FAQ

My laptop will not connect to the BeamWatch while connected to its docking station.

Many laptops disable the GigE port on the computer when docked. You can try the port on the docking station itself or use the GigE to USB adapter that came with the unit.

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 service@us.ophiropt.com with an explanation of your problem.

When hooking up the purge line to the BeamWatch, what line-pressure should I allow to enter the unit?

The input pressure for the BeamWatch can range from 20 to 50 PSI. For optimal performance the pressure for operation should be around 40 PSI at 10 LPM.

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.

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.

Focus shift monitoring of high power laser Focus shift monitoring of high power laser Focus shift monitoring of high power laser

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.

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.

Attenuation-Induced Error Due to Thermal Lensing in Beam Measurement

The need to profile lasers with powers in the 10mW to 1W range are becoming more common. Many of these lasers are in the visible spectrum, allowing them to be measured with CCD and CMOS camera systems. As with any laser that is being measured with a camera array, the beam needs to be attenuated, but there are some cautions to be observed. These beams are not so powerful that they will damage or destroy typical absorptive filters. In fact, it is possible to stack up a sufficient optical density to reduce the power of a 1W laser to the nW levels that will not saturate the detector. Weiterlesen...

The Challenge of Focus Shift in High Power Laser Material Processing

High-power industrial lasers are valuable tools in material processing. Maintaining them at peak performance and optimizing the processes for which they are used will maximize throughput and minimize downtime. Periodic measurement and longterm monitoring of key laser variables, including laser output power, focused spot size, and focus spot temporal location provide the data you need to increase accuracy and optimize your process... Weiterlesen...

Laser Measurements in Materials Processing: How and When They Absolutely, Positively Must Be Made

19th century British physicist and engineer William Thomson, 1st Baron Kelvin, was the first to say, “If you can’t measure it, you can’t improve it.” When applying this principle to improving laser-based processes, there are a variety of parameters that must be measured. Given the continuously rising power of laser systems in material processing, the requirements for measurement systems are more challenging than ever. Which technologies are available to measure high-power lasers? How often should they be measured? What measurements should be tracked? When this data is collected, what should be done with it? Weiterlesen...

White Paper – Image Of Laser From Rayleigh Scattering Directly Correlated To Beam Waist Measurements Of High-Power Lasers

AbstractThe discovery of Rayleigh Scattering by 3rd Baron Rayleigh, John William Strutt, served an explanation of why the sky is blue during the daytime and different hues of orange, pink, and purple in the early morning hours and at dusk. But it was only recently that this phenomenon has been applied to the measurement of high-powered lasers. Only through the measurement of the laser source and laser system can the user of the laser fully understand its performance and then start to control the processes in which they are used. Key laser parameters which ensure a successful process include Weiterlesen...
