如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： [9S\3&yoh
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord PGZ .\ i
1.WdxMpW9
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: \q#s/&b
WS6pm6@A*!
(1) 使用 Zygo 干涉儀 MI o5Y`T
函數 @VFA(zoom #, surface #, height) @ @$=MS N
Surface is testable for @VFA < 1.0 #q. Q tDz
Surface is not testable for @VFA > 1.0 Qp8. D4^@3
{6Tw+/`P
(2)使用 QED 干涉儀 P7r?rbO"
函數 @SSIa(surface #, zoom #, height) ='f<_F D
0 <= @SSIa < 0.5 - surface is readily testable q]Gym 7o
0.5 <= @SSIa < 1 - surface is marginally testable DE3>F^ j
@SSIa >= 1 - surface is difficult to test
