This instrument is supported on a stand and has various parts: an elongated, cylindrical optical tube containing the lens, the field lens and the eyepiece where the user looked through. The eyepiece also has a lens. On one side of the cylinder, there was a pinion rack which was used to regulate the tube up and down and to move it closer or further away from the object to be examined. The cylinder is rounded off with another much smaller lens which is situated above the slide or cover-slip, where the sample is placed and which holds the condenser lenses (4); there is a mirror in the bottom part which is struck by the light, so illuminating the sample. Joined to the main cylinder is another smaller one which has a small wheel at the top. It is supported on two iron legs.

This piece was used at primary schools for observing small objects of which the microscope provided a highly magnified image via a system of lenses.
