Beam Spread Ratio The beam spread ratio is a parameter that quantifies the extent of beam divergence or expansion relative to the initial beam diameter. It provides a measure of how much the laser beam spreads out as it propagates away from the source. Understanding the beam spread ratio helps operators predict and control the beam's coverage area, intensity distribution, and depth of material removal during engraving processes. By optimizing the beam spread ratio, operators ensure consistent and reliable engraving results across various materials and surface geometries, enhancing engraving efficiency and quality.
