Due to the simple and fast measured value acquisition of our optical measuring systems, vajotec is particularly interesting for the quality management of your vacuum coating systems. Thereby, our products can perform measurements both before and after coating.

Vajotec is patent owner for wireless measurement methods. Therefore, only with us you can get efficient measurement methods and yet our products are more cost effective compared to other industries.

enowned customers in research and production of filters, mirrors, AR layers, solar cells, LEDs, lamps and semiconductors already use measurement systems and radio applications from vajotec to increase efficiency and effectiveness in their work.
