BEAM TRANSFORMATION ELEMENT, DEVICE FOR TRANSFORMING ELECTROMAGNETIC RADIATION, METHOD FOR PRODUCING A BEAM TRANSFORMATION ELEMENT, AND METHOD FOR TRANSFORMING AN ELECTROMAGNETIC EMISSION

摘要

A beam transformation element (1) for transforming electromagnetic radiation, in particular laser radiation, comprising an irradiation surface (2) and an emission surface (8). The irradiation surface (2) comprises at least four cylindrical segments (3), wherein each cylindrical segment (3) has at least two adjacent segments. A cylinder longitudinal axis (4) of a first cylindrical segment (3) is not parallel to each cylinder longitudinal axis (4) of an adjacent cylindrical segment (3).
