What is the classification of spectrometers There are many types of spectrometers and many classification methods. Spectrometers can be divided into two categories based on the spectral decomposition principle used by them: classical spectrometers and new spectrometers. 

Classical spectrometers are based on the principle of spatial dispersion (spectroscopy); The new spectrometer is an instrument based on modulation principle, so it is also called modulation spectrometer. Classical spectrometers can be divided into prism spectrometers, diffraction lattice spectrometers and interference spectrometers according to their dispersion principle. Spectrometers can be divided into: Vacuum ultraviolet (wide ultraviolet) spectrometer (6~200nm) Ultraviolet spectrometer (185~400nm) Visible light spectrometer (380~780nm) Near infrared spectrometer (780nm~2.5m) Infrared spectrometer (2.5~50m) far infrared spectrometer (50m ~1mm) Application of spectrometer 

Spectrometers are widely used in agriculture, astronomy, automotive, biology, chemistry, coating, chromium measurement, environmental detection, thin film industry, food, printing, paper, Raman spectroscopy, semiconductor industry, composition identification, color mixing and matching, biomedical applications, fluorescence measurement, gemstone composition identification, Oxygen concentration sensor, vacuum chamber coating process monitoring, film thickness measurement, LED measurement, emission spectrum measurement, ultraviolet/visible absorption spectrum measurement, color measurement and other fields are widely used.
