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%.
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
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.
Applications
Polarizers are used in a wide range of diverse optical devices to pass or stop polarized light, to modulate or reduce brightness, diminish noises and lots more. Because of their excellent properties and outstanding adaptability, colorPol®-polarizers are usable for many applications:
- Optical sensor devices
- Illumination engineering
- Instrument filters for laboratory equipment in microscopy, ellipsometry, spectroscopy, polarimetry
- Photoelasticity, surface inspection
- Fiber related sensors
- Polarization dependent optical isolators
- Optical communications engineering and data storage
- Electro-optical modulators
- High-temperature LC-Displays
- High-temperature LC-Shutters
- Lyot-Filter
The colorPol® technology
The new technology is used to create uniformly oriented prolate silver particles near the surface of soda lime glass. Due to the prolate silver particles, absorption of already polarized light occurs and non-polarized light becomes linearly polarized passing the so treated glass. The absorption is selective in reference to the wavelength of light. Beside the standard products, the flexible technology allows for the production of customized polarizers with special spectral characteristics.
