The system contains a purge chamber 12, 112. A substantially optically transparent wall 14, 114 is formed along the purge chamber 12, 112. A laser projector 16, 116 is mounted within the purge chamber 12, 112. The laser projector 16, 116 is positioned to project a laser beam through the substantially optically transparent wall 14, 114. The system may be used to project images onto objects to assist in manufacturing processes.
