各位你們好!
想請教 "磨鏡班Notes" 內的 "第八章 主鏡的磨製 : 拋物線化" 中:
"拋物鏡面修正值表" 及 "容許誤差修正值表 ( 吋 )" 之 "球面誤差 (波長)" 欄是如何算出?

豆豸苗,你好!
你是往屆學員,是否有些少頭緒?

I am looking up my "old' notes.
I remeber it is quite complicated and involves several mathmatical formula for calculating the "容許誤差修正值".
Be patient.

From chapter 8,
You can use the "計算球面誤差公式" to calculate "球面誤差".
d is the difference between the spherical and parabolic
surface.
where lamder (波長是 0.000022 吋)
Divide the d (the difference) by the length of one wavelength
(0.000022)
Then you will get how many wavelength from if the mirror is not turned into a parabolic surface.
