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 μm in thickness. The method may further comprise cutting the polarizing layer into wafers.
