激光材料加工中最重要的决定之一是选择适合于加工任务的聚焦光学件。它必须能正确地使原始激光束成形 ,并将其集聚到工件上。应采取希望的、可靠的聚焦方式 ,以便高效加工和获得高质量结果。多数金属板切割系统使用透镜传输 CO2 激光功率 ,并将其紧密聚焦在工件上产生狭窄的切 One of the most important decisions in laser material processing is the selection of focusing optics that are suitable for the processing task. It must be able to correctly shape the original laser beam and collect it onto the workpiece. Promising, reliable methods of focusing should be taken to efficiently process and achieve high quality results. Most sheet metal cutting systems use lenses to deliver CO2 laser power and focus it closely on the workpiece to create a narrow cut
