Material Absorbs More Than 99% of Light
NASA engineers have produced a material that absorbs on average more than 99 percent of the ultraviolet, visible, infrared and far-infrared light that hits it—a development that promises to open new frontiers in space technology. The team of engineers at NASA’s Goddard Space Flight Center, reported their findings recently at the SPIE Optics and Photonics conference, the largest interdisciplinary technical meeting in this discipline. The team has since reconfirmed the material’s absorption capabilities in additional testing, says John Hagopian, who is leading the effort involving 10 Goddard technologists.
