WebOverview The diffraction grating of a spectrometer determines the wavelength range and partially determines the optical resolution that the spectrometer will achieve. Choosing the correct grating is a key factor in … WebThe spectral resolution of a spectrometer refers to its ability to resolve spectral features and bands into their respective components. In dispersive array spectrometers, spectral resolution is dependent on the slit, diffraction grating, and detector.
