Ray High-energy optics

cosine’s High Energy Optics business unit is world-leading in the development and application of X-ray optics and systems. We combine and apply knowledge about semiconductor processes, silicon, glass and mass production to develop and produce light-weight, high-resolution X-ray optics. Those find applications ranging from space-based astro-physical applications to medical, semiconductor and material analysis systems used by industry and academia.

Space-based astronomy

cosine staff has been involved in different high-energy astrophysics missions for over 20 years. We have worked on ESA missions such as Beppo-Sax and XMM-Newton, but also on NASA missions such as NuStar and NICER. We have actively worked on the high-energy optics, on their calibration, on the science data analysis and on the simulators used for these missions. cosine now uses that unique expertise and heritage to develop and produce the optics for the next generation X-ray telescopes, such as Athena and ARCUS.


Optics design and production expertise is essential to develop new high-energy optics systems for medical applications. cosine staff designs, models and builds reflective X-ray and Y-ray focusing and imaging systems and is acquainted with the latest source and detector technologies to develop new solutions for medical applications.

Material analysis

X-rays interact with matter and can be used to analyze material composition by using techniques such as for example fluorescence spectroscopy or X-ray diffraction. Through cosine’s heritage in the design and production of high-energy optical systems, we have the necessary expertise to design new systems for material analysis. We use the latest techniques and detectors developed for highly-demanding space applications to come up with innovative systems.
