Binocular Microscope, 1902

This instrument is a binocular microscope or magnification viewer made in Germany by Carl Zeiss Jena in 1902. It is designed to view specimens and dissections instead of samples. The microscope is quite well preserved: its black-enameled frame is in good condition and keeps all its original components and parts. The manufacturers name is engraved in different places, both in the frame and the lenses. This article comes in its original mahogany wood case, also signed and in very good condition.One of the eyepiece-holders located at the top of the instrument bears the serial number 66574 engraved in the metal. The other shows the engraved manufacturers logo with the inscription CARL ZEISS JENA. Actually, the manufacturer was Carl Zeiss and Jena is the name of the German city where he founded his workshop. This happened in 1846 and from then on the firm grew to become one of the most flourishing optical manufacturers in Germany.
