Patente US20040126549 - P-polarizer with large z-axis refractive index difference

A multilayer optical polarizing film has optical layers whose refractive indices substantially match along orthogonal in-plane x- and y-axes, and that mismatch along a z-axis by at least 0.1 and in some cases by at least 0.15. The film has substantially no reflection bands at normal incidence, and for...http://www.google.es/patents/US20040126549?utm_source=gb-gplus-sharePatente US20040126549 - P-polarizer with large z-axis refractive index difference $Patente US20040126549 - P-polarizer with large z-axis refractive index difference$
