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!
