Compound Binocular Microscope

Circa 1700s | Object # 0161.0084

Inscribed, “R. & J. BECK / LONDON 6725," this brass compound microscope with adjustable binocular body tubes was designed by W. H. Wenham in 1861. A triangular base supports the limb, which has an adjustable inclination angle through a series of holes in the limb that fit a tabbed hinge plate. Coarse focus is achieved through a set of knobs that move the inner pillar tube up and down through a rack gear set. The top of the pillar contains a fine focus knob. A circular stage contains a central aperture and has a slide carrier to assist in translating specimens during viewing.
