Coated Glass Inspection

Dr. Schenk GlassInspect for caoted glass

Coated glass has become increasingly important for a growing number of high tech applications, such as TCO or Molybdenum and antireflective coatings for the PV industry, ITO coatings for display glass or Low-E coating in the architectural and automotive industry.

These materials are applied as coatings thanks to their physical characteristics e.g. electrical conductivity and high transparency and their ability to partially reflect infrared and ultraviolet rays while allowing visible light to pass. Furthermore, some of these coatings offer superior hardness and durability and therefore make ideal cover material for sensitive layers.

GlassInspect detects defects and irregularities that occur in coating layers and on the glass substrate while being processed. The innovative optical set-up and its image processing and visualization software have been adapted to the specific requirements of coated glass.
