The world's first spectroscope was invented by Joseph von Fraunhofer in 1814. For his discovery in the area of spectroscopy he was crowned as Knight in 1824. Spectrograph’s main function is to disperse light into its different wavelength components allowing the investigation of a specific wavelength region of the optical spectrum. It is this property that makes these instruments a vital tool for astronomic studies, from understanding the composition of Sun to analysing rocks on Mars with today’s state of the art Exploration Rovers.
