Patent ID: RE39215

Claim:
A coated article comprising: a temperature-sensitive substrate having a melting point lower than glass; an anti-reflection coating including a plurality of layers substantially transparent to visible light, at least one two of said layers being a DC reactively sputtered high refractive index material layer having a refractive index higher than said substrate and between approximately 1 . 9 and 2 . 2 and selected from the group consisting of tin oxide, indium oxide, zinc oxide, tin-doped indium oxide, antimony-doped tin oxide, tin-bismuth oxide, and tin-zinc oxide, and at least one other layer being a low refractive index material layer having a refractive index lower than said substrate , wherein said high refractive index material layer farthest from said substrate having an optical thickness of about one- quarter to one - third wavelength at a wavelength between 480 and 560 nanometers .
