如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： EKwA1,Xz
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord Q $wa<`
Ai99:J2k
如果想知道的是某一非球面的型狀是否能由干涉儀測量，那麼 Code V 提供兩個函數: Zjo8/
aq a%B
(1) 使用 Zygo 干涉儀 .'+*>y!
函數 @VFA(zoom #, surface #, height) D'dE!CAUs
Surface is testable for @VFA < 1.0 WGx e3(d
Surface is not testable for @VFA > 1.0 "Zu hN(-`
fWr6f`de
(2)使用 QED 干涉儀 *""JE'wG
函數 @SSIa(surface #, zoom #, height) *Ey5F/N}$H
0 <= @SSIa < 0.5 - surface is readily testable ]6PX4oK _t
0.5 <= @SSIa < 1 - surface is marginally testable cy R K&J
@SSIa >= 1 - surface is difficult to test
