Excillum products

Explore a new era of X-ray source technologies

Excillum offers a growing range of X-ray tubes based on our key technologies. Currently we offer the Excillum MetalJet source, based on the company-founding metal-jet-anode technology, and the Excillum NanoTube source powered by our refined e-beam technology. Other products are emerging taking further advantage of our knowledge in cutting-edge X-ray tube design. Apart from our standard products we also engage in different custom projects.


At the heart of Excillum’s offering are the MetalJet X-ray sources based on our unique liquid-metal-jet anode technology. The metal-jet technology enables significantly higher brightness and smaller spot sizes than any other available microfocus X-ray source, achieving the closest possible to synchrotron performance in the home lab.


The NanoTube is based on advanced electron optics refined from the workhorse MetalJet e-beam platform and the latest tungsten-diamond transmission target technology. Automatic e-beam focusing and astigmatism correction ensures that the smallest possible, truly round spot is achieved at any voltage and current setting.

Custom products & solutions

The technology developed for our standard portfolio of X-ray sources can also be used to create custom products for OEM partners for e g imaging and analytical systems. On a case-by-case basis we evaluate a possible match between your system requirements and our technology, together with you.
