Potassium Chloride – KCL2
lenses, windows, mirrors, filters and prisms
Because of its low absorption, high damage threshold and low index KC1 is used a laser protection windows. Potassium Chloride is 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.
