Important features of colorPol® polarizers

  • Thin like foil polarizers
  • Handling like glass and silicon wafers
  • Resistant to UV radiation and most chemicals
  • Wide acceptance angle for incident radiation
  • Operating temperature range up to +400°C (laminated: -20°C to +120°C)

The contrast ration in defined to be k1:k2, where k1is the transmittance of a polarized beam passing the filter and k2 is the transmittance of a polarized beam blocked by the filter.


Contrast ratios ≥ 100,000:1, other thicknesses, shapes or dimensions on request. Reflection losses can be minimized by antireflection coating. AR-coatings are available for different wavelength ranges as V-coating or wide-band version.
