The Raman Laboratory

Raman scattering is a versatile spectroscopic technique based on the inelastic light scattering that arises from the interaction of a laser beam with the electronic and vibrational levels of the matter. It is commonly used in many scientific and industrial fields as a non-destructive tool for identifying compounds and providing information concerning the compound structure and composition, and monitoring changes induced by physical and chemical treatment.

Our setup consists of a confocal Raman spectrometer (LabRam HR Evolution – Horiba) attached to a petrographic microscope equipped with 10x, 50x, 50x LWD, 100x objectives, a VIS-CCD camera and a mapping stage. The Duoscan option is also available, which allows mapping of a 20 mm* 20 mm area with a spatial resolution of 0.5 mm. The Raman spectrometer is equipped with two lasers (532 and 633nm), two available gratings (600 g/mm, 1800 g/mm) and has a user-controllable variable aperture confocal pinhole that provides diffraction-limited spatial resolution with maximum signal throughput.

This confocal Raman microspectrometer allows a non-destructive and non-invasive characterization and chemical imaging of several materials (massive samples, thin sections, powders, gem quality single crystals) spanning from rocks and minerals to synthetic compounds, fossils, fluids, fluid inclusions, glasses and much more.
The system is connected to a PC workstation equipped with Labspec 6 software running Windows 10, which enables complete instrument control and data processing.
