qBeam-2M-FW is a compact and flexible laser beam profiler with high sensitivity, high resolution and real time measurements. The user-friendly software measures critical laser beam data such as beam widths, shapes, positions, power, and intensity profiles. The software also integrates additional useful functions such as beam divergence calculations, M2 calculations and analysis.

3 ND filters (ND4/ND9/ND10) are mounted on a rotatable wheel. One can easily switch from one filter to another by rotating the wheel. It is also possible to combine these three filters to find the best attenuation.


  • Compact and flexible
