The prism method was applied to the refractive index investigations for glasses in their transparency domain. The experimental values of the refractive index were described by means of the Sellmeyer formula and Herzberger pentanomial. The fitting coefficients were determined to estimate the zero-dispersion and dispersion value for these materials in their domain of transparency.
