Abstract

The reflection–transmission method for determining the optical constants of a film on a substrate has been examined and a computer program for the solution of the equation system has been written. A new method involving only transmittance data in a limited wavelength region has been worked out and has been found to give accurate results. The computer program for this method gives directly n and k curves from the transmission curve.
