The main transparency range of KBr potassium bromide crystal substrate is 0.22μm~30μm, covering NIR, NIR and FIR bands. It has very low absorption loss in the NIR wavelength of 4000-400cm-1.It is commonly used as transmission windows or beam splitters for FTIR spectrophotometers or spectrometer,The Kbr substrate and windows are soft and hygroscopic, have the good resistance to mechanical shock. Is the ideal for FTIR Spectroscopy.
We can provide various sizes of KBr crystal substrate and other products, to ensure good parallelism and transmittance, if you want to know more about KBr crystal products, please feel free to contact us.
