The spectral resolution of Raman spectroscopy depends on several factors such as laser wavelength, grating groove density, and spectrometer focal length. Thus, a resolution can be improved by selecting a higher wavelength laser or a grating with higher groove density. However, the focal length of the spectrometer plays the most crucial role, defining the achievable spectral resolution.
Indeed, selecting a suitable laser wavelength minimizes interference and enhances spectral clarity, while gratings with higher groove densities disperses light more finely, thus improving resolution, and a proper focal length selection ensures precise spectral measurements with minimal aberrations.
