Abstract: Systems, methods, and devices for inspection, under a microscope, of end connectors of fiber optic cables are provided. In one aspect, a light ring including a circular array of light sources provides darkfield illumination to an end connector being inspected under a microscope. Each of the light sources may be lit in series and the resulting shadows may be used to identify dirt on the end connector, as well as to determine whether any dirt identified on the end connector can be cleaned off. In another aspect, a light ring combined with a redirection ring (e.g., a reflector and/or refractor ring) may provide darkfield illumination. In yet another aspect, a series of images may be captured and analyzed to automatically identify dirt on the end connector, as well as to determine whether any identified dirt can be cleaned off.
