A Carl Zeiss Jug Handle Compound Monocular Microscope, Ca 1900
A Carl Zeiss Jug Handle Compound Monocular Microscope.
Germany, circa 1900.
Marked "Carl Zeiss, Jena, No 74292", to the tube, lacquered brass and black finish frame tilting on a spur-shaped base, rack and pinion fine focusing, triple objective, mechanical circular stage, the original fitted mahogany case with accessories.
Measurement: H. 38 cm.
catalogue Note: This microscope was manufactured in 1899, making it a very early example of its type. It is based on a new design by Max Berger of Zeiss first introduced in 1898. The major innovations of this design were a new type of fine adjustmentand a limb having an integral handle (now, often referred to as a "Jug-Handle" microscope). While this microscope is perfectly suited for conventional work, this particular model was made for the purposes of photomicrography and projection. Accordingly, the main tube appears to be made of aluminum presumably to reduce the weight on the fine adjustment mechanism thus allowing it to be more sensitive and responsive when the microscope is inclined in the horizontal position (later versions of this model dispensed with the use of aluminum).
Literature: Zeitschrift fur Instrumentenkunde, vol. XVIII, 1898, pp. 129-133.
Estimate: 150-300
