Abstract
A system which is preferably employed in a laser alignment instrument produces up to five orthogonal beams from a single laser diode beam. The optics take advantage of the elliptical shape of the beam from a laser diode to produce a plurality of masked, parallel collimated beams which are then reflected by combinations of 45.degree.-angled and 90.degree.-angled mirrors, some fully reflective and some partially transmissive, to produce the orthogonal beams.
