Abstract
A fitting tip of fiber-optic connector endface inspection microscope for inspecting angled connector endfaces includes a relay lens fixed inside its internal channel and is designed such that when it is received in an intended connector adapter and mounted to the inspection microscope, the normal line to the connector endface forms an acute angle γ with the optical axis of the relay lens; the ray exiting from the relay lens and conjugate to the ray along the normal line is aligned with the optical axis of the inspection microscope; and as a result the connector endface is imaged on an imaging plane within the focusing adjustment range of the inspection microscope. The best image of the connector endface is obtained when the angle γ is half of the inclined angle of the angled connector endface.
