Abstract
Abstract A glass assembly includes a glass substrate having an induced transmission filter adhered to one surface thereof. The filter includes at least one coating formed of a layer of reflective material between two layers of dielectric material. The reflective material can be one of aluminum, silver, gold and copper. The dielectric material can be one of zinc oxide, indium oxide, titanium dioxide and tin oxide. The coating can be applied to one side of a plastic carrier sheet and an abrasion resistant material can be applied to the other side of the carrier sheet to form a film. The film can be adhered directly to the glass or to an intermediate plastic sheet. In an alternate embodiment, the coating can be applied to a surface of a glass sheet and covered with an abrasion resistant material which can be another sheet of glass.
