Vision & Control opens direct access to the fascinating possibilities of machine vision - creating machine vision.

Our mission:
We make machines see and thus make hidden things visible. Our products control production systems in such a way that rejects and complaints are avoided - and thus production can be carried out cost-effectively and efficiently. We enable precision in the µm range 24 hours a day, 7 days a week.
Take advantage of your benefits:
Improve plant efficiency
Our vision solutions promise the highest quality, reliability and precision for improved plant efficiency and work accuracy.
Achieve a cost advantage
For many applications, we already have everything at hand. You can conveniently choose from an extensive range of standard products and thus - modularly and flexibly - put together your own individual solution. This reduces your own development costs.
Strengthening innovative power
