Description

This brass microscope was once lacquered but at a later date the lower part was painted black, its signature and serial number are not clearly visible, but presumably 5..42. It is obviously one of the smaller Zeiss stands type VII, these were produced from before 1889 until circa 1922.
This stand is rather sturdily built, it was recommended for laboratory use, it cannot be inclined. The microscope has a simple square stage with spring clips, under the stage a dovetailed holder for a special condenser or a diaphragm, in the holder a condenser lens. There is a flat mirror in a bracket on a swing arm, allowing for oblique illumination. Coarse adjustment is by sliding tube, fine adjustment by means of a micrometer screw.
The objective type ‘3’ and the Huygens eyepiece type ‘4’, signed ‘R Winkel / Gottingen’ are probably not original.
