Vantablack – A Material Too Black To See

vantablack-sAccording to The Independent –

A British company has produced a “strange, alien” material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the “super black” coating made of carbon nanotubes – each 10,000 times thinner than a human hair – is an odd experience. It is so dark that the human eye cannot understand what it is seeing. Shapes and contours are lost, leaving nothing but an apparent abyss. Actual applications are more serious, enabling astronomical cameras, telescopes and infrared scanning systems to function more effectively. Then there are the military uses that the material’s maker, Surrey NanoSystems, is not allowed to discuss.

Is Cloaking Technology About To Become Reality?

According to BBC –

Tiny carbon tubes can be used to hide three-dimensional objects from view, according to a team of researchers. The nanotubes are one-atom thick sheets of graphene wrapped into cylindrical tubes. Engineers from University of Michigan found they could be used to obscure objects so that they appeared to be nothing more than a flat black sheet. The team suggest “forests” of the material may one day be used to cloak spacecraft in deep space. The group says the technology works because the nanotubes’ “index of refraction [is] very close to that of air”. This means they slow down light to a similar degree. As a result there is very little scattering of light as it passes from the air into the layer of nanotubes.
