如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: -)~SM&
SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord K6olYG>
;us%/kOR
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: i%6;

(1) 使用 Zygo 干涉儀 _{|D
函數 @VFA(zoom #, surface #, height) BIj=!!
Surface is testable for @VFA < 1.0 yAN=2fZm
Surface is not testable for @VFA > 1.0 [p=*u,-

(2)使用 QED 干涉儀 D/=5tOy
函數 @SSIa(surface #, zoom #, height) &gI ~LP
0 <= @SSIa < 0.5 - surface is readily testable 3z]+uv+2J
0.5 <= @SSIa < 1 - surface is marginally testable A_;8IlW
@SSIa >= 1 - surface is difficult to test
