"The quality of the polarizers is really good: excellent extinction coefficient Practically no maintenance is needed"
Specac manufacture a range of infrared wire grid polarizers for FT-IR spectroscopic analysis. 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™ baseplate compatible accessories, such as the Golden Gate™ ATR, Silver Gate™ Evolution ATR, Gateway™ horizontal ATR systems, and the Cyclone™ and Tornado™ long pathlength gas cells. Alternatively, these polarizers are compatible with Specac’s 3” by 2” Slide Mount Polarizer Mount.
