Julius Laack, later Julius Laack Soehne, was a camera and lens maker, based at Curlandstrasse 60, Rathenow (Brandenburg, Germany). The company seems to have started in 1884. McKeown lists a ferrotype camera from 1895, and a number of folding plate cameras. Laack lenses were used on smaller-format cameras at least up to the Second World War. During the time of the German Democratic Republic the company became state-owned and was part of VEB Rathenower Optische Werke (ROW), together with Emil Busch and Nitsche and Günther.
Laack lenses, especially the Pololyt, appear on other German companies' cameras including the Altissa Altiflex and Altix, Welta Reflekta and KW Pilot Super. Laack also made a range of cine lenses as well as filters. In addition, Laack worked on other photographic implementations, such as film testers.

Laack was first and foremost an optical company making lenses for cameras, binocluars and microscopes. Laack produced a wide range of lenses for still photo and cine cameras as well as enlargers. An advertisement in 1934 claimed that over 500,000 lenses had been produced by Laack and Laack Söhne. Well-known names are Dialytar, Pololyt and Texon. A listing of Laack lenses is provided as a separate entry.
