The ‘sister cities’ of Jena and Rochester (USA) have a lot in common: Here, as there, an optics industry has developed since the 19th century together with suppliers. While in Jena the collaboration between Carl Zeiss and Ernst Abbe significantly furthered optics research, soon after in Rochester, local industrialists George Eastman (Eastman Kodak) and Edward Bausch (Bausch & Lomb) founded an optics institute at the university. Since then there have been many changes. Today, both regions are enormously strong locations for the optics and photonics industry and research.
