Abstract
Systems, methods, and devices for providing Köhler illumination for inspection, under a microscope, of end connectors of fiber optic cables. In one aspect, a microscopy system provides Köhler illumination where a numerical aperture of the illumination (NA) is greater than a numerical aperture of imaging (NA). In another aspect, a reflected light microscopy system includes an array of light sources which illuminate a diffuser, which, in turn, projects the diffused light to reflect off of a beamsplitter and through an objective/condenser upon the end connector. In yet another aspect, the array of light sources may provide different light patterns to illuminate the end connector, and each light pattern may correspond to a different type of radiused end connector.
