Infrared Wire Grid Polarizers for FTIR Spectroscopic Analysis

A wide range of infrared wire grid polarizers is manufactured by Specac for FTIR spectroscopic analysis.

Polarizer Applications

Achieving optimum sensitivity for reflectance measurements

Measurement of thin films on reflective surfaces

Studying the orientation effects of polymers, single crystals, and other types of molecules

Polarizer Substrates

Barium fluoride (BaF₂)

Germanium (Ge)

Calcium fluoride (CaF₂)

Thalium bromoiodide (KRS-5)

Zinc selenide (ZnSe)

The infrared wire grid polarizers have a grid periodicity of 4000 lines/mm, which allow them to provide excellent throughput and high extinction coefficients over the 5000 cm⁻¹ to 285 cm⁻¹ range. The polarizer has a thin profile that makes it perfect for FT-IR applications where there are space limitations.

Usable in Conjunction with Spectrometer Accessories

The polarizers can be directly fitted into the aperture ports of all Benchmark™ baseplate compatible accessories available from Specac. Accessories include the Gateway™ horizontal ATR, Silver Gate™ Evolution ATR, Golden Gate™ ATR systems, and the Tornado™ and Cyclone™ long pathlength gas cells. These polarizers can even be used with 3″ x 2″ Polarizer Rotator Slide Mount offered by Specac.
