Abstract: There is provided an adapter tip to be employed with an optical-fiber connector-endface inspection microscope device and an optical-fiber connector endface inspection microscope system suitable for imaging two non-parallel APC optical-fiber endfaces of a duplex (i.e., APC trans-duplex) optical-fiber connector. Because the two optical-fiber endfaces of an APC trans-duplex connector are angled-polished (APC) in different directions (non-parallel), inspection light reflected on the two endfaces take diverging pathways. A single-fiber or multi-fiber inspection microscope therefore cannot allow inspection of both optical-fiber endfaces at once. The proposed adapter tip or microscope system comprises relay optics defining two imaging paths (one for each optical-fiber endface), wherein each imaging path comprises at least one optical component (e.g., an optical prism) used to deviate inspection light from each endface towards the optical axis of the objective lens, such that both endfaces may be imaged within the field of view of the inspection microscope.

Abstract: There is provided an adapter tip to be employed with an optical-fiber connector endface inspection microscope and an optical-fiber connector endface inspection microscope system suitable for imaging the optical-fiber endface of an angled-polished optical-fiber connector deeply recessed within a connector adapter. The adapter tip or microscope system comprises a relay optical system comprising a Rhomboid prism. The Rhomboid prism being disposed so as to receive light reflected from said optical-fiber endface during inspection and laterally shift the light beam reflected from the angled-polished optical-fiber endface.
