colorPol® polarizers

colorPol® polarizers are dichroic glass polarizers, made from a highly durable soda-lime glass containing silver nanoparticles. Like all dichroic polarizers they let the desired  polarized light pass and absorb the unwanted polarization. Different types of polarizers are available to suit a wide field of applications operating at UV wavelength range (340 nm - 420 nm) and VIS, NIR and MIR wavelength range (475 nm - 5.0 μm).

All polarizers can be processed like glass or silicon wafers, while being thin like foil polarizers. UV radiation and most chemicals cause no damage. They have a large acceptance angle of ± 20° and a high accuracy of polarization axis.

Due to the special manufacturing process, colorPol® polarizers can be highly customized to match your application perfectly.
