Polarized Glass
Polarized Glass is a modern type of absorptive polarizer made of elongated silver or copper nanoparticles embedded in thin glass plates. These polarizers are more durable, and can polarize light much better than plastic Polaroid film, achieving polarization ratios as high as 100,000:1 and absorption of correctly-polarized light as low as 1.5%. Such glass polarizers perform best for short-wavelength infrared light, and are widely used in optical fiber communications.
