Potassium Bromide Crystal Substrates Description

Potassium Bromide (KBr) crystal is water-soluble, and it is easily deliquescent. It cannot be chemically polished. It’s commonly used for transmission windows, FTIR spectrophotometers and beam splitters for spectrophotometers. The potassium bromide crystal substrates and windows are soft and Hygroscopic.
