Lasers and laser-related equipment — Test methods for laser beam widths, divergence angles and beam propagation ratios — Part 1: Stigmatic and simple astigmatic beams
激光器和激光相关设备激光束宽度 发散角和光束传播比的测试方法 - 第1部分:柱状和简单的散光光束
This document specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This document 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.
