摘要: The invention relates to a device for reducing the coherence of a beam of light, especially a laser beam, for illuminating an image surface or a sample. According to the invention, said device comprises a beam splitter (2) whereon an incident beam (1) is split into two orthogonal partial beams (4,6), and two reflecting elements whereof at least one is embodied in the form of a reversing prism (7). One partial beam (4,6) is respectively directed at a reflecting element and is reflected therefrom back to the beam splitter (2). The reflected elements are positioned at various distances from the beam splitter (2) such that the partial beams (4,6) pass once more through the beam splitter (2) in an opposite direction and are combined to form an outgoing beam (8) wherein the coherence is reduced.

摘要: The invention relates to an array for reducing the coherence of a coherent radiation beam (6), wherein a reflector (1) defining an inner space is provided with a diffusely reflecting inner surface (4), wherein said reflector (1) has an inlet hole (2) through which the radiation beam (6) can be injected into the inner space, in addition to an outlet hole (3) through which the rays of the radiation beam (6) can come out after at least one reflection on the inner surface (4).
