Raman spectrometer Horiba Jobin-Yvon LabRam HR800 used for registration of spectra of Raman scattering. A main aims are identification of the studied substances in solid, liquid or gaseous states, phase diagnostic of inclusions in minerals, assessment of the degree of crystallinity of the substance, studies the transformation of substances in the chemical and electrochemical reactions, studies of changes in biological tissues. A built-in microscope allows to obtain information with micrometer objects. Confocal optical scheme enables the most  detailed images and analyses to be obtaibed with speed and confidence.
