Setup with the confocal micro-Raman optical system is devoted for Raman scattering spectra registration. Raman scattering spectroscopy can be used for the analysis of bulk materials, thin layers, powder and solutions. Unknown materials can be identified using the 8000 spectra containing spectral library. Measurements of various carbon allotropes (diamond-type carbon, graphene, graphene oxide), organic and inorganic materials, surface-enhanced Raman scattering measurements using silver or gold nanoparticles are performed.
