Emil Busch: Pioneer in Optical and Photographic Lens Design

Emil Busch Optische Anstalt was founded in 1845 by Emil Busch (1820-1888) in Rathenow, Germany. The company initially gained recognition by producing microscopes, telescopes, and other optical instruments. By the end of the 19th century, it had become one of the major optical manufacturers in Germany. With the rise of photography, Emil Busch began producing high-quality lenses for cameras. In 1865, the company developed the "Busch Rapid Aplanat" lens, which was considered revolutionary in the world of photography. This lens allowed for faster exposure times and sharper images, making it an important innovation in the field.

At the beginning of the 20th century, Emil Busch Optische Anstalt continued to produce more sophisticated and advanced photographic lenses. The company designed lenses in various formats and for different applications. It also focused on the production of optical devices, such as binoculars and telescopes, for both military and civilian purposes. In 1927, the majority of the company's shares were acquired by Zeiss. Although the firm continued manufacturing cameras, it stopped producing lenses. After World War II, the company was closed down. In its place, the East German government established the firms VEB Rathenower Optische Werke and VEB Augenoptik "Hermann Duncker."
