如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: 8J2UUVA`1
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord 9tCF m.m

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: "?"+1S

(1) 使用 Zygo 干涉儀 D}nRH@<`
函數 @VFA(zoom #, surface #, height) V24FzQ?z:.
Surface is testable for @VFA < 1.0 ]"\sd"
Surface is not testable for @VFA > 1.0 g'.(te |

(2)使用 QED 干涉儀 QY1|:(
函數 @SSIa(surface #, zoom #, height) FyllVrK
0 <= @SSIa < 0.5 - surface is readily testable ,T+.xB;Q@
0.5 <= @SSIa < 1 - surface is marginally testable *1U"uJno
@SSIa >= 1 - surface is difficult to test
