The paper tackles the results of the research of the borderline of the basic absorption band as well as the optical functions of the solid strata in the CdTe-MnTe row. The spectral dependence of the absorption coefficient in the basic absorption band domain was calculated from the reflection and transmission spectra. The high reflection spectra at the surface of the CdxMn1-xTe thin layers in the domain 6,2eV-1,2eV are also analyzed at room temperature; they enable the calculation of the spectral dependence of the optical constants in this spectral domain. The particularities characteristic to the refection spectra and the optical constants are compared to the spectra obtained from monocrystals and identified to the optical transitions in the spots of high symmetry in the Brillouin area of these crystals.
