This microscope is signed on the stage Carl Zeiss, Jena. It is an example of the
Stand 1B from 1914 . It was the top-of-the-line Zeiss model of its day. Among its
features are the large Zeiss mechanical stage with rotation and centering adjustments
and the full substage with swing-out iris diaphragm. It is constructed entirely of
brass with lacquered and black enamel finishes. The microscope is about 13 inches
tall in the inclined position as shown in some of the images with the
drawtube closed. The wide tube makes this model particularly useful for photomicrography.
Coarse focusing is by rack and pinion and fine focusing utilizes the Berger designed
arrangement shown below. The large mechanical stage with centering adjustments and
locking mechanism can revolve about the optical axis with the horizontal and vertical
movements calibrated and measured with verniers. The substage consists of a rack and
pinion focusing Abbe condenser with swing-away iris diaphragm and off-centering
adjustments for oblique illumination. The mirror is double sided with plane and
concave glasses. The microscope is supplied with five objectives with canisters,
a sliding objective changer nosepiece and three objective mounts, five oculars, the Abbe condenser with iris,
and the storage case with internal fittings with lock but no key.
The microscope is mechanically in good condition. The surface finishes are original
and in good condition. The mirrors are in good condtion. The case with brass handel is also
in good condition. This is a fine example of the famous Zeiss "Jug-handle" microscope
as made by the premier German manufacturer. This design was very influential and was
copied by a number of other manufactures.

This microscope is an example of the Zeiss 1B model. It is based on a
design by Max Berger of Zeiss first introduced in 1898
(Zeitschrift fur Instrumentenkunde, vol. XVIII, 1898, pp. 129-133). The major innovations of this design were a new type of fine adjustment and a limb having an integral handle (now, often referred to as a "Jug-Handle" microscope). The various version of this stand differ primarily in the type of stage attached to the instrument. The 1B model incorporates the Large Mechanical Stage.
