Surface haze resulting from a rough surface of a substrate is reduced by coating the rough surface with a smooth surface coating of sufficient thickness to smooth out the rough surface. More particularly, a pyrolytic coating of fluorine doped tin oxide deposited on a glass surface usually has average peak to valley distances equal to about 5 to 25% of the coating thickness that results in surface haze viewing the coated glass by the unaided eye. A silica coating film having a thickness greater than the distance between the peaks and valleys of the tin oxide coating e.g. about 100 to 2000 Angstroms is deposited over the tin oxide coating to reduce the surface haze. <IMAGE> |
