Abstract
A device for deflection of a light beam formed of a light-permeable deflection prism extending in a direction of a rotational axis. The prism has a light entry face, a reflection face proceeding obliquely thereto and a light exit face, and is further formed of a carrier prism joined to the deflection prism at the reflection face. The carrier prism supplements the deflection prism to essentially form a cuboid unit that is seated rotatably around an optical axis that resides perpendicularly relative to the light entry face of the deflection prism. For producing a unit designed rotationally symmetrical relative to the optical axis at least in regions, the optically unused edges and corners of the cuboid unit are rounded. Spherical caps are attached to at least two of the unused outside surfaces of the unit, these spherical caps supplementing the unit to form a spherical outside contour at least in regions.
