| Creator Name | Ernst Leitz Wetzlar, Microscopes Manufacturer, 1849- |
| Description | This is a brass monocular microscope, featuring a U-shaped heavy base for stability, connected to a tube (called arm) in which the microscope's components are securely screwed in. The illuminator, a circular mirror that rotates, is very worn. On top of it, there is a square metal piece with a round hole in the middle (called stage), and a rotating plate beneath it, which features holes of different sizes to allow a regulated amount of reflected light to come in (called aperture). On the top side of the stage, two adjustable flaps (called stage clips) can be loosened by twisting the screws; this would have allowed positioning of the microscopic glass. The stage is engraved with "E. Leitz Wetzlar N. 4600".
The final mounted piece is the eyepiece holder. The eyepiece is removable and adjustable by twisting its position in the holder, and consists of a long tube featuring lenses on both ends.
This type of mycroscope was used for various purposes, such as cells, tissues, and microorganisms studies; to examine blood samples, tissues, and other biological specimens.
