Patent ID: 8817376

Claim:
A glass article comprising a vacuum-deposited optical coating and a vacuum-deposited easy-to-clean coating on top of the optical coating, the glass article being shadow free across an optically coated surface of the glass article, wherein: the optical coating comprises a plurality of periods consisting of a layer of high refractive index material H having an index of refraction n greater than or equal to 1.7 and less than or equal to 3.0, and a layer of low refractive index material L having an index of refraction n greater than or equal to 1.3 and less than or equal to 1.6, the layer of high refractive index material H being a first layer of each period and the layer of low refractive index material L being a second layer of each period; and an SiO 2 capping layer having a thickness in a range greater than or equal to 20 nm and less than or equal to 200 nm applied on top of the plurality of periods.
