KETEK is a recognized world market leader in the development and production of silicon radiation detectors in highest quality and is a one-stop supplier for detector solutions
KETEK was founded in 1989 by Dr. Josef Kemmer,
a world-famous scientist in the fields of semiconductor detector concepts and technology
After his death in 2007 the company is managed by Dr. Kemmer´s daughter Silvia Wallner and
Dr. Reinhard Fojt
and everyone contributes significantly to quality. It is our ultimate goal to gain and maintain satisfied and convinced customers. This is achieved through accurate products and services and by competent and friendly cooperation with our customer's staff. These goals require commitment, expertise, and personal responsibility of all employees.
The detector and electronics production is controlled and optimized by quality and cost. Highest yield, on-time delivery, and a zero-defect quality are the objectives of all processes, products, and services.
Moreover, they are essential to ensure the company’s future. End of March 2008 KETEK has been certified by TÜV Management Services for the integration of a quality management system according to ISO 9001:2000 for "sales, manufacturing and development of semi conductor detectors, detector systems and corresponding electronics".

Element Mapping in a Scanning Electron Microscope

SDDs in the APXS MER-A/B Spirit and Opportunity on Planet Mars


Complete portfolio from 7mm² to 100mm² active area
for XRF and EDX with energy resolutions down to 123 eV
KETEK analytical x-ray acquisition systems combine the SDD, supplies & signal processing in compact housings
All you need to operate your VITUS SDD or
AXAS for your specific application


Higher collimated SDD area for
maximum peak to background
VITUS H class SDD modules are dedicated for x-ray energies between 250eV and 30keV in applications as EDS and (T)XRF that require excellent peak to background ratios up to 20.000
Larger active area for shorter measurement times
SDD areas from 10 to 100mm² of our R class types offer higher count rates at given signal strength leading to shorter spectrum acquisition times
The VITUS Standard modules are encapsulated with a nickel cap and low pressure nitrogen filled. Energy resolutions range from 139eV for the VITUS H7 to 160eV for the H80 module.
The achievable cooling performance is a Delta T of 55K which results in typical SDD operation temperatures of -35°C at an ambient temperature of 20°C.
Our Premium Class SDD's offer state of the art energy resolution values down to 129eV and below at 5.9 keV. Detectors with Be window are fully evacuated and offer a superior cooling performance achieving a Delta T of > 75K. The specified minimum FWHM can therefore be guaranteed even at ambient temperartures up to 40°C which is especially important for portable spectrometers.
Premium Class versions with AP3.3 low energy window feature high performance KETEK SDD's (FWHM < 129eV) which are encapsulated with a low pressure nitrogen filling.




Close cooperation with the University of the Federal Armed Forces, Forschungszentrum Dresden as well as Fraunhofer Gesellschaft IZM München are a solid base for a long term road of innovation. Beside of that many long term relationship with research institutes over the world have developed over the 20 years of KETEKs existance.
KETEK is in control of the complete value chain starting with semiconductor technology and processes on silicon, device and system level. With that, KETEK is best fit for new, future challanges. Stay tuned.
