About Us
With our detectors the world is getting to the bottom of materials
– for engineers, scientists and other curious people.
At KETEK in Munich, Germany, an experienced team of highly motivated engineers, physicists and technicians is developing and manufacturing a unique product portfolio around the Silicon Drift Detector, starting from the bare silicon wafer to the detector chip and further to the highly complex detector module.
We are offering our customers, located everywhere in the world, tailored solutions for their analytical devices and applications, including our in-house-developed analog and digital signal processing electronics.
KETEK has been certified by TÜV Management Services for the integration of a quality management system according to ISO 9001:2015 for “manufacturing and development of semiconductors, detector systems and corresponding electronics.”
