Square and Rectangular Potassium Chloride Windows

Potassium Chloride (KCl) has a wide transmission range from 210nm to 20m. While cheap, KCl is hygroscopic . This limits its application to protected environments or for short term uses such as prototyping. When exposed to free air, KCl optics will "rot". Please let us know if you would like more information on KCl.
