Electro Optic GmbH was founded in late 1945 and started the development of a camera in 1946. Production of the Elca, a simple 35mm camera for 24x24mm format began in 1947. In 1948 the company changed it's name to ELOP, Vereinigte Elektro-Optische Werke GmbH and the Elca II was developed. The following tear the company moved to nearby Flensburg and the Elca II went into production.

The company developed a 35mm SLR camera, including a six element Elolux f1.9 50mm lens. Financial problems lead to bankruptcy in 1951, but a new company, UCA Werstätten für Feinmechanik und Optik GmbH was founded the same year. The Ulca II became the Ucanett. In 1952 Ulca was taken over by Agfa and camera production came to an end.
