ABSTRACT:
Aligning and testing alignment of optical elements in a laser beam delivery system using non-visible radiation. An alignment mirror replaces a beam redirection mirror and includes a fluorescing substrate and a dielectric coating on an incident face of the fluorescing substrate that reflects a major part of an incident laser beam along a next leg of the beam path and transmits a part of the beam into the fluorescing substrate, which is transmissive to visible radiation and fluoresces when irradiated by the beam to emit a visible light image from a back face of the alignment mirror. An alignment target on the back face indicates a preferred point of incidence of the beam on the alignment mirror for a desired alignment of the at least one laser beam. A lens may be tested and the properties of the lens determined by use of a fluorescing target plate.
