Excillum makes the world's brightest microfocus x-ray tube.
The MetalJet technology replace the traditional solid anode of x-ray tubes with a jet of liquid metal. Thereby the achievable power-level is no longeer limited by when the anode melts. It's already molten!
The MetalJet D2 with Montel X-ray optics. Exceptional for X-ray diffraction or scattering.
