ABSTRACT:
An articulated arm for conducting the beam of a laser to a point of utilization which moves relative to the laser. In the preferred embodiment the articulated arm is supported in a generally vertically depending manner from a stationary laser. The articulated arm terminates in a focusing clamp assembly which is positioned by an industrial robot. The articulated arm following the motions of the robot. The articulated arm comprises joints through which the laser beam is conducted and which contain mirror assemblies for changing the direction of the laser beam as it passes through each joint. A joint may include a rotary coupling member on a main body providing relative rotation of the axis of one of the incident and reflected laser beams about the axis of the other. The mirror assemblies include adjustable shim mechanisms which provide for the precision adjustment of the mirrors to secure alignment of the incident and reflected laser beam along the intersecting path segments through each joint. Each mirror is replacably mounted on its joint by means of a coolant distributor assembly disposed against the mirror and providing cooling for the mirror.
