Description
Raman microspectroscopy is used principally to identify organic molecules, polymers and inorganic compounds up to a depth of 2 µm. It utilizes molecular vibrations, in a fashion similar to infrared spectroscopy. A laser beam incident on the sample surface interacts with the sample phonons, causing photon emission at a lower wavelength by Raman scattering. Weak signal measurement is a key challenge in the design of a good Raman spectrometer.
