Julius Laack (later Laack Söhne) in Rathenow (Brandenburg, Germany) 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 camera applications as well as enlargers and projectors.[1] [2] An advertisement in 1934 claimed that over 500,000 lenses had been produced by Laack and Laack Söhne.[3]
