Silver Chloride (AgCl) Optical Crystals

Silver Chloride (AgCl) is commonly used for infrared transmission windows in gas and liquid sample cells used with infrared and FTIR spectrophotometers in place of Potassium Bromide (KBr) with aqueous samples that would attack KBr optics. It has a wide transmission range and is relatively insoluble in water, but it darkens when exposed to light.
