He made optical glass, an achromatic telescope, and objective lenses. He developed diffraction grating and also invented the spectroscope. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines.
The German research organization Fraunhofer Society, which is Europe's biggest Society for the advancement of applied research, is named after him. Fraunhofer lines are used in astronomy to determine the composition of celestial bodies. His epitaph reads Aproximavit sidera, Latin for 'He brought closer the stars.'
