_  
FWJ**J  
主鏡必須是拋物面 !.,J;Qt  
Ik^^8@z  
副鏡必須是球面 .Pj<Pe  
[hSJ)IZh  
系統包含一組校正鏡 h#Z["BG  
aC`>~uX##V  
口徑200mm以上 VIdKe&,  
i[9yu-  
焦比不限制 jUM'f24  
;>mM9^Jaf
 
視角0.5度以上 l#enbQ`-~  
H2%Qu<Kg2  
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. Hg

經過不斷的努力,做了一些改進. dPu
