[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 BS|-E6E<  
Iwn@%?7  
基本條件是 QX]tD4OH  
m#;:%.Rm  
主鏡必須是拋物面 nf G:4k,  
s_*eX N  
副鏡必須是球面 !J6s^um  
n'h )(^  
系統包含一組校正鏡 'FUPv61()  
[X~X?By>  
口徑200mm以上  +NXj/  
y=j[v},4  
焦比不限制 9vj:=,TNu  
*r%mqAx(  
視角0.5度以上 _fyw  
Z?Q2ed*j  
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. u('OHPqq

經過不斷的努力,做了一些改進. N6[^62
