如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: 4L bll%[9 SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord :85QwN]\ `mthzc3W 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: !bIE%cq 704_ehrlE (1) 使用 Zygo 干涉儀 d@%PTSX 函數 @VFA(zoom #, surface #, height) _WR/]1R Surface is testable for @VFA < 1.0 :6:,s#av Surface is not testable for @VFA > 1.0 bU \T 7,s5Gd- (2)使用 QED 干涉儀 |It&1fz} 函數 @SSIa(surface #, zoom #, height) Dz&,g+>$J 0 <= @SSIa < 0.5 - surface is readily testable iA<'i8$P 0.5 <= @SSIa < 1 - surface is marginally testable 7|xu)zYB @SSIa >= 1 - surface is difficult to test
