About ZeCoat Corporation

ZeCoat Corporation develops advanced thin-film optical coatings and vacuum-deposition technologies for demanding astronomy, aerospace, and scientific applications. Founded in 2011, we bring together expertise in coating design, physical chemistry, electronics, mechanical engineering, and software development to solve challenges that conventional coating systems cannot. At our manufacturing facility in Granite City, IL, our cleanroom, optical measurement laboratory, and motion-controlled electron-beam evaporation systems enable us to coat substrates up to two meters in diameter with exceptional uniformity and layer precision. Our capabilities include protected silver, far-ultraviolet aluminum, protected gold, multilayer dielectric, thermal-control, silicon-cladding, and ultra-black coatings. Technologies developed by our team have supported landmark missions and programs including the Kepler Space Telescope, Mars InSight, PACE, Chandrayaan-1, NuSTAR, and NASA’s starshade research. Today, we continue to advance the field through next-generation coatings, large-optic deposition systems, roll-to-roll processes, and technologies designed to apply or renew optical coatings in space.
