ABSTRACT:
A visible range synthetic light polarizing element is provided, the optical and polarizing properties thereof having been selectively effected by regulated exposure of said polarizing element to ultraviolet irradiation. The ultraviolet irradiation can be either polarized or non-polarized, but in either case, is at intensities greater than that produced incidentally or by ambient ultraviolet irradiation sources. The resultant light-polarizing element is characterized by its heightened luminous transmittance, an improvement accomplished without departure from good polarization efficiency (i.e., greater than 99.9%).
