ABSTRACT:
A side firing fiberoptic probe has an optical fiber with proximal and distal ends and the cladding is removed from its distal end portion. On the distal end of the core is a transparent reflector of generally cylindrical configuration and it is of larger diameter than and coaxial with the core. The reflector has a planar face at its opposite end which extends at an angle to the axis of the reflector and core. Extending about and sealingly engaged with the fiber distal end portion and the reflector is the cylindrical body portion of a transparent end cap. The cap has a closed end spaced from the planar face of the reflector, and it provides an atmospheric interface between the inner surface of its closed end and the planar face of the reflector and about the unclad distal end portion of the core. Light rays passing through the core fall on the planar face in a generally circular pattern and are reflected thereby at an angle of 50.degree.-90.degree. in a generally conical beam through the reflector and cap.
