ROTATIONAL CONSTRUCTIONAL LASER

摘要

A rotational constructional laser including a light source for emitting a laser beam (L) and located in the laser housing, a laser beam motor-driven deflection device located in a housing unit secured to and at least partiall y projecting beyond the laser housing and having a least one beam hole for the laser beam, a device for tilting a rotational axis of the deflection device a detection device for detecting a return laser beam (R) reflected from a display mark and entering the housing unit through the at least one beam hole, an evaluation and control unit connected with the detection device and controlling operation of the tilting device, and an automatically actuatable device for adjusting an axial position of the deflection device with respect to initial axial position of the deflection device in accordance with the detection data obtained in the detection device.
