Scanner window

摘要

A scanner window through which a laser beam is projected to define a scanning pattern comprises a substrate formed of light transmissive material which allows the laser beam to project through a light transmissive hard material layer deposited onto the substrate, and a light transmissive lubricous coating deposited onto the hard material resulting in the scanner window having improved resistance to abrasive wear. The present invention is also directed to a method of producing such a scanner window. The present method may incorporate various deposition techniques to form a wear resistant scanner window in accordance with the present invention.
