如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: jNy.Y8E&
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord ?R#)1{(8d~
as_PoCoss
如果想知道的是某一非球面的型狀是否能由干涉儀測量,那麼 Code V 提供兩個函數: E+JqWR5
{qMIGwu
(1) 使用 Zygo 干涉儀 1!gbTeVlY
函數 @VFA(zoom #, surface #, height) z$xo$R(
Surface is testable for @VFA < 1.0 PiYxk+N
Surface is not testable for @VFA > 1.0 ofv)SCjd
= 9]~yt
(2)使用 QED 干涉儀 BVO<e \>3
函數 @SSIa(surface #, zoom #, height) Tu 7QCr5*
0 <= @SSIa < 0.5 - surface is readily testable 09Cez\0
0.5 <= @SSIa < 1 - surface is marginally testable O1mKe%'|
@SSIa >= 1 - surface is difficult to test
