Excillum offers a growing range of X-ray tubes based on our key technologies. Currently we offer the MetalJet source, based on the company-founding metal-jet-anode technology, and the NanoTube source powered by our refined e-beam technology. Other products are emerging taking further advantage of our general X-ray tube design knowledge. Apart from our standard products we can, of course, also engage in different custom project. Please let us know what you need!


The heart of Excillum’s offering are the MetalJet X-ray sources based on the unique liquid-metal-jet anode technology. The MetalJet X-ray source tecnology is available in the following products:

Key Features

World’s highest microfocus power
Exceptional spot quality
Tuneable source size and shape
High stability
LaB6 long-life cathode
Liquid metal-jet anode technology

MetalJet D2+ 70 kV

The MetalJet D2+ 70 kV is the latest version in Excillum’s line of extreme brightness x-ray sources based on the MetalJet technology. At 70 kV the X-ray source is radiation shielded, with the shutter closed.

MetalJet D2+ 160 kV

The MetalJet D2+ 160 kV is based on the same platform as the 70 kV-version, but it comes with a 160 kV HV-generator.

MetalJet C2

The MetalJet C2 is based on the same MetalJet technology as the D2+ and offers an entry level MetalJet X-ray source with features and performance beyond a conventional solid anode X-ray source and with the future option to upgrade to MetalJet D2+ performance.

MetalJet + X-ray Optics

All MetalJet sources are perfectly suited for integration with X-ray optics to deliver focused or collimated beams of mono- or polychromatic X-rays with state of the art performance. Excillum can offer both complete source+optics solutions as well as advice on integration with optics from third party supplier.



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.

Our Technology

Research & Development

Our mission is to enable new science, improve medicine and enhance manufacturing by continuous development of state-of-the-art X-ray sources.

MetalJet X-Ray

Our MetalJet X-ray tubes are conventional microfocus tubes with the solid-metal anode replaced by a liquid-metal jet.


NanoTube, with unparalleled possibilities for X-ray imaging with true resolution of 150 nm lines and spaces.

Dedicated team

Directly and together with multiple system partners, we have a position on the market as the brightest X-ray source supplier available for home labs.
