Vantablack

Vantablack new material developed so devoid of reflection, that’s the world’s darkest material, looks like a black hole.    Image credit Surrey NanoSystems.

Vantablack by U.K.-based Surrey Nanosystems, could help space cameras see better, absorbs all but 0.035 percent of the incident light that bounces off it. It’s made of carbon nanohair that is 1,000 times thinner than the average human hair.



Ben Jensen, chief technical officer of Surrey Nanosystems, said:

“You expect to see the hills and all you can see … it’s like black, like a hole, like there’s nothing there. It just looks so strange.

Vantablack is a major breakthrough by UK industry in the application of nanotechnology to optical instrumentation.  For example, it reduces stray-light, improving the ability of sensitive telescopes to see the faintest stars, and allows the use of smaller, lighter sources in space-borne black body calibration systems. Its ultra-low reflectance improves the sensitivity of terrestrial, space and air-borne instrumentation”

Vantablack has not only the ability to absorb visible light, it also absorbs other types of radiation, including more than 99.85 percent of the infrared radiation.
