如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: *M"}z SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord %VnbmoO ow]053:i 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: 6H7],aMg$A :ijAqfX (1) 使用 Zygo 干涉儀 ' MxrQ;|S 函數 @VFA(zoom #, surface #, height) Q@HopiC Surface is testable for @VFA < 1.0 /Sh#_\x Surface is not testable for @VFA > 1.0 1@-Ns [W7CXZDd (2)使用 QED 干涉儀 rh^mJUh 函數 @SSIa(surface #, zoom #, height) &c,kQo+pA 0 <= @SSIa < 0.5 - surface is readily testable -(=eM3o-9m 0.5 <= @SSIa < 1 - surface is marginally testable 4H/fP]u @SSIa >= 1 - surface is difficult to test
