Abstract: A wire grid polarizer comprises parallel grids of composite wires wherein each grid includes a coating stack having at least one high refractive index material coated on an aluminum layer. The coating stack comprising at least one high refractive index material reduces the reflection of the wire grid polarizer from between 40-50% to between 5-10%. Possible candidates for the high refractive index materials include Ge, Si and alloys of these materials having refractive indices greater than 3 with extinction coefficients above 0.2.

Abstract: Optical devices such as eyeglass lenses and digital displays having improved optical characteristics achieved, in part, through incorporation of an index matching system between material layers having different refractive indices.

Abstract: A photochromic polyurethane laminate that is constructed to solve certain manufacturing difficulties involved in the production of plastic photochromic lenses is disclosed. The photochromic laminate includes at least two layers of a resinous material and a photochromic polyurethane layer that is interspersed between the two resinous layers and which contains photochromic compounds. The polyurethane layer is formed by curing a mixture of a solid thermoplastic polyurethane, at least one isocyanate prepolymer, at least one photochromic compound, and a stabilizing system.
