A laser beam (2) is split by a wedge-shaped prism (4) with two or more sides (5, 6), collimated through a convergent lens (8) and passed through a transparent ball to focus on points (10, 11) on a plastic material, e.g. for welding. The beams can be moved by passing them though alternating diverting prism (19) to produce zigzag lines (17, 18). An independent claim is also included for an arrangement for heating plastics with a laser incorporating such wedge-shaped beam-splitting arrangements and a movable transparent ball to guide the beams and to press the materials to be welded against each other. |
