colorPol® Standard Polarizers
Using nanotechnology our colorPol® polarizers offer very high contrast ratios (up to 10 million to 1) and high transmittance (up to 99%.)
colorPol Polarizers
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 (340-410 nm) and for the VIS and NIR range (450-2,700 nm). Additionally, for the IR range (1,200 nm - 2,500 nm) there are special versions of high transmittance (HT) polarizers with a transmission >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
Applications
Polarizers are used in a wide range of diverse optical devices to pass or stop polarized light, to modulate or reduce brightness, or diminish noise. Due to their spectral and physical properties and outstanding adaptability colorPol® polarizers have many applications:
- Optical sensor devices
- Illumination engineering
- Instrumental filters for laboratory equipment in microscopy, ellipsometry, spectroscopy
- 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
The colorPol® 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. The absorption is selective in reference to the wavelength of light. Beside the standard products, the flexible technology allows producing of customized polarizers with special spectral characteristics.
