Potassium bromide window (uncoated) 40 mm dia x 3 mm thickness

Potassium Bromide is one of the most useful materials for general purpose spectroscopic windows and applications where sensitivity to moisture is unimportant.
Cut and polished quality crystal windows.

KW 225 (OTTOKEMI) Potassium bromide window (uncoated) 40 mm dia x 3 mm thickness - 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.
