Product Description
This is a fiber optic ring-light illuminator for use with a stereo microscope. The angled boss where the fiber optic bundle meets the ring-light enclosure fits into the receptacles of several manufactures stereo microscope stands. It is meant to be secured by a clamp screw or collar at that point because there are no other provisions for securing the ring-light to the microscope.
The outside diameter of the enclosure is 3.476 inches. The central aperture is 1.925 inches in diameter. The base of the enclosure has a stepped ring 3.030 inches in diameter with a shallow groove, most likely for attaching a polarizing accessory ring (not provided). The inside of the enclosure is strongly tapered. Overall length of the flexible bundle is 1 meter. The input ferrule is 0.625 inches in diameter and 0.25 inches in length where it steps up to a diameter of 0.715 inches.
The flexible armored bundle is black vinyl clad. The illuminator is in excellent condition - there do not appear to be any broken fibers - transmission is uniform all the way around the output ring. There are no manufacturer's markings.
