P/N 203605

Automated M-squared measurement system. Comes with BEAMAGE-4M, 5 lenses, 3 ND filters, and 2 external beam-steering mirrors.

Key features


The BEAMAGE-M2 is an automated laser beam quality measurement system.

Large Apertures

The only M2 system on the market equipped with a complete set of 50mm optics. Also, the sensor is 11.3 x 11.3 mm.

Simple Alignment

Two beam-steering mirrors are included for quick and easy alignment of your laser into the system. The internal mirrors are factory-aligned and the pre-set height also simplifies the alignment.


The low-profile ingenious mechanics make it easy to fit the device on any optical table.

ISO Compliant

The calculations are fully compliant to the ISO 11146 and 13694 standards.

Fast Acquisition

Make a complete, ISO-compliant measurement in only 20 seconds with the ROI feature, and in less than a minute with full-frame acquisition.

Flexible & Intuitive Software

In the easy-to-navigate software, both automatic and manual settings are available, so data points can be added or removed even after an automatic scan is completed.
