Item

Title

Chevallier-Type Top Mounted Microscope

Description

The compound microscope is made from lacquered brass. The pillar is screwed into a socket screw that secures the microscope to the top of the case. At the top of the pillar is an inclination joint which allows the microscope to be angled for observation. The body-tube can be slide into an attachment on the arm. Coarse focusing is achieved by sliding the body-tube through the draw-tube closer or further from the stage. The rectangular mechanical stage has an attachment that holds the specimen in place as well as a bulls-eye condenser which is attached via a pin. The specimen can be adjusted vertically by the thumbscrew on the side. The microscope also has a sub-stage iris diaphragm which rotates via a pin attachment. There is also a thumbscrew located underneath the stage that controls the space between the iris diaphragm and the stage. The sub-stage mirror is one-sided and is held in a gimbal. The case is made from mahogany and has compartments to hold the dissembled microscope. The case has a functional lock and key.
The microscope comes with the following accessories: 2 ocular lenses, 2 objectives with brass canisters, 1 stage bulls-eye condenser and 1 key.
Condition

Cosmetically: The brass shows some signs of age and use, however, it is in good condition.
