A new inspection system for glass containers, e.g. bottles, is under development. The system lay-out fulfills the essential boundary conditions given by the glass manufacturers. In comparison to other systems it yields the best optical resolution. It comprises different inspection sections, such as bottom inspection, side wall inspection, geometry control and wall thickness control within a single mechnical transport system. The first experimental results are very satisfying.
