Grenzebach, in collaboration with Innomess, has developed a new optical method for the quality inspection of flat and bent glass based on the moire effect in physics. As is demonstrated here, the technology enables extremely accurate assessment of the optical quality of glass through the detection of defects by their refractive power. More reliable than conventional systems, the new method also requires far less maintenance than the latest laser systems.
