Potassium Chloride (KCl) is a commonly used material in FTIR spectroscopy. With low absorption and high damage threshold and a low index of refraction, KCl is an ideal candidate for use in CO2 laser applications as an inexpensive, disposable material. KCl is water soluble and the windows should be protected from exposure.
Firebird provides these in several uncoated stock configurations but can provide customized and coated to your specifications.
