Raman laboratory

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.

Raman spectrometer

The Raman laboratory is designed for rapid identification and characterization of minerals and microfossils. It contains a confocal Raman spectrometer attached to a petrographic microscope with a motorized mapping stage. The Raman Spectrometer is equipped with a VIS-CCD camera and is suitable for high-speed mapping and depth profiling. It comprise and argon laser 488 nm and 514 nm wavelength, a diode-laser 785 nm wavelength and has a x,y resolution better than 1µm and a z resolution better than 2.5 µm. It is equipped with statistical software for peak fitting and map construction and software for peak identification. Raman maps (i.e. chemical or mineralogical maps) and depth profiles can be constructed in a matter of minutes to hours, depending on resolution (down to 0.3 um) and area (up to centimetres).
