Codixx Nanotechnology Polarizing Filters

(Nanowerk News) CODIXX extends the colorPol® polarizer product family with the colorPol® MIR to cover the mid infrared range.
With the steady raise of applications in the MIR range like matter analysis or thermography, the polarizer is thrusted into the spotlight.
CODIXX's answer to this challenge is the new colorPol® MIR.
This filter comes with a very large bandwidth and provides high extinction ratios of above 10,000 : 1 (40dB) within 2.0 µm - 4.5 µm (in wavenumbers 5,000 cm2 - 2,222 cm2) and above 1,000 : 1 (30dB) within 1.5 µm - 5.0 µm (in wavenumbers 6,666 cm2 - 2,000 cm2). Transmittance properties up to 90% underline the entitlement to a high performance polarizer.
nanoparticle-coated polarizing filters
Based on the unique colorPol® technology for doping of sodium silicate glass with prolate silver nanoparticles all colorPol® polarizers provide high temperature stability up to + 400° C, resistance against rough environmental influences, against the most chemicals, UV radiation and bleaching as well as the ease applicability to name a few.
Dimensions ranging from 1 x 1 mm2 up to 100 x 50 mm2 and different shapes are available. In addition, the filter is offered in standard versions with diameters of 12.5 mm, 25.0 mm as well as 0.5 inches and 1 inches, respectively.
CODIXX is a manufacturer of optical polarizers for the infrared, the visible and UV spectral range. On the cutting edge of nanotechnology, its leading role is a result of steady development since it was founded in 1998.
