Abstract:
A laser level comprising a first laser module and a second laser module, each comprising a laser diode and an optical unit, a holder arranging the first laser module and the second laser module in a fixed relative position, and a housing, in which the holder is suspended with a gimbal or ball joint. Each optical unit comprises a collimating lens arranged along the beam path following the laser diode, and configured for collimating a beam emitted by the laser diode; a pair of partially transmitting mirrors, each arranged along the beam path following the collimating lens, and configured for laterally reflecting less than half of the collimated beam in terms of the beam cross-section, and in terms of the beam intensity; and a cylindrical lens arranged along the beam path following the pair of partially transmitting mirrors, and configured for shaping the collimated beam into a fan beam.
