SUMMARY
Raman spectroscopy requires the use of optical filters to effectively isolate inelastic scattering from elastic scattering. The elastic scattering, known as Raleigh scattering, occurs at the same frequency as the laser beam, necessitating the use of a notch filter to block this frequency. A diffraction grating is commonly employed to further enhance the separation of the desired Raman signal from background noise. The optical filter must be precisely tuned to the wavelength of the illuminating laser to achieve optimal results.
