Microscope

Description: The Professional, Bausch & Lomb’s first high-end microscope, was on the market by 1877 and, with a full set of accessories, could cost as much as $200. Bausch & Lomb renamed it the American Type Microscope, Model K, Professional in the 1890s, boasting that it “may be considered as the highest attainment in microscopical construction in design, solidity and practical utility of the various parts.”; This example is a compound monocular with coarse and fine focus, double nosepiece, trunnion, circular mechanical stage, elaborate sub-stage diaphragm and condenser, support for sub-stage mirror, and tri-leg base. The inscription on the base reads “Bausch & Lomb Optical Co. / ROCHESTER N.Y. AND NEW YORK CITY.” A note in the Accession file states that the serial number is 11088, indicating a date around 1892. At that time, Bausch & Lomb serial numbers appeared on a card in the microscope box, and not on the microscope itself.; Ref: Bausch & Lomb Optical Co., Price List of Microscopes, Objectives and Accessories (Rochester, N.Y., 1883), pp. 24-25.; Bausch & Lomb Optical Co., Microscopes, Microtomes, Apparatus for Photo-Micrography, and Bacteriology (Rochester, 1896), p. 43.
