High-Resolution, 3-D,
Whole-Cell Imaging
for the Laboratory​

The  SXT100  is the only commercial, lab-based solution for imaging subcellular structure.


No other high resolution imaging modality is capable of quantitatively imaging the subcellular organization of whole hydrated cells, up to 15μm thick at resolutions up to 40 nm, in their native state, with very little preparation and without the use of stains or other contrast enhancing agents.

Using innovation in laser produced plasma source
technology to "miniaturize the synchrotron"

The key technology at the core of the SXT100 is a high-performance soft x-ray light source based on laser-produced plasma emission. The tiny fireball produced emits the soft x-rays that are used for cell imaging but it also produces a lot of metal debris. Patented, self-healing optics are then employed to collect, filter and focus the soft x-rays onto the cell sample to be imaged.

Sirius XT spun out of the UCD School of Physics Spectroscopy Group in 2015 and is based in Dublin, Ireland. The vacuum-based laser-produced plasma technology, which is the core technology that underpins the SXT100, has been developed at UCD since 2005 by a team of internationally-renowned plasma physicists.
