Abstract:
A glass polarizer having an excellent transmittance and extinction ratio with respect to light in the visible light range including blue using silver halide containing glass as a starting material is provided.A manufacturing method according to the present invention to manufacture glass polarizers is characterized in that borosilicate glass in which silver halide particles are dispersed and deposited by heat treatment is reduced to generate metallic silver particles from at least a portion of silver halide and then, heated for stretching to generate silver halide particles oriented and stretched in the glass.
