ABSTRACT:
The present invention provides an apparatus and method for projecting a reference plane. The invention features emitting a light beam, splitting the light bean into two or more resulting beams, and converting the resulting beams into respective projected lines. The projected lines can be used to indicate a reference plane that substantially spans greater than 90 degrees from a reference point. The invention also features at least two lasers configured and arranged to emit a laser beam. An optical element corresponds to each laser to convert each laser beam into an output line that are projected to form only a single reference plane.
