Abstract:
A method of forming a polarizing material is provided including exposing a layer of dichroic material to activating light illumination to provide an ordered structure with a distinguished absorption axis and thus photo-induce polarization, and fixing the induced polarization by polymerization of the dichroic layer. Novel polarizing materials formed thereby are also provided. By selectively exposing regions of the dichroic material to differing activating radiation, different regions with different polarization axes can be created. The polarizing material can also be provided with a coating or coatings to alter the spectral responses, and a stack formed of a plurality if dichroic layers can be provided.
