general specifications

 

colorPol® polarizers are dichroic glass polarizers. They feature a high contrast ratio and a high transmittance. Standard colorPol® polarizers are available for the UV wavelength range
(340 - 415 nm) and for the VIS and NIR range (450 - 5,000 nm). For the IR range
(1,200 - 3,000 nm) there are special versions of high transmittance (HT) polarizers with a transmission up to 98%. Each colorPol® polarizer is characterized by its maximum of polarization and the contrast ratio in the guaranteed wavelength range (>= 1,000:1, >= 10,000:1 and >= 100,000:1, indicated in the product name by C3, C4 and C5 respectively).


The wavelength of maximum polarization and contrast of a polarizer is determined by the chosen technological parameters. The performance of a custom-made polarizer can be optimized to a customer's requirements by trading off transmittance and extinction ratio at a given wavelength.The wavelength range of effective polarization spans to the UV region (colorPol® UV: 340 nm to 415 nm) and the visible and near infrared region (colorPol® VIS and colorPol® IR: 450 to 5,000 nm). Standard dimensions range from 5 x 5 mm2 up to 50 x 30 mm2. Various thicknesses are available ranging from 0.2 to 2 mm raw or laminated on a carrier glass.

 

Based on the unique colorPol® technology CODIXX is the world’s first producer of patterned polarizers. CODIXX as the manufacturer of colorPol® S polarizers can let them have arbitrary shaped areas with different directions of polarization. The areas can also have different spectral characteristics.

colorPol® polarizers

  • are flat like foil polarizers

  • can be processed like glass or silicon wafers

  • are resistant against UV radiation and chemicals

  • have large acceptance angles

  • are resistant against temperatures up to +400 °C
