Lasers and laser-related equipment. Test methods for laser beam widths, divergence angles and beam propagation ratios - Stigmatic and simple astigmatic beams Ingestion-build-103253 The test according to BS1 Scope This part of ISO 11146 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This part of ISO 11146 is only applicable for stigmatic and simple astigmatic beams. If the type of the beam is unknown, and for general astigmatic beams, ISO 11146 2 should be applied.
