Compound microscope built by Georg Friedrich Brander. The instrument is mounted on wooden box containing the accessories. The side-pillar is attached to the box, which also carries the adjustable illumination mirror. The stage inserted in the pillar is fitted with a sophisticated micrometer for moving specimens laterally. Focusing is performed by turning a knob screw that slides the body-tube vertically. The wooden tube is partly covered with rayskin. The field lens is present in the eyepiece; there is also a micrometer, consisting of a point advanced by means of an iron screw. Provenance: Lorraine collections.
