Abstract

An arrangement for distributing radiation, the arrangement comprising a radiation source (1) and a plate-like distributor element (3), positioned in the passage of a radiation beam (2) produced by the radiation source, for distributing the radiation. According to the invention, the radiation beam (2) is oriented at a slight angle to the plane (4) of the distributor element, and the distributor element comprises a plate-like body portion (5) made from a transparent material and reflective surfaces (7) arranged stepwise one after the other and side by side on the body portion (5) in the direction of the radiation beam (2) and at an angle to the plane (4) of the distributor element for dividing the radiation beam into substantially mutually parallel sub-beams (8) in a direction that differs from the direction of the radiation beam.
