如果採用 Code V 軟體，那麼可以用 SAGF 函數計算面深(Sag)量： ]GCw3r(!
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord YPq:z"`-y4
be]/ ROP>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: n@" <NKzh
;V?(j 3b[
(1) 使用 Zygo 干涉儀 6@FhDj2X
函數 @VFA(zoom #, surface #, height) }aXS MxCd
Surface is testable for @VFA < 1.0 qxHn+ O!h
Surface is not testable for @VFA > 1.0 kRb JK
QfPw50N;
(2)使用 QED 干涉儀 pr4y*!|Y$
函數 @SSIa(surface #, zoom #, height) 4^nHq 4_
0 <= @SSIa < 0.5 - surface is readily testable V6((5o#
0.5 <= @SSIa < 1 - surface is marginally testable
(V'w5&f(L
@SSIa >= 1 - surface is difficult to test
