Overview
ISO 15367-1:2003 establishes standard test methods and terminology for determining the shape of a laser beam wavefront. Published by the International Organization for Standardization (ISO), this standard is primarily focused on the measurement and analysis of the spatial phase distribution of a laser beam across a plane that is nearly perpendicular to the direction of propagation. By specifying rigorous requirements for measuring, analyzing, and reporting quantitative wavefront parameters and their uncertainties, ISO 15367-1:2003 helps ensure consistent quality and comparability in the characterization of diverse laser beam types, including those from both continuous wave and pulsed lasers.
