James M Jonza, Michael F Weber, Andrew J Ouderkirk, Carl A Stover: Optical film. Minnesota Mining and Manufacturing Company, John A Fortkort, March 16, 1999: US05882774 (529 worldwide citation)

Birefringent multilayer optical films in which the refractive indices in the thickness direction of two adjacent layers are substantially matched have a Brewster angle (the angle at which reflectance of p-polarized light goes to zero) which is very large or is nonexistant. This allows for the constr ...

Andrew J Ouderkirk, Michael F Weber, James M Jonza, Carl A Stover: Optical polarizer. 3M Innovative Properties Company, William D Miller, August 1, 2000: US06096375 (88 worldwide citation)

A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two ...
