Potassium Bromide

Potassium Bromide (KBr) is a crystalline compound of potassium and bromide with a rock-salt type structure. It is used in optical applications in the UV, Visible, MWIR, and LWIR wavebands. KBr has a melting point at 730°C and needs to be used in a moisture free environment as the polished surfaces degrade in a moist atmosphere.

The IR grade of Potassium Bromide (KBr) can be used as the windows for Fourier Transform Infra-Red (FTIR) spectroscopy. The wavelength range covers from 0.23 to 25µm with a high value of transmission. This transmission averages about 90% from 0.3 to 20µm. Typical applications for Infrared Optics using Potassium Bromide is, for example, lenses, prisms, spectroscopic cells, and windows.
