Abstract: The paper describes a study of some optical parameters of the amorphous chalcogenide glass of the composition Sb32As5S48I15. Dispersion of the refraction index was determined by the direct method on the prism made of the investigated glass, and the obtained results served as the basis for determining the value of the wavelength corresponding to the characteristic frequencies of elementary oscillators (λ0), and total oscillator force of the electronic system (A). The recorded transparency spectra were used to determine spectral distribution of the absorption coefficient (α), with and without taking the reflection into account. It was shown that the reflection can be neglected in the first approximation. The values of the absorption edge (λg), optical band gap (Eg), as well as the width of the tails of localized states in the band gap region (Γ0), were also determined.
