Potassium Chloride - KCL2
lenses, windows, mirrors, filters and prisms
Click here to download PDF version of this page.Because of its low absorption, high damage threshold and low index KC1 is used a laser protection windows. Also used in infrared Spectroscopy as windows, lenses and prisms. The material is water soluble and polished surfaces should be protected from exposure to moisture.
