STEMMER IMAGING is Europe’s largest imaging technology provider for science and industry. The perfect combination of innovative products, intelligent consulting and extensive service helps our customers solve their imaging projects with speed and ease.

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
We have been developing image processing systems "made in Germany" for over 25 years. With a research, development and manufacturing competence that constantly redefines the limits of what is possible in our industry. Benefit from our know-how.
Expanding competence
We are always at your side as a competent partner for practical questions. With an all-round carefree package from development and consulting to commissioning and support, as well as a wide range of consulting and training services: feasibility analyses, solution workshops, training courses and seminars.

Polytec was founded in 1967 to distribute commercial laser technology to industrial and research markets. Building on the company’s early success, Polytec began to develop and manufacture and then manufactured, innovative laser-based test and measurement instruments in the 1970’s. These products have become known around the world as the gold standard in non-contact, laser-based measurement of vibration, speed and length. Advanced product development remains a core strategic activity at Polytec with new electro-optical systems being designed for analytical process measurement, noise analysis, and factory automation.
Polytec develops state-of-the-art laser-Doppler vibrometers and velocimeters designed to solve our customers’ difficult manufacturing, development and research challenges. Polytec vibration analysis systems, length and speed sensors for production processes or optical surface profiling systems support high-quality research, development and manufacturing processes worldwide.
Polytec also distributes, markets, sells and services sophisticated opto-electronic systems and components in select European countries. Besides, Polytec provides analytical measuring systems as an over-all solution for diverse applications in R&D laboratories, for process control and monitoring in industrial facilities.
