Lenses are precision components, where the smallest deviation from the target geometry results in a change in quality. Quality control can only accompany production if a high-accuracy measuring centre such as the Leitz PMM-Xi from Hexagon Manufacturing Intelligence is used, particularly with large lenses with a diameter greater than 200 mm. The combination of tactile measurement with the HP-S-X5 HD for alignment and the PRECITEC LR optical sensor for quality assessment of the lens geometry, is made possible by the SENMATION sensor interface in automated measurement procedures.
