20x Eyepiece Pair for Stereo Zoom

Description

This is a used pair of Bausch & Lomb stereo microscope oculars. They are intended for use in the StereoZoom series of instruments. They are of earlier manufacture, having the red-engraved nomenclature on the clear anodized aluminum barrels.

Magnification � 20x
Eye relief � 9mm
Barrel diameter � 23.2mm
Field-of-view index � 12mm (diameter of object field when microscope zoom set to 1x)

These oculars are in very fine optical condition, but cosmetically I would rate them somewhere between ‘fair’ and ‘good’. There are some identification marks engraved in the barrel, and the clear-coat anodizing shows some deterioration. The upper black-anodized bezels are very worn. The base of the barrels have slight crimps from having been dropped. The crimps come nowhere near interfering with the image (the diaphragms are quite small compared to the diameter of the barrel). However, it does mean that unthreading the diaphragms in order to mount reticles will most likely not be easy, if even possible (see second photo).
