BeamWatch™ uses innovative technology to measure very high-power fiber lasers and YAG. By not interrupting the beam while still delivering instantaneous measurements, users can monitor beam characteristics at regular intervals without having to shut down the operation or remove tools and fixtures.
Furthermore, users can now assess a focal spot position at millisecond intervals and determine whether there is a focal spot movement during important start-up times.

The BeamWatch® industrial beam profiling device provides data that has never been observed or quantified before, even by laser users who have worked with high-power lasers for many years.
The laser engineer can determine how variations in power density affect process quality by dynamically measuring the beam waist location. For example, information on the laser's impact on the quality and uniformity of laser welds, cuts, and drilled holes is now available.
