Paper Abstract

High efficiency glass polarizers have been developed that offer superior design characteristics over plastic, wire-grid and some prism type polarizers. Glass polarizers have transmittance greater than 90%, contrast greater than 500:1 at acceptance angles up to 60 degrees, and excellent resistance to humidity and temperature. High polarizing efficiency is obtained over a bandwidth of about 300nm. The location of the polarized band can be specified within the near-infrared range (800-1800nm). The polarizing effect is due to the resonant absorption of elongated sub-microscopic particles of silver metal aligned along a common axis in the glass. The polarizing mechanism is discussed briefly followed by a review of typical glass polarizer performance, design characteristics and suggested applications.
