Rollei (German pronunciation: ) was a German manufacturer of optical instruments founded in 1920 by Paul Franke and Reinhold Heidecke in Braunschweig, Lower Saxony, and maker of the Rolleiflex and Rolleicord series of cameras. Later products included specialty and nostalgic type films for the photo hobbyist market.
Originally named Werkstatt für Feinmechanik und Optik, Franke & Heidecke, the company renamed into Rollei-Werke Franke & Heidecke GmbH in 1972, Rollei-Werke Franke & Heidecke GmbH & Co. KG, in 1979, and Rollei Fototechnic GmbH & Co. KG in 1981.
After being purchased in 1995 by Samsung Techwin, part of the South Korean Samsung Group, it was sold back to its internal management in 1999. In 2002, it was bought by a Danish investment group and renamed Rollei GmbH in 2004.
In 2005/2006, the company headquarters moved to Berlin and the company was split into two different companies: Rollei GmbH in Berlin, owner of the Rollei brand and selling various OEM equipment, and Rollei Produktion GmbH in Braunschweig, an equipment factory which became Franke & Heidecke GmbH, Feinmechanik und Optik.
