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; to about 0.31 &lgr; , where &lgr; 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; to about 0.125 &lgr; 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.
