A sighting device is provided which is used to produce an optically perceptible target marking on an object. The sighting device includes one or more light sources for providing at least two sighting rays. A precision target marking is produced in such a manner that each of the sighting rays is directed onto a respective optical component enabling both of the sighting rays to be split on a respective illumination plane in such a manner that at least two illumination planes intersect at an angle. The point of intersection forms the target marking. A measuring, working and/or operating device is optionally provided which can be used with or without contact and which interacts with an object of any type at a predetermined target location. The target location can be detected by means of the inventive sighting device.
