Abstract: An ultra-thin polarizing glass article having two polarizing glass layers separated by a non-polarizing central region. The polarizing glass layers contain stretched or elongated metal particles and the non-polarizing central region contains elongated or stretched metal halide particle. The polarizing article has a thickness less than 200 micrometers.

Abstract: A method for making a polarizing glass article is provided. The method includes first providing a precursor glass containing metal-halide particles. The precursor glass may be encased in a gas-permeable medium. Then, form at least a first polarizing layer and a non-polarizing region in the precursor glass. Bond the polarizing layer to a substrate and removing the non-polarizing region to expose the polarizing layer. Then, separate the first polarizing layer from the substrate to produce an ultra-thin polarizing glass article measuring less than or equal to about 200 ?m in thickness. The method may further comprise cutting the polarizing layer into wafers.
