MS-1780 Laser M2 Measuring System

M²-1780

Schnelle M2 Mess-System mit Silizium Firewire Kamera

Das ModeScan Modell 1780 ist ein Gerät zur Strahlprofilmessung, das die Qualitätskennzahl M2 und alle verbundenen ISO 11146 Parameter sofort in Echtzeit bei Bildraten von über 20 Hz misst. Die von Photon Inc. patentierte Messtechnologie nutzt 10 reflektierende Oberflächen, um mit einer Modell 2512 CCD Array Kamera gleichzeitige Bilder des sich ausbreitenden Strahls zu machen.

FAQ

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.

What is the advantage to using the 1780?

The 1780 is designed to provide an instant M2 value with no moving parts, making it possible to get an M2 value from a single shot of a laser, or to get instant feedback on M2 values while tuning a laser. This makes the 1780 great for applications where you need to quickly verify the performance of similar lasers.

There seems to be a lot of play in the mounting of my unit. What can I do?

Since the gimbal mount is spring loaded, we recommend that the adjustment screws are set to a central position to apply adequate tension on the springs and make minor adjustment in the alignment process.

Why is my camera not showing up in the list of available cameras in the Data Collection \ Camera Selection menu?

The IEEE 1394 adapter card driver is likely not set properly to one that includes the name Basler. You will need to update the driver for the IEEE 1394 adapter card that the camera is connected to manually. Go to the Windows Device Manager, right click on the adapter card driver, select "Update Driver Software", then "Browse my computer for driver software", then "Let me pick from a list of device drivers on my computer". At this point, select a driver from the list that includes Basler in the name. Complete the wizard and then disconnect the cable from the back of the camera for 5 seconds, then reconnect it. Watch for a Basler category to show up in the Windows Device Manager at the top of the list. When it does, you should be able to open the FireWire BeamPro software again and select your camera from the list.

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.

Introduction to the operation of the Photon ModeScan 1780 Instant M2 instrument. This instrument can measure your laser in real-time, allowing the M2 to be determined for CW, pulsed and even single shot lasers. The video includes tip to make setting up this system even easier.

Simple alignment procedure of the MS-1780 Real-Time M² Analyzer

Proper alignment of the MS-1780 is essential for its operation, and this can occasionally seem difficult to achieve. Here is a simple method for making sure the system is properly aligned to get the “first light” conditions that will allow easy fine tuning for experimental results. In order for the system to work properly the laser beam needs to enter the optical center of the aperture on the horizontal axis of the instrument. In order to be able to fine-adjust the beam it is useful to use steering mirrors to direct the beam. These can be mirrors or quartz plate front surface reflectors if Weiterlesen...
