NanoModeScan M² Measuring System
This scanning slit M² measurement system accurately analyzes lasers with wavelengths from UV to Far Infrared with its silicon, germanium, or pyroelectric head. It features a compact portable design, immediate results, ISO compliant measurements, and operates in CW or kHz Pulsed modes which makes it ideal for comprehensive analysis of lasers of most wavelengths.

When in the laser life cycle is the M2 measurement the most important?
M² measurement is important if the stability of your laser is important to your process. Taking M² measurements on a frequent basis allows you to see if your laser is stable from time to time. If the results of the M² measurement fluctuate and a noticeable change happens over time, this could help identify problems with consistency in the laser and help prevent negative results to your process where the laser is being utilized.Close
Why doesn’t the NanoModeScan “ModeScan Configuration” program remember the COM setting?
It has been observed that on networked computers with security, that in order to keep the COM setting in the NanoModeScan “ModeScan Configuration” program persistent, it needs to be launched with a right-mouse-key-click and select “Run as administrator” in order for it to work OK.Close
Can you change the rotation frequency of the NanoModeScan?
Why does my profile work well while running the NanoScan software but the profile diminishes in the NanoModeScan software?
The NanoScan software starts at a rotation frequency of 10 Hz while the NanoModeScan starts at a rotation frequency of 20 Hz. At the frequency of 20 Hz, less signal is getting to the detector because of the speed of the slit passing over the detector. This makes it look like you are not getting as strong of signal. The NanoModeScan starts at this higher rotation frequency because the NanoScan is meant to pass through the focus of the beam, making the power or energy density higher. This higher power or energy density can over-saturate the NanoScan at 10 Hz.Close
Can the NanoModeScan software export 2D/3D images?
The 2D and 3D profiles are NOT exportable.The NanoScan and NanoModeScan's 2D and 3D images are not actual 2D and 3D profiles of the beam. They are mathematically generated profiles calculated from the 1D profile information. Thus they are not completely accurate profiles.Close
Can a NanoModeScan unit be triggered to capture a pulsed source?
The NanoScan can capture a high repitition rate pulsed laser source but it can not be triggered from the laser itself. To capture a pulsed source on the NanoScan you must choose one of the pulsed settings under the Capture tab. The laser pulse rate must also be greater than 100 kHz.
Why can my M2 unit have an M2 measurement less than 1?
There are two common occurrences when M² results are less than 1. The first and most common of these results from 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 is due to nominal accuracy tolerances. These are normal and expected. With a 5% M² tolerance results from ~.95 to ~1.05 are possible. Averaging runs will normally return a mean value to something > 1, but not always.
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 NanoModeScan software make computations and report results as the input settings and the beam samples dictate. This is done to provide useful information to the operator rather than to try and conceal the issue.Close

Is your laser's beam profile shaped correctly for your application?
This video teaches the fundamentals of laser beam profiles and discusses the benefits of profiling your laser beam.
Several case studies are presented showing before and after laser beam profiles.
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.
