C.C. Harrison & Joseph Schnitzer Globe Lens

With wheel of stops, approx. 10" focal length. Unlike the earlier Sutton water-filled lens, the Globe Lens focused on a flat field. On June 17, 1862, C. C. Harrison and J. Schnitzer of New York received a patent for the "Globe Lens" (U.S. 35.605) in which two deeply-curved cemented doublets were arranged about a central stop in such a way that the exterior surfaces formed a sphere. This lens covered 90 degrees at f/30 was an instant success. Charles C. Harrison was a daguerreotypist, camera maker, and inventor. He began manufacturing high-quality cameras about 1849. He is known to have made daguerreotype apparatus in 1854-1855 at White & Elm Sts.. He died Nov.23, 1864. Ex Spira Collection.
