M2-Beam Propagation Analyzers

Not all commercial M² measuring instruments conform to the ISO 11146 method of employing a fixed position lens and moving detector. Instead, some manufacturers use a fixed position detector and a moving lens. If the laser beam is diverging or converging within the travel range of a moving lens, the reported M² value and other results can be significantly compromised. Spiricon's M²-200s Beam Propagation Analyzer is fully ISO 11146 compliant.
