Potassium Bromide (KBr) is a material commonly used in FTIR spectroscopy. We have long experience of supplying the KBr windows of standard (catalogue) sizes for the commonly used instruments from Perkin Elmer, Nicolette, Bruker Optics, Pike, etc. Most popular drilled KBr windows such as KBr 32x3mm (demountable cell windows) for spectroscopy are in our product line. They fit to most accessories and cell holders
- Excellent Transmission from 250nm to 26µm
- Good Resistance to Mechanical Shock
- Ideal for FTIR Spectroscopy
- Drilled KBr windows - all standard sizes
- Packing: All KBr optics carefully packaged into plastic boxes with silicagel and sealed with special moisture protective film.
