Title
American-Style A. S. Aloe & Co Microscope
Description
The American-style compound microscope is made from brass. The monocular microscope stands on a tripod stand which is connected to the pillar. The pillar is split into two by an inclination joint which allows the microscope to be angled for observation. The circular stage is fixed and has a rotatable iris diaphragm with apertures located beneath it. The sub-stage concave mirror is fitted into a gimbal which allows it to be angled to catch the light. Coarse focusing functions via rack and pinion controlled by two thumbscrews on either side of the body-tube. Fine focusing is controlled by a small thumbscrew located at the top of the pillar. The fitted wooden case has a small interior drawer and compartments to hold four ocular lenses. The case also has a lock and key that are still functional.
The microscope comes with the following accessories: 2 ocular lenses: 1" unsigned, 1/2" marked Bausch & Lomb Optical Co. 2 objective lenses placed in marked brass canisters (A. S. Aloe & Co. St Louis, MO), 3/4" and 1/5".
Condition:
Cosmetically: The mirror has some spots on the concave side and a dull, fine speckled appearance on the flat side. 3/4 lens has small nick in the bottom lens.
Optically: The lenses are dirty but functional.
Mechanically: The clips and tiny screws for the clips are missing. The pillar is loose in the base which results in the microscope leaning to one side. The microscope is otherwise functional.
