  • Patent number: 6589657
    Abstract: An optical coating and a method of coating a substrate are provided. A first layer is deposited adjacent to a substrate. The first layer has an optical thickness of about 0.27 &lgr;0 to about 0.31 &lgr;0, where &lgr;0 is a reference wavelength corresponding to a spectral region bound by or in the visible spectrum. A second layer having an optical thickness of about 0.1 &lgr;0 to about 0.125 &lgr;0 and a refractive index from about 2.2 to about 2.6 is deposited. A third layer having a refractive index from about 1.46 to about 1.52 is deposited. The optical coating provides broadband anti-reflection performance, and the thin second layer facilitates high throughput production of the optical coating.

  • Publication number: 20030043464
    Abstract: An optical coating for a substrate comprises an amorphous material, which includes titanium oxide and one or more additives. Titanium oxide and the additive in an oxidized state do not form a solid solution. The amorphous material may be used in low-emissivity, double low-emissivity, and anti-reflection coatings. A method for coating a substrate comprises depositing a first anti-reflection layer of a dielectric over a substrate, depositing a metallic layer over the anti-reflection layer, and depositing a second anti-reflection layer of a dielectric over the metallic layer. At least one of the first anti-reflection layer and the second anti-reflection layer comprises the amorphous material.
