Confocal Laser Raman Microscope

The Raman spectroscopy analytical facility consist of a confocal Raman spectrometer attached to a petrographic microscope with motorized mapping stage. This setup contains three different lasers and two detectors, which allows for Raman spectroscopy and Photoluminescence detection in the visual (VIS) and near-infrared (NIR) range. Possibly our scope of analysis will be extended in the future with detection in the ultraviolet range (UV).

The instrument consist of the following components:.

- Raman spectrometer with VIS-CCD camera

- Petrographic microscope and motorized mapping stage

- Resolution x,y better than 1 um

- Resolution z better than 2.5 um

- High speed mapping and depth profiling capability

- Argon laser 488 nm and 514 nm wavelength

- Diode-laser 785 nm wavelength

- Statistical software for background subtraction and peak fitting

- Statistical software for PCA and map construction

- Peak identification software

- Spectral databases for minerals, inorganic and organic substances
