The tube consists of 2 telescopic tubes that are both the same size. At the top is the eyepiece and at the bottom is a revolver that can hold 2 easily interchangeable lenses. The tube can move vertically using a rack mechanism on the back, which is controlled by 2 side screws for coarse focusing. The front of the tube has a screw marked in millimeters from 0 to 9, used for fine focusing.

The pillar is straight at the top, where the tube is placed, and then continues into a concave section that serves as an arm. This is where the quadrangular, black iron stage sits with its comprehensive mechanical system allowing the sample to be moved sideways, forward, and backward using screws. Below the stage and supported on the pillar is a condenser diaphragm, which can move vertically using a rack mechanism. At the top of the pillar is the plano-concave mirror with an arm that gives it a wide range of movement. The microscope body is supported by the pedestal with an articulated screw that enables it to tilt. The pedestal comprises a cylindrical tube supported on a tripod base. One of the legs bears the manufacturer's inscription: "R&J BECK. 31 Cornhill. LONDON." Toward the end is the instrument number: "7202."
