Light spectroscopy has existed for over 200 years, beginning with an experiment conducted by Bavarian physicist Joseph von Fraunhofer, during which he discovered dark lines in the sun’s light spectrum.  Eventually, this discovery led to the development of spectral line analysis to infer the chemical composition and temperature of the sun’s atmosphere.  Today, light spectroscopy allows scientists to gather information about a wide variety of objects.

Due to the need for very small amounts of light to be used, scientists are in a perpetual journey to discover more sensitive spectroscopy methods.
