WebA practically meaningful definition of a grating spectrometer is the measurement of the width at half height (FWHM) of a single spectral line. In practice, the resolution depends on the resolving power of the grating, the effective focal length of the system, the set slit width, the optical aberration of the system, and other parameters. R∝ M-F/W WebA diffraction grating is an optical element, which separates (disperses) polychromatic light into its constituent wavelengths (colors). The polychromatic light incident on the grating is dispersed so that each …
