如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： w:%3]2c
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord gFlUMfKh
:H($|$\h
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: 0Snl_@s
X:Z4QqT
(1) 使用 Zygo 干涉儀 j"o8]UT/
函數 @VFA(zoom #, surface #, height) 5%M 'ewu
Surface is testable for @VFA < 1.0 w/+ e
Surface is not testable for @VFA > 1.0 gI<e=|J6w
<Vucr
(2)使用 QED 干涉儀 6$]@}O^V
函數 @SSIa(surface #, zoom #, height) nv>|,&;
0 <= @SSIa < 0.5 - surface is readily testable uFPJ}m[>5
0.5 <= @SSIa < 1 - surface is marginally testable _"Yi>.{]
@SSIa >= 1 - surface is difficult to test
