如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: 2KJ1V+g@a6 SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord B(5c9DI` qRB7Ec_ 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: q!lP"J p.K*UP (1) 使用 Zygo 干涉儀 -*ELLY[ 函數 @VFA(zoom #, surface #, height) ^))RM_ic Surface is testable for @VFA < 1.0 eVz#7vqv Surface is not testable for @VFA > 1.0 msx-O=4g F2I 5qC/ (2)使用 QED 干涉儀 x~DLW1I 函數 @SSIa(surface #, zoom #, height) PGn);Baq 0 <= @SSIa < 0.5 - surface is readily testable /R8p] 0.5 <= @SSIa < 1 - surface is marginally testable GHc/Zc"iX @SSIa >= 1 - surface is difficult to test
