[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 zQH]s?v  
(shK  
基本條件是 oh#> 5cA8  
O4No0xeWo  
主鏡必須是拋物面 15zrrU~D  
M8@_Uj  
副鏡必須是球面 sl/)|~3!8  
NNa1EXZ[  
系統包含一組校正鏡 fj4^VXD  
#^&jW  
口徑200mm以上 137Xl>nO

fJ9HW  
焦比不限制 nSY-?&l6P  
=!ac7i\F  
視角0.5度以上 {$^SP7qV#>  
6U,fz#<,}  
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. s6=YV0w(

波像差真小啊！

經過不斷的努力,做了一些改進. "<*nZ~nE)
