KBr Substrate

KBr Substrate

Introduction:

Potassium Bromide (KBr) crystal is water-souble, and it is easily deliquescent. That cannot be chemically polished. It's commonly used for transmission windows, FTIR spectrophotometers and beam splitters for spectrophotometers. The Kbr substarte and windows are soft and Hygroscopic.
