ABSTRACT:
Efficient and cost-effective generation of two co-linear laser beams or two or more intersecting beams, for the purpose of alignment as in the construction industry, takes advantage of the unequal divergence of light from a typical laser diode that produces a beam of elliptical cross section. Two roughly equal co-linear beams of light, or two or more intersecting beams, can be generated by reflecting the collimated elliptical beam from preferably two mirror surfaces oriented obliquely to the beam and so as to divide the elliptical beam in two. If one of the reflective surfaces is a beam splitter, three essentially intersecting beams can be generated. In preferred embodiments these three beams are at right angles to each other, particularly for use in construction layout.
