Imaginary and real parts of the dielectric function of the layer semiconductor PbI2 were found using the result of the pseudopotential method zone structure of electron energy spectra calculations. This enabled to calculate optical parameters of the crystal, in particular, absorption, and reflectivity and refraction spectra. There is a good agreement between the result of the reflectivity spectrum calculations and the experiment data.
