Potassium bromide (KBr) is the most widely used material for infrared beamsplitters with coverage of the normal 4000 – 400 cm^-1 mid-IR spectral region. Spectral Systems Photon Pro™ coating for our KBr beamsplitters extends the usefulness of the KBR into the Near-IR with full coverage of the region 8000-380 cm^-1 at better than 85% efficiency. Thus a single beamsplitter can be used for many applications requiring FT-IR, FT-NIR or FT-Raman.
