Abstract
A laser alignment apparatus is provided for generating a plurality of mutually perpendicular laser beams. The apparatus further includes rotatable beam diverters selectively hingedly moveable into or out of positions for diverting one of the laser beams. The beam diverters may be rotated about an axis coincident with the associated laser beam for sweeping laser planes. The laser planes swept by the respected beam diverters are mutually perpendicular to one another, and each laser plane is parallel to the other beams generated by the apparatus.
