NASA engineers including SPIE Member John Hagopian 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 in Greenbelt, Maryland, reported their findings recently at SPIE Optics + Photonics.
The ground-breaking development is gaining wide notice across the photonics community.
The nanotech-based coating is a thin layer of multi-walled carbon nanotubes, tiny hollow tubes made of pure carbon about 10,000 times thinner than a strand of human hair. They are positioned vertically on various substrate materials much like a shag rug. The team has grown the nanotubes on silicon, silicon nitride, titanium, and stainless steel, materials commonly used in space-based scientific instruments.
Tests indicate that the nanotube material is especially useful for a variety of spaceflight applications where observing in multiple wavelength bands is important to scientific discovery.
Co-authors with Hagopian on the paper are Stephanie Getty, Manuel Quijada, and Raymond Kinzer.
