Product Description

FT-IR Infrared Polarizers

applications include: the study of orientation effects of single crystals, polymers, and other molecules, measuring thin films on reflective surfaces, and obtaining optimum sensitivity for reflectance measurements.

These polarizers are available on a choice of calcium fluoride (CaF2), barium fluoride (BaF2), zinc selenide (ZnSe), thalium bromoiodiode (KRS-5), or germanium (Ge) substrates. With a grid periodicity of 4000 lines/mm, they offer high extinction coefficients and excellent throughput over the range 5000 cm-1 to 285 cm-1. The thin profile of this polarizer makes it suitable for FT-IR applications in which there are space constraints.

 

These polarizers are designed to fit directly into the aperture ports of all Specac Benchmark™ base plate compatible accessories, such as the Golden Gate™ ATR, Silver Gate™ Evolution ATR, Gateway™ horizontal ATR systems, and the Cyclone™ and Tornado™ long path length gas cells. Alternatively, these polarizers are compatible with Specac’s GS12500 3” by 2” Slide Mount Polarizer Mount.
