ISO 11146-1:2005 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams.
ISO 11146-1:2005 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 is applicable.
