Light source connector with splayed optical fibre bundle

摘要

A light guide 1 for a borescope or endoscope has an optical fibre bundle 6 terminating in a light source connector 3. The light source may have a lamp 26 and reflector 27 in axial alignment with the connector and providing a convergent light beam with maximum intensity in a non-axial direction. The connector is provided with a terminal assembly 16 in which end portions 15 of the fibres are splayed so as to lie within an annular space 14 in which they are constrained to lie at a predetermined angle relative to the axis.
