System for delivering the output from an optical fibre

摘要

A termination for an optical fiber is disclosed, including an end cap optically connected to a delivery end of the fiber and tapering its towards its proximal end so as to expand the signal beam output by the fiber, a capillary having a bore mounted so that the end cap and an end portion of the delivery fiber are mounted within the bore, the capillary having an end which is angled so as to reflect undesired radiation within the capillary away from the fiber, and a cladding mode stripper arranged upstream of the delivery end.
