Laminated safety glass, solar panels, flat screens and smartphone displays comprise multiple layers of different transparent materials. Measuring the exact thickness of these individual layers, as well as any air gaps between these layers, during production is a critical but physically complex process and a challenge for measurement technology. In the manufacture of multi-layer curved glass for aircraft, automotive and architectural applications, precise thickness measurement of the individual layers, and combined overall laminate, are required. If the curvature of the different layers is not precise, when the layers are sandwiched together there could be a risk of stress points developing within the glass, which in turn could lead to defects or delamination of the glass. For quality inspection and process control of manufactured transparent multi-layer materials, Micro-Epsilon has developed a range of confocal chromatic displacement sensors and controllers, which together, provide multi-peak measurement capabilities for multi-layered glass. The result is improved product quality and increased production yields for manufacturers.
