Lasers and laser-related equipment - Test methods for laser beam widths, divergence angles and beam propagation ratios - Part 2: General astigmatic beams
This standard specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This part of the standard is applicable to general astigmatic beams or unknown types of beams. For stigmatic and simple astigmatic beams ISO 11146-1 is applicable.
