ABSTRACT:
A wire grid polarizer (100) for polarizing an incident light beam (130), comprising a substrate (505) having a first surface (410) and a second surface (510); and a first array of parallel, elongated wires disposed on the first surface (410). Each of the wires are spaced apart at a grid period less than a wavelength of the incident light; and a second array of parallel, elongated wires disposed on said second surface (420) where the second array of wires are oriented parallel to the first array of wires.
