Schematic diagram of a typical Raman spectrometer.
Description
Light is directed onto the sample and scattered back at a different optical frequency than that of the external light. After the scattered light passes through lenses and mirrors, it encounters a diffraction grating. This disperses the light based on its different wavelengths and separates the scattered light into its various spectral components. Next, light is directed towards a detector, which records the intensity of each wavelength, creating the Raman spectrum displayed on a computer.
