Polarizer covers mid infrared range

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. The new colorPol® MIR 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 cm-1 - 2,222 cm-1) and above 1,000:1 (30dB) within 1.5 µm - 5.0 µm (in wavenumbers 6,666 cm-1 - 2,000 cm-1). Transmittance properties up to 90% underline the entitlement to a high performance polarizer. 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 of 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 inch, respectively.

CODIXX, which will appear at the SPIE Defense and Security Symposium (16-20 March), with representatives at Booth 823, is a manufacturer of optical polarizers for the infrared, the visible and UV spectral range.
