An experimental set‐up for reflectance spectra measurements is presented. It is characterized by a high degree of precision, normal incidence of light and an energy range of 2‐6 eV. Computer analysis of the reflectance spectra is described. A multilayer model of the suface layer as well as the effective medium approximation theory are used. Results for implanted GaAs and for epilayers ZnSe/Zn 3 P 2 are discussed.
