VANTABLACK


VANTABLACK
An aluminum foil coated with vantablack material, and it is noted that the ripples of the foil appear to have disappeared at the position of the vantablack
Black materials are easy to see with the naked eye, especially that black is one of the most mysterious colors, where some see it as a symbol of sadness and pessimism, while others see it as a symbol of beauty and elegance, but it is strange that there is a very dark substance that cannot be seen.

A British company specializing in nanotechnology has produced a strange substance called "Vantablack" that is so dark black that it cannot be seen, and the company says it is the darkest material on the face of the earth to the point that the eye cannot distinguish its shape and what it is.
The Vantablack coating is made by the chemical cultivation of a network of carbon nanotubes of small dimensions: a diameter of 20 nanometers and a height of fourteen to fifty (Microns), placed in a high-temperature room, and the nanotubes are very small and dense so that reports may She explained that more than a billion pieces take only one square area of ​​ten square centimeters, and when placed on a surface of any material - say, from aluminum - the light is not reflected, but rather absorbed as a result of hitting the carbon paint, and from the intensity of the blacktop black, some people think that the images Captured are fake images using (Photoshop - Photoshop) to erase all the features of the image to appear completely black, and you can distinguish the Fantastic only when you compare it with things around it and from several angles.

The VANTABLACK has the ability to absorb 99.96% of the light it is exposed to, knowing that the black materials recognized in the world absorb the light by between 95 and 98%, and during its filming glossy paper was placed around it to show it in the pictures.
What distinguishes the material vantablack are its applications, the most important in the field of electronic imaging, and target-setting systems for military uses, as well as in telescopes to improve the ability of telescopes to monitor the stars very fading.

 Vantablack is a new technological breakthrough in nanotechnology applications, specifically in the field of optical devices and devices. It will reduce scattered light, which improves the ability of sensitive spars to see dim stars, and also allows the use of smaller and lighter sources in calibration systems for transported black objects in space or air.

The company also announced the launch of a version of a spray called "Vantablack S-VIS", which is expected to make the paint more accessible to anyone who wants to use it, even though it is not at the same level as the darkening of the vantablack.

Representatives of the British company told reporters that they believed that Vantablack could also be used to improve the performance of cameras and sensors, and the only disadvantage is the extreme sensitivity of the coating which impedes its usability in commercial applications, although it has been used in some star-tracking satellites.
