如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： %B3~t>
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord ?HZp @ &
c w;wv+|k
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: o<2GtF1"o
r );R/)&
(1) 使用 Zygo 干涉儀 j jpY g
函數 @VFA(zoom #, surface #, height) <O x[![SR
Surface is testable for @VFA < 1.0 Rd?}<L
Surface is not testable for @VFA > 1.0 Z5{a7U4z_
2 pS<;k`
(2)使用 QED 干涉儀 E$d3+``
函數 @SSIa(surface #, zoom #, height) #u<Qc T@
0 <= @SSIa < 0.5 - surface is readily testable )oEVafNsT
0.5 <= @SSIa < 1 - surface is marginally testable z(PUoV:?
@SSIa >= 1 - surface is difficult to test
