It is not easy to reliably recognize codes on different glass materials for tracking purposes in production, as a manufacturer of special glass had to learn. With powerful camera sensors and adapted lighting technology, however, the problems, which were always associated with production stops, could be solved in the long term.
Glass is not just glass, and with coatings just a few nanometers thick, its material properties and functions can be decisively changed. One person who can tell a lot of interesting things about this is Peter Röhlen, managing director of Prinz Optics GmbH, based in Stromberg (Hunsrück). "What we do, not many do. This is due to the dip coatings alone in the very rare sol-gel process. We're one of the few companies in the world that use this on an industrial scale."
