如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： gWj-@o\
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord ` o)KG,
7|}4UXr7y
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: 1EU4/6!C
(Yewd/T
(1) 使用 Zygo 干涉儀 \ eHOHHAGW
函數 @VFA(zoom #, surface #, height) 5>}$]d/o
Surface is testable for @VFA < 1.0 Nh \vWAz9
Surface is not testable for @VFA > 1.0 xs= ~N
56AC%_ g>
(2)使用 QED 干涉儀 R+LKa Z
函數 @SSIa(surface #, zoom #, height) qvn.uujYS
0 <= @SSIa < 0.5 - surface is readily testable tpWGmj fo>
0.5 <= @SSIa < 1 - surface is marginally testable Lx,=Up.
@SSIa >= 1 - surface is difficult to test
