<p>An optical fibre assembly (10) for transmitting high energy laser radiation comprises a tubular moulded plastics handle (1) having a tubular metallic termination (2) for engagement with a laser radiation source. The other end of handle (1) is connected by a heat shrunk plastics sleeve (6) to a length of plastics tubing (4) the distal end of which incorporates an end formation (5) and a single plastics coated glass cored optical fibre (3) extends through the interior of termination (2), handle (1), plastics tube (4) and termination (5). The assembly (10) can be coupled to a laser source by sliding the handle (1) into socket (41) so termination (2) abuts end stop (42) and is held there by spring loaded detent (43). End stop (42) is a fixed distance from focussing lens (45) so optical axis is aligned with longitudinal axis of the socket. The socket is fixed to the laser source via flange (41A) which has X, Y adjustment (41B) to align laser beam with optical axis of the assembly. <IMAGE></p> |
