ABSTRACT:
A laser alignment apparatus is provided for use in positioning workpieces relative to one another and first and second spaced-apart substantially parallel reference planes. The laser alignment apparatus comprises a first projector for providing first and second reference beams of light disposed in a substantially orthogonal relationship with respect to one another. A second projector provides third and fourth reference beams of light disposed in a substantially orthogonal relationship with respect to one another. The first and second projectors are positioned relative to one another so that the first and third reference beams of light are substantially collinear with one another and the second and fourth reference beams of light are positioned substantially parallel to one another. The second and fourth reference beams of light define the first and second substantially parallel reference planes and permit the workpieces to be positioned relative to one another and the first and second parallel reference planes.
