Reflection-repressed wire-grid polarizer

摘要: A reflection repressed wire-grid polarizer (10a-e) for polarizing incident visible or infrared light (12) and selectively repressing a reflected polarization includes at least three layers (18a-d) disposed on substrate (14). layer (18a) has an array of parallel metal wires (22) with period less than half the wavelength light. reflection-repressing grid (18c) inorganic non-dielectric material which is optically absorptive light, dielectric (18b, 18d) material.
