Device for generating a Bessel light beam bundle with at least one electro-optical element

摘要

a device for the production of a described bessel lichtstrahlenbu00fcndels with at least one elektrooptischen element that has a lichtein and lichtaustrittsoberflu00e4che hasthe each of the element along a elektrooptische emerging optical axis face and in lu00e4ngserstreckung to the optical axis a elektrooptische element laterally limiting surface is provided.;the invention is characterized by the fact that flu00e4chenelektroden so trained and along the surface that are arranged in an electrical voltage to the flu00e4chenelektroden application inside the elektrooptischen element an electric field generierbar isthe optical axis of the radially oriented feldstu00e4rkeverlauf linearly proportional with the radial distance from the optical axis changes.
