Abstract

An optical assembly includes a transparent substrate having a first major surface and a second major surface. The transparent substrate includes one or more damage layers disposed between a first non-damage layer and a second non-damage layer. Elongated laser-induced damage tracks are disposed within the damaged layer(s) to form at least one area pattern so that light directed toward the transparent substrate at an angle that exceeds a predetermined viewing angle (θ) is scattered by the plurality of laser-induced damage tracks. Alternatively, if light is directed toward the transparent substrate at an angle that is less than the predetermined viewing angle (θ), it is transmitted by the transparent substrate.
