Polarizers are useful for enhancing sensitivity in grazing angle measurements using specular reflectance accessories and for molecular orientation studies. Polarizers attenuate radiation from polarized lasers, polarize radiation from unpolarized lasers and can be used in pairs to both polarize and attenuate. ICL wire grid polarizers are available for wavelength ranges from 3µm to 15µm.These wire grid polarizers are created by etching sub-micron spaced grooves (2400 grooves per mm) using holographic methods. Each polarizer is mounted in a protective 5mm thick anodized aluminum ring that protects both faces of the polarizer. The outside diameter (OD) of the 25mm polarizer is 25mm with a clear aperture of 18mm. The OD of the 50mm polarizer is 50mm with a clear aperture of 34mm. An optional polarizer mount is available that will fit the universal 2" W x 3" H slide mount found in virtually all spectrophotometers and many specular reflectance accessories.
