Overview
The Confocal Raman microscope is an optical microscope through which an monochromatic laser source is directed at a sample. The sample absorbs energy and scatters the light at different wavelengths which is then read with a CCD camera. Raman is based inelastic scattering due to characteristic vibrational modes of the material being studied.
