Our story and the people who make it possible

Our mission

Our mission is to enable new science, improve medicine and enhance manufacturing by redefining the X-ray tube. Wherever new opportunities and applications emerge, we pursue them relentlessly together with the scientific and industry pioneers who transform technological advances into meaningful results.

Our story

Excillum is a global leader in the field of advanced microfocus and nanofocus X-ray sources. Founded in 2007 by researchers from the Royal Institute of Technology (KTH) in Sweden, the company’s first product was the groundbreaking Excillum MetalJet, the world’s brightest microfocus X-ray tube. A few years later, the Excillum NanoTube was created based on advanced electron optics refined from the MetalJet e-beam platform, together with the latest transmission target technology. Today our fast-growing global team applies these core areas of expertise to expand our product portfolio, advance scientific progress and enable unimagined new applications together with leading academic researchers and industrial instrument developers worldwide.

Our customers

With more than one hundred sources deployed worldwide, we continue to develop the world’s most advanced X-ray source technologies based on the daily needs and workflows of a growing global community of innovators. Together with manufacturing inspection system developers, scientific researchers and system integrators, we work in a spirit of open collaboration devoted to cutting-edge science in order to constantly push the boundaries of what microfocus and nanofocus X-ray sources can achieve.
