Abstract

An alignment device includes an incoherent light source, a first convex lens, a mirror rod, and a second convex lens. The incoherent light source emits incoherent light that is received by the first convex lens that produces a low divergence light beam. The low divergence light beam is directed to the mirror rod that reflects the light beam to the second convex lens that focuses the light beam to a convergent light beam.
