Raman spectroscopy is a vibrational spectroscopy that uses light scattering to infer vibrational spectra of solid samples. It can help in identification of molecular compounds, bonding geometries, chemical mapping, etc. It can be used for applications as wide ranging as pharmaceuticals, forensic science, polymers, thin films, semiconductors and even for the analysis of fullerene structures and carbon nano-materials. Our Horiba Aramis spectrometer has confocal and micro-mapping capabilities, and it offers a selection of 325, 532, 633, and 785 nm excitation lasers.
