The world's smallest X-ray nanospot
NanoTube N3
The Excillum NanoTube N3 enables industry-leading 150 nm resolution in geometric-magnification X-ray imaging systems up to 160 kV depending on source model. High flux and exceptional spot stability make the source ideal for demanding 3D computed tomography applications as well as 2D imaging in both industrial and research environments.
The Excillum NanoTube N3 is based on advanced electron optics and the latest tungsten-diamond transmission target technology. Automatic e-beam focusing and astigmatism correction ensures that the smallest possible, truly round spot is consistently achieved during day to day operation.
The NanoTube N3 also has the unique feature of internally measuring and reporting the current spot size. In addition, advanced cooling and thermal design results in extreme stability over long exposures. This enables an unprecedented true resolution of 150 nm lines and spaces.
