The former Fraunhofer glassworks in Benediktbeuern was the field of activity of the optician Joseph von Fraunhofer from 1807 and 1819 . A small exhibition in the original glassworks reminds of this time.

In 1805, the Munich manufacturer Joseph von Utzschneider acquired the buildings of the Benediktbeuern monastery, which was secularized in 1803, and set up two separate glassworks there for the production of utility glass and optical glass as well as an optical institute . His partner, the optician Joseph von Fraunhofer, worked there between 1807 and 1819. Fraunhofer initially worked under Pierre-Louis Guinand and became operations manager in 1811. He developed new grinding machines and types of glass for optical glasses (streak-free flint glass ), which decisively improved the image quality of lenses. From 1814 Fraunhofer and Utzschneider were the sole shareholders of the independent Optical Institute. For astronomy , Fraunhofer’s improvement of the achromatic lens pair invented a few years earlier in England was significant . Instead of joining the two lenses with cement , Fraunhofer placed them one behind the other with an air gap. This brought additional degrees of freedom to correct optical aberrations . “Fraunhofer achromatic lenses” are still used today in amateur astronomy.

In 1819 the Optical Institute was relocated to Munich because Utzschneider sold the Benediktbeurer building complex to the Kingdom of Bavaria out of financial difficulties and only kept the utility glassworks. In the former Fraunhofer workplace there is now a museum that is run by the Fraunhofer-Gesellschaft . The exhibition in the historic glassworks shows two large melting furnaces with stirrers for glass production, display boards, optical instruments and tools for glass and metal processing.
