OverviewSpecsFAQsCustomizeDownloadsCool-Tips
High-contrast plate polarizers are thin foil-like dichroic glass polarizers made of prolated silver spheroids embedded in soda-lime glass. These thin polarizers are in turn laminated on a thicker soda-lime substrate with a matching refractive index with the substrate and the foil to ensure no change in the polarizer's spectral characteristics. Thus, the polarizers are less fragile in handling and feature a low wavefront distortion of λ/4. These polarizers are offered with no coating.

  • High-contrast polarizers are available in the ultraviolet, visible, and infrared regions.
  • Contrast ratios are as high as 100,000:1, acceptance angles are as high as ±20 degrees, and transmission is greater than 48 percent with unpolarized light.
  • These polarizers are resistant to cleaning solvents, most acids and bases, and ultraviolet radiation.
