This nineteenth century French microscope was made by the fine craftsman Camille S. Nachet. The microscope is one of many derivatives of the basic drum microscope design first introduced by George Adams and Benjamin Martin in the eighteenth century.

This microscope is very similar in basic design and execution to Georges Oberhauser's drum microscope that was produced around the same time period. The body tube is a compound microscope that is mounted on an arm affixed to the base of the microscope. Focus is achieved by a set of threaded rods that move the body tube up and down with respect to the stage through several knobs at the base of the arm. A concave reflecting mirror is positioned in an opening at the base to allow light to be reflected onto the sample. The microscope has interchangeable threaded objectives and a multiple-lens eyepiece.
