The results of optical properties investigation of glass surface modified by surface ionic-exchange paste (SIEP) are given in the article. The action of paste is based on the surface ion exchange process, leading to formation of a system of microblocks and microcracks (Patent of Russian Federation №2238919). The light scattering forward by modified glass surface layer is characterized by a narrow scattering indicatrix in the region of small angles. A size distribution function of heterogeneous scattering centers and partial depolarization of initially linearly polarized light were measured. It was find that the characteristics of a light scattering for a modified glass layer differ essentially from similar characteristics for glass surface frosted by a method of chemical etching with fluor containing composition. In work the data of a light scattering by modified glass samples with thing Au layers deposited on glass surface in vacuum (thickness 50-200 nm) are represented also. The broad scattering indicatrix back (scattering angle from -900 up to -1800) is observed in this case. A low intensity of scattered light was characteristic for small angles.
