如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: v Gy8Qu> SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord 'tgKe!-@ u.XQ& 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: )cJ#-M2 <O<LYN+( (1) 使用 Zygo 干涉儀 u+m,b76 函數 @VFA(zoom #, surface #, height) %ysZ5:X Surface is testable for @VFA < 1.0 }T2xXbU Surface is not testable for @VFA > 1.0 xw5d|20b !^oV # (2)使用 QED 干涉儀 2}6%qgnT- 函數 @SSIa(surface #, zoom #, height) 2B0W~x2= 0 <= @SSIa < 0.5 - surface is readily testable YY((#"o;l 0.5 <= @SSIa < 1 - surface is marginally testable - YqYcer @SSIa >= 1 - surface is difficult to test
