The essential innovation in Stellarray’s radiation sources, covered by several pending patents, is to produce the electron beams which make radiation using a cathode array, so the source can be a flat panel instead of a point-source or linear tube. We do not yet have FDA approval for panel sales. To learn more about panel availability please contact us at

UV Panels

These look like double-paned windows, but emit different wavelengths of UV light, depending on the phosphor. Our partners at the Georgia Tech Research Institute developed the UV-C phosphors used in the Air Force decontamination project (“Anthrax killer does its work with no muss, no fuss”). Stellarray’s UV-C panels solve several problems with UV lamp technology by eliminating hazardous mercury and improving efficiency in a compact, safe, easy-to-clean glass panel format that can be used as a structural component. Panels with other UV wavelengths will be used in industrial processes, such as curing epoxies, and in photolithography.

Flat Panel X-ray Sources

Our plain X-ray panels use electron beams from cathode arrays fabricated on one side of the panel to strike a metal target (anode) on the opposite side; the X-rays then exit out past the cathodes. If all the cathodes are turned on at once, X-rays emit from the entire panel area, for a plain flat panel X-ray source, or FPXS. The anode is part of the vacuum envelope, and exposed for cooling, so these panels can deliver high power. They can also be scaled to cover wide areas, so other applications will include medical product sterilization, water and waste water treatment, food sterilization and materials processing.

Digitally Addressable X-ray Sources

In our digitally addressable X-ray source, or DAXS, small groups of cathodes are addressed at specific locations on the panel to make “X-ray pixels”. These panels will also be used in several market segments, mainly in medical imaging, where they will replace huge, expensive and performance-limiting mechanical gantries with digital addressing of X-ray pixels for CT systems with no moving parts.
