GS57000 Series IR Wire Grid Polarizer

Standard IR Wire Grid Polarizers

Specac series infrared polarizers are a range of high-quality holographic wire grid polarizers fabricated on a variety of infrared-transmitting substrates, and available in sizes from 25 mm to 71 mm diameter clear aperture.

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 series of Bench Mount Polarizer rotators.  In addition, 38 mm clear aperture  series Infrared Polarizers may be mounted in Specac's Benchmark™ FTIR Polarizer Rotator for in-compartment polarization experimentation with Specac Benchmark™ 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.
