Zeiss

A Carl Zeiss teaching eyepiece adapter. The central eyepiece fits into the standard eyetube of any monocular microscope. It has a pointer system that can be introduced into the field of view and moved to point out specific parts of the slide being studied. On the end of the side tube is a second eyepiece which has independent focusing which ensures the image is in focus for both observers. Date from approximately 1950 but still works perfectly.

This is a Carl Zeiss Achro-Aplanatic condenser with a numerical aperture of 1.4. Flange fitting with iris diaphragm. Very good condition.

Mechanical stage with coaxial controls and a fixed condenser lens that has a flip in/out lower lens to make the condenser appropriate for the objective being used.
