NIRaman Fiber Probe

Main features:

  • Multichannel fiber optic probes
  • NIR and Raman channels can work simultaneously providing hybrid modelling opportunities
  • On-line Raman and NIR spectroscopy
  • Flexible and robust for industrial applications in harsh environment
  • Compatible with all Raman and NIR spectrometers

FlexiSpec® product line includes innovating NIRaman Combi probes.

Raman and NIR spectra contain qualitative and quantitative information on the chemical composition and physical properties of the substance. Both are able to provide critical product and process information during production.

Multichannel fiber optic probes (patent pending), have been developed by art photonics in cooperation with “Measure Analyze Control”. The first commercial version was designed for in situ NIR diffuse reflectance and Raman measurements of solids, powders, or liquids. The unique feature of the probe is that NIR and Raman channels can work simultaneously providing hybrid modelling opportunities that yield novel insights in the field of spectroscopy. The probe shaft is electrically heated to prevent moisture condensation on optical windows.
