Abstract

The sensitivity of approximate formulas for determining the optical constants of thin films using measurement of reflectancesR and transmittancesT at normal incidence have been investigated theoretically. The ranges of refractive indexn, absorption indexk,2nk (=ɛ2) andn 2−k 2(=ɛ1) within relative errors of 5%, 10%, and 20% may be obtained. Selected signs of (ɛ1)+ or (ɛ1)− have been determined. Validity of the condition n0 A′=n s A has been also evaluated (A=1−R −T andA′=1−R′−T).
