- BeamWatchBeamWatch is a simple means of evaluating the laser performance at periodic intervals. It compares key laser performance parameters against preset ranges to provide Go/No-Go readouts so that the laser user knows when to take corrective actions.
My laptop will not connect to the BeamWatch while connected to its docking station.
My beam measurement seems different than I expected. What can I do to check the measurement?
The measurement accuracy has been improved in recent versions of the software. It was discovered that a gain floor needed to be established to prevent early saturation of the camera. This gain floor was implimented in BeamWatch version 2.2.0. Please check your software version. The newest verions of the software from this link. If you are still having problems, please send a data file to our Service Group for analysis at firstname.lastname@example.org with an explanation of your problem.Close
When hooking up the purge line to the BeamWatch, what line-pressure should I allow to enter the unit?
With the BeamWatch how can I get readings void of comets or streaks in my image?
It is recommended that you supply clean, dry, filtered air or nitrogen to the BeamWatch. Also allowing the unit to purge for a time and adjusting the pressure with the inlet valve will help to eliminate most, if not all of the comets and streaks in the image. For more information please consult the manual under section 2.4. It is important to keep the dust covers over the openings of the BeamWatch in place until the purge air is flowing in order to prevent dust particle contamination prior to operation.Close
Is a beam dump included or needed to operate the BeamWatch?
A beam dump is not included in the purchase of the BeamWatch. We recommend using a beam dump or equivalent product to protect people and equipment. When using a beam dump or a power sensor, it is not recommended to have the beam dump or power sensor too close to the exit aperture of the unit. Doing so will elevate the background which can impact the accuracy of the results.
A few options for beam dumps can be found here.
If you are interested in obtaining power meter readings at the same time, we would recommend some of our high power sensors that can be found here.Close
BeamWatch™ utilizes disruptive technology to measure very high power YAG and fiber lasers. By not intercepting the beam and yet providing instantaneous measurements, you can now monitor the beam characteristic at frequent intervals without having to shut down the process or remove tooling and fixtures to get access. In addition, you can now measure focal spot location at millisecond intervals and know if there is any focal spot shift during those critical start-up moments.
Modern production facilities must constantly increase throughput, at less cost, with less scrap, and with minimum downtime. In this video overview, you will learn how application of new, advanced technology in measurement devices, can help both designers and users of industrial laser systems to optimize and control their processes, so they can accomplish these goals and achieve consistently good results – both in quality and quantity.

The BeamWatch® industrial beam profiling system provides data that has never been seen or measured, even to laser users that have been working with high-power lasers for years. Through the dynamic measurement of beam waist location, the laser engineer can know how changes in power density affect the quality the process. For example, data is now available about the laser’s effect on the quality and consistency of laser welds, cuts, and holes drilled.
Ophir-Spiricon has been honored with a 2015 Utah Innovation Award from the Utah Technology Council for BeamWatch®, the industry's first non-contact, focus spot size and position monitor for very high power YAG, fiber, and diode lasers. Rachael Tyler, mechanical engineer with Ophir-Spiricon explains BeamWatch in this video.
