M²-200s Laser M² Measuring System
This camera-based M² measurement system accurately analyzes lasers with wavelengths from 266nm - 1300nm with its silicon camera. It features a compact portable design, automatic attenuation filter adjustment, ISO compliant measurements, and operates in CW or Pulsed modes which makes it ideal for comprehensive analysis of lasers of most beam diameters and powers.

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
Does the M2-200 and M2-200s internally provide all the necessary attenuation for operation with the direct laser beam?
Before allowing laser energy to enter the instrument, it is important to limit the beam intensity. Excessive laser energy may cause damage to the camera or the internal components of the M² optical train.
Typically, a CCD camera imager can be damaged at energy levels in excess of 1 mJ/cm² or at power levels greater than .15 mW/cm². Adjust these input limits downward based on the likely focused spot size resulting from your M² lens focal length. Beam splitters and/or filters may be used to attenuate the beam, but care must be used to prevent the introduction of distortions.
During an M2 measurement operation, the peak energy density that reaches the camera will change, potentially over several orders of magnitude. This is a result of the camera effectively moving from a larger unfocused spot near the lens, into and through the focus at the waist, and then out again to an unfocused spot (see Figure 21 on page 96). The optical train will automatically adjust to accommodate these changes in beam intensity, so long as you, the operator, have prudently selected the initial beam intensity. Thus, it is your responsibility to attenuate the laser sufficiently to operate within the safe dynamic range of the M²-200/200s system.Close
End of Life for M2-200 (Long Train)
Ophir-Spiricon LLC would like to thank its customers for the support of our long standing product the M2-200. In an effort to deliver state-of-the-art and high performance products we have decided to discontinue the M2-200 (Long Train) product. We have replaced it with the M2-200S (Short Train) product which offers faster M2 results in a more compact package. In an effort to allow customers to put in a last order for the M2-200 (Long Train) products we will continue to accept orders until July 1st, 2011. Our M2-200S product will continue to be available after that time.
The M2-200 will continue to be supported for repairs and calibrations through our customer service department. email@example.comClose
I want to ask about the accuracy specifications on the M2-200-BB. In the specification, it states that typical accuracy is 5%. Is this +/- 5% of the mean measurement, and is this a 1-sigma, 3-sigma, or P-P value?
The spec is given in +/-5% of the mean measurement and is a P-P value.Close
I just installed the latest M2-200s software on my new computer and I get a message stating Windows can't install the driver for the motor controller. How do I fix this?
If you install M2-200s software v4.91 on a computer that has never had M2-200s software installed on it, it only installs the motor controller driver for our new style motor controller. If you use a M2-200s that is using the old USB controller, the hardware comes up as an Unknown Device in the Windows Device Manager because only the new driver for the new controller is getting installed and not the old driver for the old controller. If you install v4.81, then it installs the old driver for the old controller. Then install v4.91 and it will have the new driver for the new controller, fixing the problem so you can use either style controller.Close

Laser beam quality cannot be determined from a single beam profile measurement. Watch a demo of the Ophir-Spiricon M2-200 beam propagation analyzer as it calculates M2 by focusing the beam with a fixed position lens of known focal length and then measuring the characteristics of the artificially created beam waist and divergence from the near field to the far field.If you can't see the video please click here
Is your laser beam optimized for your application? In this video, we explain M2, the single value that describes how your beam correlates to a true TEM00 single-mode Gaussian beam. M2 describes how well your beam is focused on a surface. Knowing your beams M2 value allows you control the success of your laser application. Learn why laser developers and manufacturers rely on M2 measurements to design and maintain the quality of their lasers, and how knowing M2 can benefit you.
