In this paper the optical properties of CdSe thin films obtained by spray pyrolisis are presented. The films are prepared by Sodium Selenosulphate (Na₂SSeO₃) and Cadmium Chloride (CdC_l2) mixing in aqueous environment. Optical parameters of the films (refractive index, absorption coefficient and optical bangap) were calculated from transmittance spectra. The obtained values of the optical bangap are compared with the result obtained by other deposition methods.
