如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： yDegcAn?
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord yy i#Mo
,
"8x8UgG
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: c|B.n] Z
2a`o
&S
(1) 使用 Zygo 干涉儀 xSsa(b
函數 @VFA(zoom #, surface #, height) 0zlb0[
Surface is testable for @VFA < 1.0
4~Vx3gEV:
Surface is not testable for @VFA > 1.0 #~2%)
vgH3<pDiU6
(2)使用 QED 干涉儀 7vrl'^ 1
函數 @SSIa(surface #, zoom #, height) Q
Nh|Wz
0 <= @SSIa < 0.5 - surface is readily testable 5
ZGNz1)?V
0.5 <= @SSIa < 1 - surface is marginally testable K /j3a[.
@SSIa >= 1 - surface is difficult to test
