M2 Monitors

M² Monitors for Laser Beam Quality Determination

  • Automated measurement for rapid evaluation
  • LPM200: M² Monitor ISO for evaluation according to EN-ISO standard
  • Squarelux Monitor NIR/VIS/355 for beam quality determination from a single pulse
  • Integration into production processes via TCP/IP
  • CCD based sensor with high linearity
  • Calibrated ex works for highest precision


Our M² Monitors are designed for an exact determination of the M² value of laser beams. With their high evaluation accuracy they are being employed in industry and laser production and control. the remote control option allows for a simple integration into production processes. The M² Monitors consist of CCD based detectors in combination with either the optimized anlysis software "Squarelux" or the Beamlux II advanced beam profiling software with M² tool. All relevant laser beam parameters such as M², divergence, waist diameter and waist position are displayed.

Optional accessories enable the analysis of laser beams with large diameters and high powers.

The M² Monitor ISO is a compact detector system for a rapid, automated determination of the laser beam quality. Mechanical and software-based adjustment tools allow for a quick set-up and start of measurements. Within 30 seconds a result will be available.

The M² Monitor NIR/VIS detector system allows a measurement according to the current EN-ISO 11146 standard. With the help of the extensive set of optional accessories a large variety of lasers operating in the UV, VIS and NIR wavelength ranges can be analyzed.
