Julius Laack, later Julius Laack Soehne,[1] was a camera and lens maker, based at Curlandstrasse 60, Rathenow (Brandenburg, Germany).[2] The company seems to have started in 1884.[3] McKeown[4] 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. In 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 Gunthe.[5]

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 cine lenses.
