M², or Beam Propagation Ratio, is a value that indicates how close a laser id to being a single mode TEM₀₀ beam. This in turn relates to how small a spot a laser can be focused.

 What is M²?

The Spiricon M²–200 Beam Propagation Analyzer is the only ISI 11146 compliant on the market. It will automatically measure your beam focusability in as little as 3 minutes. Manual version is available.

 Automatically or Manually measure laser beam quality

The M²-200S maintains or leadership position providing the only ISO compliant system for all reported measurements. The high speed optical train uses a fixed position lens, and automatically translates the image on the camera from the near field to the far field. Manual mode is available.
