PHASE-MIXING DEVICE, LIGHTING DEVICE, AND METHOD FOR REDUCING THE SPATIAL COHERENCE OF ELECTROMAGNETIC RADIATION

摘要

The invention relates to a phase-mixing device for reducing the spatial coherence of electromagnetic radiation, comprising an optical waveguide (12), which at one end has an inlet surface (10), through which the electromagnetic radiation can be introduced into the optical waveguide (12), and which has an extension direction (14) in the region of the end, and comprising an inlet element (6), which has an optical axis (8) for imaging electromagnetic radiation onto the inlet surface (10) of the optical waveguide (12), characterized in that the optical axis (8) of the inlet element (6) includes an angle a not equal to 0° together with the extension direction (14) and/or an angle ß not equal to 90° together with the inlet surface (10) of the optical waveguide (12).
