Jules Duboscq Brass Compound Monocular Microscope

Signed "J. Duboscq of Paris, No. 176", this all-brass microscope was one of many scientific instruments made by the French artisan. The model featured below was redrawn from photographs of the original microscope, which is part of the Billings microscope collection at Walter Reed Army Hospital in Washington DC.

The microscope is over 16-inches tall and rests on a black tripod base that has a spread of slightly over nine inches. The body tube is telescoping and fits into a drum-like cylinder that contains a two-inch lens. A similar cylinder is located in the center of the body tube.

A grooved track is attached to the rear of the body and stage cylinders, each of which has a circular plate at the bottom. A lens is inserted into the top of the lower cylinder and into the base of the upper cylinder. Positioned between the cylinders is a specimen stage, which is attached with a jointed movable arm to the adjustment track. A swivel joint connects the grooved track to the microscope limb and allows inclination of the body tube over a 90-degree range. Focus is achieved by translating the body tube in the grooved track with a small knurled knob.
