High index of refraction coated light management films

摘要

A polarization sensitive optical substrate comprises a planar surface and a first thin film applied to the planar surface. The first film has a thickness of lambda/4/n, where lambda is the wavelength of light incident upon the first film and n is the refractive index of the first film. A prismatic surface is optionally also thin film coated, and is in opposition to the planar surface.
