WebA diffraction grating is an optical element that divides (disperses) light composed of lots of different wavelengths (e.g., white light) into light components by wavelength. The … WebOther factors are grating, groove frequency and detector pixel size. The optical resolution and throughput of a spectrometer will ultimately be determined by the installed slit. Light entering the optical bench of a spectrometer via a fiber or lens is focused onto the pre-mounted and aligned slit.
