[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 TQH#sx  
7L"/4w  
基本條件是 h='=uj8o5  
3\7$)p+c  
主鏡必須是拋物面 yL-L2  
a/fYD2uNo  
副鏡必須是球面 iI7~9SCE  
VCO/s9AL  
系統包含一組校正鏡 A\Gw+l<h,  
N5DS-g
v  
口徑200mm以上 NBX/V^  
<ZEA&:p  
焦比不限制 2hP8ZfvIR  
d\M !o
*U  
視角0.5度以上 t,_[nu(~8%  
79_MP  
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. sP%.o7&n

經過不斷的努力,做了一些改進. ]n+:lsiV
