First Spectrometer in Year 1859

The first spectroscope was invented in 1859 by the German chemist Robert Wilhelm Bunsen and the German physicist Gustav Robert Kirchhoff. It was used to identify materials that emit light when heated. A spectroscope transforms light into a spectrum using a prim that can be observed through a small telescope. The positions of the lines reveal the chemical composition of the material in question.(1)
