ISO 11146-1:2005 Preview
Lasers and laser-related equipment -- Test methods for laser beam widths, divergence angles and beam propagation ratios -- Part 1: Stigmatic and simple astigmatic beams
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
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.
