    摘要： The invention is directed to a method for preparing visible light optical polarizers using a non-halide silver salt and any glass composition that the non-halide silver salts is soluble, provided that the glass composition, including the silver salt, was a halide content that is, on a molar basis, 10% or less than the silver content, on a molar basis, of the glass composition. The silver containing glass is hydrogen reduced prior to stretching to form an optical polarizer. The invention enables one to form a visible light polarizer having a polarizing layer thickness in the range 10-40 μm in which the silver particles have a surround index sufficiently removed from the blue polarizer region to allow good contrast.

    摘要： Disclosed are methods for making an enclosure having a three-dimensionally shaped glass wall portion comprising an initial step of shaping a glass charge into a preform having a preform cross-section corresponding in shape to a smaller cross-sectional shape for the three-dimensional glass wall portion. At least a surface portion of the preform is then finished if necessary to remove any visible optical surface defects therefrom and/or to meet geometric tolerances, and the preform is drawn along an elongation axis perpendicular to the preform cross-section to reduce or draw down the preform in size to the smaller cross-sectional shape for the three dimensional glass wall portion. The smaller cross-sectional shape or sections thereof are then tempered to provide a strengthened glass wall portion having a compressively stressed surface layer thereon.
