A system to produce orthogonal beams includes a laser diode operating in
conjunction with a collimating lens, with or without an aperture, and a
simple compact optic. At least one collimated beam is directed toward an
optic comprised of components that are bonded together. Beams are
reflected from at least one optical components at right angles to produce
a plumb beam. Additionally, a beam is reflected from the optic at a right
angle, as well as transmitted through the optic, to produce square and
level beams. All beams are orthogonal to each other, have relatively
equal power, and are aligned and oriented so as to appear to be
originating from a coincident point. An optional orthogonal beam may be
produced. An optic in the shape of a cuboid comprised of six small
components is also disclosed.
