About Laboratory and Handheld Raman Instruments Raman instruments are used to identify and break down the chemical composition of physical materials based on the inelastic scattering of monochromatic light obtained when the material or sample is exposed to a light source, usually a laser source. This method is called Raman spectroscopy, and it is used to provide a fingerprint by which molecules can be identified. In this process, the sample is illuminated with a laser beam, due to which electromagnetic radiation is emitted. This electromagnetic radiation is then collected, through a mon...more >>
