如果採用 Code V 軟體,那麼可以用 SAGF 函數計算面深(Sag)量: `j@1]%&z SAGF(surface_num, zoom_pos, x_coord, y_coord) - Sag of the designated surface at x_coord, y_coord {eI'0== C{pOGc@ 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: QK+,63@D\= P9'`
2c (1) 使用 Zygo 干涉儀 O7
aLW 函數 @VFA(zoom #, surface #, height) vE'{?C=EM Surface is testable for @VFA < 1.0 ,G%UU~/a Surface is not testable for @VFA > 1.0 96<oX:# PBb&.< (2)使用 QED 干涉儀 p__wBUB 函數 @SSIa(surface #, zoom #, height) aH{)|? 0 <= @SSIa < 0.5 - surface is readily testable zaHZ5%{LQD 0.5 <= @SSIa < 1 - surface is marginally testable -)oUb=Lk{ @SSIa >= 1 - surface is difficult to test
