Abstract
A device for optically measuring the distance from a reflective target object is disclosed. The device includes a beam source, a detector, a beam shaping system with a transmitter lens and a receiver lens and a laser beam shaping element which can be positioned in the beam path of the laser beam. The laser beam shaping element is embodied as a transmission aperture system with at least one transmission aperture, where at least one transmission aperture creates a partial beam and the partial beam widens to one or more beam angles which are no smaller than a minimum critical angle of 1.0 mrad.
