An optical device has a plurality of optical elements lined up in a row laterally. The optical elements in each case have a light entry surface, a light exit surface, and an associated optical axis. The light entry surfaces are in each case formed convexly in the manner of a lens in a central region surrounding the optical axis. The central region is in each case surrounded by an annular reflector, which is preferably composed of a plurality of individual reflectors.
