About Stellarray

Stellarray is bringing to market innovations for irradiation and imaging using flat panel radiation sources. The company's first products are X-ray panels themselves and a self-contained blood/biological irradiator (SCBI) for ensuring the safety of transfusion blood supplies. Stellarray was spun out of Stellar Micro Devices (SMD) and builds on technology developed by SMD for the Air Force Research Laboratory to safely and rapidly decontaminate biohazards. Panel manufacturing process development was supported by the NIST Advanced Technology Program. All of Stellarray’s radiation panels use cathode arrays, such as our proprietary nano-layered carbon cold cathodes, to provide the shift from point sources, such as X-ray tubes or UV lamps, to panel sources, for major advantages in our target markets. UV radiation panels are made by hitting phosphors with electron beams. The X-ray panels use electron beams from cold 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. In the digitally addressable “Smart X-ray Source”, small groups of cathodes are addressed at specific locations on the panel to make “X-ray pixels”. The X-ray panels can be made in small sizes, e.g. 5” on a side, on up to 20” or more using processes from the flat panel display industry.
