Potassium bromide, 98.5%

Potassium bromide is transparent from the near ultraviolet to long wave infrared wavelenghths (0.25-25 µm) and it has no significant optical absorption lines in its high transmission region.

It is used widely as infrared optical windows and components for general spectroscopy because of its wide spectral range. In infrared spectroscopy, samples are analyzed by grinding with powdered potassium bromide and pressing into a disc.

Potassium bromide is used also as a veterinary drug, as an antiepileptic medication for dogs and cats.
