When this instrument was made by the Zeiss firm, it was a top of the line model. Among the accessories included with the microscope
are three objectives with their brass canisters, three eyepieces,
and a camera lucida. Under the stage is a diaphragm wheel. In
addition, this instrument was supplied with polarizing apparatus. Note that the fine adjustment knob is located below at the rear of the stage. In later models, the fine adjustment knob was place at the top of the limb.
The analyzer prism mounts on the end of the eyepiece.
The polarizing condenser is attached to a rotating stage which mounts
on the main stage.
