Laser beam diagnostic devices have been used extensively in laboratory environments and in process development work ever since the evolution of laser technology began. However, industrial laser users have had to rely on basic instruments and measurement techniques in order to assess the state of their lasers. Recent product introductions have gone a long way in breaking the barrier between the laboratory and the shop floor. Some of these new devices are compact and low cost with simple user friendly interfaces that can be used by the average machine operator.
Some enlightened users are now looking to greater levels of beam monitoring to assist in preventive maintenance schedules, as a tool to maintain product quality and even for on-line and in-line beam monitoring applications to provide input to process control.
