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 ...
