如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： ^36M0h|R
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord 6P0y-%[Gk
^ H'hD
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: Lf5%M|o.)
1Z\(:ab13
(1) 使用 Zygo 干涉儀 p@#]mVJ>9
函數 @VFA(zoom #, surface #, height) 99J+$A1
Surface is testable for @VFA < 1.0 N YCj; ,V
Surface is not testable for @VFA > 1.0 7sj<|g<h(_
aML#Z |n
(2)使用 QED 干涉儀 EYA/CI
函數 @SSIa(surface #, zoom #, height) }16&1@8
0 <= @SSIa < 0.5 - surface is readily testable 5iP8D<;o5
0.5 <= @SSIa < 1 - surface is marginally testable Q }WL/X5
@SSIa >= 1 - surface is difficult to test
