KCl Substarte

KCl Substarte

Introduction:

Potassium Chloride (KCl) is hygrosopic. The crystal often applied for infared transmission windows and FTIR spectrophotometers. The KCl windows have low refractive index and high threshold damage. So it's very useful for sputter barrier windows in CO2 lasers.
