Abstract
An optical element includes first regions which reflect or transmit the light falling on the optical element. The optical element also includes second regions which are in each instance separated by a distance from a first region and which at least partially surround a first region. The second regions are designed to be at least in part electrically conductive and are electrically insulated from the first regions. The optical element includes a carrier element and at least two first regions in the form of mirror facets which are arranged on the carrier element. The second regions are arranged with a separation from the mirror facets on the carrier element and are electrically insulated against the carrier element as well as against the mirror facet. At least one mirror facet is surrounded by an electrically conductive second region.
