The Standard for Float Glass Inspection – Now Even Better!

Non-Stop Highest Quality in Float Glass Production using Second-Generation Camera-Based In-Line Inspection

Today, when inspecting float glass, it is critical to not only detect the smallest inclusions and point defects, but to also be able to find optical distortions that are very difficult to recognize.

Based on the patented moire technology, now there is an in-line inspection system available making it possible to control quality one hundred percent of the time and that is capable of providing reproducible inspection results. The inspection system contributes significantly to optimizing the production process and in its latest version it has been improved even more.

Inclusions, such as stones and bubbles, scratches as well as tin defects are simply unacceptable for float glass applications in the automotive or mirror industry. Even optical distortions can be very annoying. Most image processing systems that are typically used in the market are able to detect point defects, but not any optical characteristics. If these are not just right, they can be quite distracting for the human eye and in automotive applications may even have dangerous consequences.

For many years, FLOATSCAN inspection systems based on the patented moire technology have been used to reliably identify not only the smallest point defects but also optical warps and line defects. With this technology, the inspection system “sees” just like the human eye, only in a much more reliable manner and without any symptoms of fatigue – and that even up to a glass ribbon width of up to 5800 mm.

The new flagship for in-line float glass inspection – FLOATSCAN Advanced II – provides even more reliable results and improved options for detecting and analyzing defects. As compared to the older generation, it is equipped with significantly improved optical system set-up and a higher resolution.

Moreover, it is based on the very latest camera and PC technology. Both technologies result in a significant increase in the system’s accuracy and stability: core sizes are now determined even more reliably while at the same time the measuring accuracy is optimized. The optical measurement is now at an improved range of +/- 1 mdpt. In addition, zebra values were majorly improved and the definition of such is now even more reliable and more rugged than they had already been in the past. A further advantage: The ground noise that was already very low has been reduced even more.

Along with rugged illumination technology, the inspection system can even detect dark or unwashed glass as well as coating defects or micro tin defects on the upper or lower surface of the glass ribbon reliably and with the highest amount of accuracy. The FLOATSCAN Quality Information System (QIS) that has been proven and tested time and again guarantees fast processing and preparation of all relevant quality and production-related data.

The resulting information, even more reliable than ever before, contributes greatly to further optimizing the production process and to increasing quality and customer satisfaction.
