Vorrichtung zum beruehrungslosen Messen des Abstands von einem Objekt

Device for the non-contact measurement of the distance (A) to an object (10), by means of an optical device which focusses a measuring beam (11) consisting of a light beam, in particular a laser beam, onto the measuring point (12) of the object (10), having a detector (25) receiving reflected light (13) from the measuring point (12) in order to detect the focal point deviation from the surface of the object (10), in particular having a measuring lens (2) focussing the reflector light (13) through a diaphragm (14) onto a light-sensitive sensor (15) and an evaluation unit (17) receiving sensor signals. In order to cause the greatest possible precision of distance measurement between a focussing mechanism and a working light source, the device is designed so that the measuring beam (11) is focussed onto a workpiece acting as a measuring object (10) by including the focussing mechanism (18) of a working laser and that the measuring beam (11) is arranged along the same axis or along a paral lel axis to the working beam (19).
