Ophir Photonics (North Logan, UT) announced the newest version of BeamWatch™, a non-contact, focus spot size and position monitor for very high power YAG and fiber lasers used in material processing applications. Because there is no contact with the laser beam, the system has no power restriction and has been successfully tested on high power lasers up to 100kW.
BeamWatch monitors high power YAG, disc, fiber and diode lasers in the 980-1080nm range. The system takes measurements of the beam at frequent intervals without having to shut down the process or remove extensive tooling and fixtures. BeamWatch measures focal spot location at 60ms intervals to indicate whether focal spot shifts are occurring during critical start-up moments.
The system can be set up to compare initial process validation measurements and can be run in automated pass/fail mode. An Automation Server can be implemented using Visual Basic for Applications (VBA), C/C++, or an ActiveX application such as Microsoft® Excel, Microsoft Word, or National Instruments Lab-VIEW®
