Standard Infrared Polarizers

Fabricated with a grid periodicity of 4000 lines/mm, these polarizer offer excellent extinction coefficient and transmission throughput characteristics with enhanced performance at short wavelengths for precision applications. Infrared substrate materials include as standard: calcium fluoride (CaF₂), barium fluoride (BaF₂), zinc selenide (ZnSe), germanium (Ge), and thallium bromoiodiode (KRS-5).

These polarizers are compatible with Specac's GS57300 series of Bench Mount Polarizer rotators.  In addition, 38 mm clear aperture GS57000 series Infrared Polarizers may be mounted in FTIR Polarizer Rotator for in-compartment polarization experimentation with  baseplate mounted accessories such as: Golden Gate ATR, Silver Gate Evolution ATR, and Gateway Horizontal ATR systems, and the Cyclone and Tornado long pathlength gas cells.
