A device ( 1 ) for generating and projecting light marks (MP, ML) in which projection optics (P) have a cylindrical lens (Z). The cylindrical lens (Z) can be irradiated by a light beam bundle (L 2 ) such that a central beam bundle (L 2 Z) radiates completely through a cylinder portion area (A) and at least one marginal beam bundle (L 2 R) travels directly past the edge of the outer surface of the cylinder portion area (ZA). A light mark (ML) in the shape of a line is projected by the central beam bundle (L 2 Z), while a light mark (MP) in the shape of a point is projected through the marginal beam bundle (L 2 R).
