Abstract
An apparatus for deflecting an optical beam is designed as a prism and has an entry face as well as two reflection faces and two exit faces. The prism is essentially symmetrically constructed with reference to a rotational axis. The entry face is oriented essentially perpendicularly relative to the rotational axis. Those sides of the prism facing away from the entry face are designed as reflection faces having an inclination relative to the rotational axis, these reflection faces adjoining one another in the region of the rotational axis. Those sides of the prism facing away from the rotational axis are designed as exit faces which adjoin the entry face and the respective reflection face and, proceeding from the entry face, extend with increasing distance from the rotational axis.
