Raman Spectrometer

Raman Spectroscopy

Raman spectroscopy is a widely used analytical tool for the identification and characterization of materials. It uses inelastic optical light scattering by the interaction with the molecular vibrations and rotations in the sample. The frequency of Raman scattered light is unique to each type of vibration and therefore Raman spectrum can give the signature of the different bonds present in the sample.

Raman scattering has been extensively used in physical sciences, chemical sciences, forensics, pharmaceutical studies, geology and material science. The main components of Raman spectrometer includes laser sources, diffraction grating and detector. Appropriate notch filters and dichroic mirrors form essential optical components of a Raman system.
