STUDENT MICROSCOPE:
c. 1890
Unsigned, probably German or French
Serial Number: None
DESCRIPTION
This is a small, but heavy for its size, monocular microscope most likely manufactured in Germany or perhaps France in the late 19th to early 20th century. It is about 12 inches tall in use. The stage is about 2 3/4 X 2 inches. This microscope is built upon a
conventional “Continental” design horseshoe or Y-shaped foot of black painted metal. Rising from the foot is an inclination joint to which is attached a cylindrical brass pillar that supports the stage and the rest of the microscope, including a bar limb. Under the stage is a wheel of aperture diaphragm. There are two stage clips on top of the stage. Below the stage is a 30mm diameter plano-concave mirror that is attached via a gimbal on an articulated extension coming down from the stage. Coarse focus is by moving the body tube of the
microscope up or down within a brass sleeve that is attached to the top
of the pillar with a bar limb. The body tube of the microscope is of brass. A single eyepiece (unmarked) is with the instrument.
There is a draw tube that can extend the mechanical tube length from four to eight inches. At the base of the body tube is a single tapering objective lens. A bullseye condenser is articulated to the front of the main ring supporting the tube. The microscope weighs about 3 pounds.
