Spectrometers use various principles to divide a mixed beam of light into multiple pure beams, generally used for spectral analysis.
A device for measuring the intensity of a spectral line at different wavelength positions using a photodetector such as a photomultiplier tube. The structure consists of an incident slit, a dispersion system, an imaging system and one or more outgoing slits. A dispersive element is used to separate the electromagnetic radiation from the source into the desired wavelength or wavelength region, and the intensity is measured at the selected wavelength (or scanning a band). It is divided into monochromator and polychromatic instrument.
