KW1 KBr IR Windows for FTIR Liquid Cells, Multiple Sizes
Price range: $23.00 through $621.00
KBr IR Windows for FTIR Liquid Cells – Multiple Sizes
Product Description
Potassium bromide (KBr) crystal provides high infrared transmission
and a broad transmission wavelength range. It is widely used in
Fourier transform infrared spectroscopy (FTIR), spectrophotometers
and infrared optical systems.
KBr is commonly used for spectroscopic prisms, transmission windows
and lenses. These polished KBr windows are suitable for FTIR liquid
cells, demountable liquid cells and other laboratory infrared
spectroscopy applications.

Handling & Storage
KBr is highly soluble in water and sensitive to moisture. To maintain
optical performance, the windows should be handled in a dry environment
and stored in a sealed, moisture-protected container when not in use.
