A spectrometer is a scientific instrument which is used to separate and measure spectral components of a physical phenomenon. [1]

The basic function of a spectrometer is it takes light, breaks into its spectral components, digitises the signal as a function of wavelength, reads it and displays it through a computer. [2]

Types of Spectrometers - [1]

  1. Optical Spectrometer - They show the intensity of light as a function of wavelength or of frequency.
  2. Mass Spectrometer - These are used to identify the amount and type of chemicals present in a sample by measuring the mass to charge ratio
  3. Time-of-flight spectrometer - The energy spectrum of parties of known can also be measured by determining the time of flight between the two detectors.
  4. Magnetic Spectrometer - This measures the energy spectrum by inserting a fast charged particle into a constant magnetic field (B) and varying B for spectrum of different types of particles.
