Quality assurance brings economic advantage to manufacturing companies and at the same time contributes to their competitiveness. Mistakes are seen early in the production process to minimize follow-up costs considerably. Non-destructive optical testing of components and parts leads to an efficient testing process without measurably disturbing production procedures. Points difficult to view can be visually checked with little time spent and with no disassembly or even destruction of the test object. The optical inspection with visualization solutions from Robolab can be done as needed, manually or automatically.
