Chemical Vapour Deposition (CVD) Diamond offer extreme hardness, high thermal conductivity, chemical inertness, and high transparency over a very wide spectral range. Stronger and stiffer than Beryllium, with lower thermal expansion and lower toxicity, it is ideal for UHV isolation windows in X-ray beamlines. Windows can be supplied embedded in UHV flanges and with efficient water cooling.

CVD Diamond windows, developed in cooperation with the Fraunhofer Institute of Germany and Paul Scherrer Institute of Switzerland, with the support of Argonne National Laboratory in the USA, are manufactured by Diamond Materials GmbH.
