KBr Window (25x4mm)

Potassium Bromide (KBr) optical windows are key lenses for Fourier Transform Infrared (FTIR) analysis. They offer a wide transmission range from visible light to far infrared, used for making solid sample pellets or as windows for liquid cells. Grown via high-purity crystal processes and precision-polished to reduce scattering, KBr windows are indispensable for studying molecular structures, chemical bond changes, and oil component identification in infrared spectroscopy analysis.
