如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： w4RP*Da?:
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord (O /hu3
_EjS(.e/=
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: tdZ: w
|F9/7 z\5+
(1) 使用 Zygo 干涉儀 P0}uTee
函數 @VFA(zoom #, surface #, height) PM o>J|^
Surface is testable for @VFA < 1.0 DV{Qbe#I n
Surface is not testable for @VFA > 1.0 7QQ1oPV
> *vI:MG8
(2)使用 QED 干涉儀 9QWS[E 4
函數 @SSIa(surface #, zoom #, height) X(g<rz1J]
0 <= @SSIa < 0.5 - surface is readily testable 5x4(5c5^
0.5 <= @SSIa < 1 - surface is marginally testable b3y@!_'c
@SSIa >= 1 - surface is difficult to test
