如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: ]MP6VT
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord x;Jy-hMNl
J_A5,K*r|
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: Iw$7f kq

(1) 使用 Zygo 干涉儀 <k&Q"X:"
函數 @VFA(zoom #, surface #, height) Hb;#aXHSd
Surface is testable for @VFA < 1.0 -P<e-V%<
Surface is not testable for @VFA > 1.0 AVA

(2)使用 QED 干涉儀 'lym^^MjL+
函數 @SSIa(surface #, zoom #, height) {?
jr
0 <= @SSIa < 0.5 - surface is readily testable M38QA
0.5 <= @SSIa < 1 - surface is marginally testable x\Bl^1&
@SSIa >= 1 - surface is difficult to test
