Auxiliary Lens for M-Series Stereo

$140.00

This auxiliary lens fits the Unitron series M stereo microscope objectives. The inside diameter of the mount is XXX mm. It appears that the mount may be missing an internal clamp ring. There is a shallow recess where such a ring might have been held captive (these rings are typically used to preserve the finish of the objective by protecting it from direct contact with the ends of the clamping screws). The auxiliary lens does mount very securely, even without this ring.

The glass itself is in virtually perfect condition. I could not see any flaws in the finish on either outer surface, and the cement layer shows no voids. The black anodize ring does show a bit of fading. This lens will halve the magnification indicated on the microscope while greatly increasing the working distance.
