Description
Commercially manufactured binocular microscope oculars and head, with four lenses, in an original case.
The instrument has been engraved with the maker’s mark ‘Ernst Leitz Wetzlar’ on a circular black enamelled plate. Each of two paired lenses (designated ‘1’ and ‘3’) are similarly marked.
The main object and accessories are contained in a tan leather box with a crimson velvet lining and a padded silk lining to the inner lid. The company name ’E.Leitz, Wetzlar.’ appears on the lid top, in gilding. A later Royal Society classification ‘Z.R.S.1’ has been glued above the maker’s mark.
Ernst Leitz GmbH (est.1869) German instrument making company specialising in optical systems was founded by Ernst Leitz I (1843–1920). The company, based at Wetzlar in the state of Hesse, Germany, made microscopes and introduced a fully binocular system in 1913.
