Visible, invisible... by Milota Sidorova

Have you ever thought about the possibilities of human eye? It is not just perfect combination of optic materials and absolute management and ability to change the focus in microsecond and send these data inside the brain, but it is also limited. Comparing to several animals, especially predators and birds, our eyes are limited by the focus distance. That means we can't zoom for long distances and observe details from several hundreds of meters. Or we can't see very well in the night, just like cats that are able to scale their lenses up to the maximum. To put it shortly human eye can't catch all spectrum of light and can be confused by changing distances. So it means even! our perfect look factory can lie to our brain. Have you ever thought of invisible people or clothes or even buildings? It is not only a fiction, but team of Physicts in Scotland have just recently released progressive development of almost „invisible“ material. It is called Metafles and it is the fabric or flexible material that interacts with the light of around 620 nanometers. For common people it may look like white material that manipulate shadows even colors of the light. Metaflex is made from novel material using technologies based on polymer and sillicon support. Human can perceive light from 400 nanometers to 700 nanometers or catch color spectre from deep violet and purple to deep red. Although Metaflex is still far away from invisible material, so far it can change the characteristics of the light. This feature can be used in optics as well as smart clothing. However, this „invisibility“will be „visible“ just for us – hu! mans who are accostumed for specified light spectres.
