Stellarray is bringing to market innovations that solve important problem in irradiation and imaging. We developed the world’s first flat panel radiation source and have since pioneered several other radiation source platforms with their own ground-breaking capabilities. Our first products are the sources themselves and selected irradiation systems using them. These include our compact Self-Contained Blood Irradiator (SCBI) for ensuring the safety of transfusion blood supplies, the Stellar-Rad™ Product Irradiator for wholesome agricultural and medical products, and the Stellar-Rad™ Digital Research Irradiator that will accelerate experimentation and deepen data sets in cellular and other radiobiology studies.

Stellarray was spun out of Stellar Micro Devices (SMD) and builds on technology developed by SMD for the U.S. Air Force Research Laboratory to safely and rapidly decontaminate biohazards. Panel manufacturing process development was supported by the NIST Advanced Technology Program. The company has received further support from the National Institutes of Health and the Department of Energy, as well as an investment by the Texas Emerging Technology Fund. Stellarray won First Place in the Medical Category in the 2015 NASA/Tech Briefs “Create the Future” Contest.

All of Stellarray’s radiation panels use cathode arrays to make the move from point sources, such as X-ray tubes, to our innovative panel sources. UV radiation panels and pipes are made by hitting phosphors with electron beams. The 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 flat panel X-ray source, or FPXS. In the digitally addressable “Smart X-ray Source”, small groups of cold cathodes are addressed at specific locations on the panel to make “X-ray pixels”, the key to stationary 3D imaging systems. The panels can be made in small sizes, e.g. 5” on a side, to over 20” using processes from the flat panel display industry.

Stellarray has a multi-disciplinary team and works in a well-equipped laboratory and production facility shared with parent company SMD. Click here to view current job openings.
