"The quality of the polarizers is really good: excellent extinction coefficient Practically no maintenance is needed"
Specac manufactures 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.
