Abstract
A polarizer is provided comprising a subwavelength optical microstructure wherein the microstructure is partially covered with a light-transmissive inhibiting surface for polarizing light. The inhibiting surface can include a reflective surface, such as a metalized coating. The subwavelength optical microstructure can include moth-eye structures, linear prisms, or modified structures thereof A polarizing structure is further provided comprising a plurality of moth-eye structures stacked on one another for polarizing light.
Claims8
An optical polarizer film comprising a substrate having a subwavelength moth-eye structure including peaks and valleys, and a plurality of spaced apart and substantially parallel light-transmissive inhibiting surfaces covering at least a portion of the substrate and providing polarization.
A polarizer comprising at least one subwavelength optical microstructure including an undulating surface that includes a plurality of spaced apart and substantially parallel light-transmissive inhibiting surfaces in at least some raised areas of the microstructure.
