ABSTRACT:
An improved portable field inspection microscope intended primarily for, but not in all cases limited to, use in inspecting butt ends of fiber optics cables, or other similar cylindrical objects, and including a receiver, holder and positioner adapted to receive such a butt end of a fiber optics cable, or the like, and to position same coincident with a selected butt-end-surface-viewing plane, which may also be considered as a microscope focusing plane, which lies appropriately forwardly of a microscope optical-path-defining longitudinal cylindrical inner chamber in a small portable housing and which not only carries said receiver, holder and positioner at a forward location, but intermediately carries microscope objective lens mounting apparatus and a microscope objective lens assembly for focusing on said focusing plane, and with the housing also being further rearwardly provided with microscope eyepiece lens mounting apparatus and an eyepiece lens assembly longitudinally adjustably carried for focusing on, and providing a desired degree of apparent visual image magnification of, a butt end surface of a fiber optics cable, or the like, which is being viewed and inspected while received, held, and positioned in the focusing plane. The housing is also provided with bright field illuminator apparatus and dark field illuminator apparatus and controllably operable switch and battery assembly structures for providing either bright field illumination of directly forwardly incident light and directly rearwardly reflected reverse light, or dark field illumination of annularly arranged sharply angularly directed incident light and consequent sharply angularly reflected and effectively "lost" reverse light for dark field illumination of a butt end surface positioned in the focusing plane for viewing and inspection.
