Spectroscopic ellipsometry in the infrared spectral range 250-5000 cm -1 is used for analysis of the dielectric response of Zn 1-x-y Be x Mg y Se and Zn 1-x-y Be x Mn y Se crystals grown by a high-pressure Bridgman method. Ellipsometric spectra display features in the spectral range 390-500 cm -1 as
