A safety laser scanner for securing the surroundings of at least one object has a first safety laser scanner with which a first defined reference target is associated and a second safety laser scanner with which a second defined reference target is associated. Each safety laser scanner includes: a light transmitter; a light deflection unit for a periodic deflection of the light into a scanning plane; a receiver for providing received signals in dependence on light remitted at articles present in the field of vision of the scanner; and an evaluation unit for evaluating the received signals with respect to the angle and the distance of the article and for providing a safety signal. Furthermore, the scanning planes of both scanners are aligned in a coplanar manner and the first scanner forms the second reference target and the second scanner forms the first reference target.
