It replaces the photosensitive plate on the focal plane of the spectrograph with an exit slit. There are prism monochromators and grating monochromators. When a beam of composite light enters the entrance slit of the monochromator, it is first converged into parallel light by an optical collimator, and then dispersed into separate wavelengths by a diffraction grating. The different angles at which each wavelength leaves the grating are used to re-image the exit slit by the focusing reflector.
