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.
What is the best beam width measurement method?
The answer depends on what information is wanted from the beam width.
- The most representative measurement of a beam width in determining how the beam will propagate is the Second Moment measurement. However, the Second Moment measurement can have problems if there is diffraction in the beam before measurement, which puts a significant amount of energy in the wings. This energy may diverge faster than the rest of the beam, and if it is included in the measurement, it will give a beam width much wider than reality. However, an aperture can be used to limit the beam width measurement to energy inside these diffraction rings.
- A second very good measurement of beam width is the software equivalent knife-edge measurement. This measurement is less sensitive to diffraction in the wings of the beam, although it will give a beam width measurement which is weighted by energy out in the wings. It is less sensitive to noise.
- Sometimes the most important information is not the beam propagation characteristics, but how much energy is near the peak of the beam. In this case, a percent of peak beam width measurement would be more useful.
The calibration date on my M2 system has expired. What do I need to do to get it re-calibrated?
After numerous requests for re-calibration of M2 systems, in 2008 Ophir-Spiricon started a recalibration program for its M2 systems. This program allows the equipment to be sent back to the factory to be inspected, lubricated and re-calibrated. This enables customers to comply with their ISO regulations. Please click the below link to be directed to a section of our web site where you can request an RMA to return your equipment for re-calibration.
I've damaged the ND filters that came with my camera. Can I order replacements?
Yes, please contact our Service Department and they can help you with part numbers for the filters you need. Service@us.ophitopt.comClose
It has been suggested that if the M² results are computed to be < 1 we should display a 1 as the answer. However the algorithms in the M²-200/200s software make computations and report results as the input settings and the beam samples dictate. This is done so as to provide useful information to the operator rather than to try and conceal something. There are two common occurrences when M² results are less than 1.
The first and most common of these have to do with the operator entering the wrong wavelength value. In this case the results are often well below 1, in the .8-.9 range. The second most common cause for results <1 is due to nominal accuracy tolerances. These are normal and expected. With a 5% M² tolerance results from ~.95 to ~1.05 are very possible. Averaging runs will normally return a mean value to something > than 1, but not always.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.If you can't see the video please click here
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.If you can't see the video please click here
