Near IR (NIR) Spectral Libraries

 This unique collection of over 6,000 NIR spectra is the biggest and newest NIR spectra collection available on the market. 

All spectra were measured using a FT-NIR Spectrometer equipped with Integrating Sphere (IS) Accessory.  


Spectral range in wavenumbers units: 4200-10000 cm-1

Spectral range in wavelength units: 2.4 – 1 micrometers, 2400-1000 nm

Standard resolution: 4cm-1 in the spectral range

Customized resolution: Upon special request the spectra can be delivered in customized resolution for better correspondence with the spectra you have measured on your NIR instrument

Extensive sample information with spectra*

Lists of compounds/spectra in each database are available in pdf format
