环形激光熔覆加工头内部光路为反射-透射式环形光路。如示意图所示,分别由准直单元、反射面元件、W形轴锥镜、分束棱镜组、光学平面反射板、合束棱镜组以及聚焦透镜组成。
The internal optical path of the annular laser cladding processing head is a reflection-transmission annular optical path. As shown in the diagram, it consists of a collimation unit, a reflective surface element, a W-shaped axial cone mirror, a beam splitting prism set, an optical plane reflector plate, a combined beam prism set and a focusing lens, respectively.
