Abstract
The results of measurements concerning spectral dependences of transmission and reflection coefficients both for porous and two-phase glasses are presented. Relative estimations have been performed for transmission and reflection coefficients of examined samples. Optical characteristics, such as the dispersion of refractive index and absorption coefficient, have been found for porous glasses. Porosity of the material and the sizes of micropores have been determined from the optical characteristics of glasses with the assumption of identity and uniformity of pores.
