1. A fitting tip for an inspection microscope for inspecting an angled fiber-optic connector endface inserted into a fiber-optic connector adapter, the fitting tip comprising:
a tip housing having a front end for inserting into the connector adapter opposite to the connector endface, a back end for mounting to a front portion of the inspection microscope, and an internal channel extending from the front end to the back end; and a relay lens system disposed inside the internal channel of the tip housing, wherein, when the front end of the tip housing is inserted into the connector adapter and the back end of the tip housing is mounted to the inspection microscope, the optical axis of the inspection microscope and the optical axis of the relay lens system intersect inside the internal channel of the tip housing and form a predetermined nonzero acute angle γ1; the optical axis of the relay lens system is aligned with a point on the connector endface, forming a predetermined nonzero acute angle γ2 with a normal line to the connector endface at the said point on the connector endface; the optical axis of the inspection microscope is aligned with a conjugate ray, with respect to the relay lens system, of the ray emitting from the connector endface along the said normal line to the connector endface; and the connector endface is imaged through the relay lens system on an imaging plane within a focusing adjustment range of the inspection microscope. |
