Abstract

An approach to determining optical constants of cadmium sulfide films by spectrophotometric measurements is reported. Reflectance and transmittance were recorded as functions of incident angles, which were fitted by calculations at a fixed wavelength. The optical constants at this wavelength and the film thickness can be accurately determined. Since the film thickness does not change, for uniaxial films there are only four unknowns left, which can be recovered by four independent spectrophotometric measurements.
