如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： B?M& j
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord {v3?.a$ u
i`k{ } !F
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: Tfsx&k\
D1G9^7:^E
(1) 使用 Zygo 干涉儀 'P'f`;'_DC
函數 @VFA(zoom #, surface #, height) 3+: F2sjt
Surface is testable for @VFA < 1.0 z[vHMJ
0
Surface is not testable for @VFA > 1.0 3 UXaA;
/ i: c!l9
(2)使用 QED 干涉儀 Twq/ Y07M
函數 @SSIa(surface #, zoom #, height) Xg <R+o
0 <= @SSIa < 0.5 - surface is readily testable nC6 ;:uM
0.5 <= @SSIa < 1 - surface is marginally testable Ec2?'*s
@SSIa >= 1 - surface is difficult to test
