Charged Particle Sources
Did You know?
Raman Microscope is a spectroscopic imaging instrument that allows highly magnified visualization of a sample by harnessing the Raman scattering from molecular vibrations. Typically these systems consist of an optical microscope, an excitation source such as a monochromatic laser, and a sensitive light detector attached to a monochromator. A number of different configurations of imaging modes are now readily available such as direct and chemical imaging, hyperspectral imaging, and confocal Raman microscopy, which offers especially high spatial resolution. Raman microscopy is often used in the study graphene, carbon nanomaterials, and pharmaceuticals as well in forensics and geology. The name Raman is in honour of an Indian physicist from the Province of Madras whose fundamental work on light scattering was rewarded by the 1930 Nobel Prize in Physics.
