Raman Spectroscopy is used to identify a material by detecting its molecular vibrational and rotational modes. A laser light is shined onto the material and the scattered light is used in the spectroscopy measurements. Since the excitation source laser intensity is often six to eight orders of magnitude greater than the Raman scattered signal, edge pass filters are required to block the wavelength of the scattered laser beam while transmitting the wavelength shifted Raman scattered signal. Download the full article for in-depth information on how edge filters are used to their fullest extent within Raman spectroscopy.
