MetalJet, the world’s brightest microfocus X-ray tube

The MetalJet technology replaces the traditional solid anode of X-ray tube with a jet of liquid metal.
Thereby, the achievable power-level is no longer limited by when the anode melts.
It’s already molten!

The MetalJet X-ray source can then be integrated into one of our partners’ systems or constitute the base of a custom set-up solution.

Our Story


It started already in year 2000 with the invention of the liquid-metal-jet-anode principle by Prof. Hans Hertz and Ph.D. student Oscar Hemberg. The technology was then further refined by Ph.D. students Mikael Otendal and Tomi Tuohimaa. At that time the four founders-to-be were affiliated with KTH Royal Institute of Technology in Stockholm.


Excillum AB Founded

The foundations of the MetalJet principle were now demonstrated and Excillum was founded to bring the technology to the market. With some investment capital on board, a few more engineers could be added to the team to explore and refine the technology further, focusing on developing the first product, MetalJet D1.


First Market – X-ray Diffraction

First system integration is for X-ray Diffraction through a close cooperation with Bruker-AXS and by then sales started to grow, as well as the team though still small. With some further development, the next generation MetalJet, D2 was launched.

New Product Launch

A first step towards being a multiple-products company is taken with the launch of the new product, NanoTube, with unparalleled possibilities for X-ray imaging with true resolution of 150 nm lines and spaces and with the unique feature to internally measure and report the current spot size.


Ready for greatness!

Team is expanding and ambition is growing. Directly and together with multiple system partners, we are reaching for new geographical markets and application segments as well as consolidating our position on the market as the brightest X-ray source supplier available for home labs.

Our Partners

Here we present a selection of our Partners with links to showcase how they have successfully integrated MetalJet, to the benefit of their customers.

Our Vision and Mission


Our vision is to be the world’s leading innovator and supplier of premium X-ray sources.


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