Robot laser beam manipulator
An appts. for manipulating a laser beam (F) in a given direction (X1), for use in robot systems for cutting or welding. A flat mirror (4), whose position is adjustable (X4,X6) deflects the laser' beam through a given angle alpha away from X1. A second parabolic mirror (8) deflects the beam through a second angle beta towards X1. A third flat mirror (12) whose position is adjustable (X12, X14) deflects the beam through a given angle gamma to achieve alignment with X1. The interaction of the laser beam with a surface under treatment (P) produces fumes which are removed by a gas flow.
