A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones.No one has yet made a superlens, also known as a perfect lens, though people are trying. Optical lenses are limited by the nature of light, the so-called diffraction limit, so even the best won’t usually let us see objects smaller than 200 nanometers across, about the size of the smallest bacterium. Scanning electron microscopes can capture objects that are much smaller,...

A simple-to-make "superlens" can focus 10 times more sharply than a conventional lens. It could shrink the size of features on computer chips, or help power gadgets without wires. No matter how powerful a conventional lens, it cannot focus light down to more than about half its wavelength, the "diffraction limit". This limits the amount of data that can be stored on a CD, and the size of features on computer chips. Researchers have devised ways to beat the diffraction limit before, using bizarre "metamaterials" that are hard to make, and which are also the basis of prototype "invisibility cloaks"....

Scientists gain insight into invisibility through a complex superlens By Roger Highfield, Science Editor (Filed: 03/05/2006) The Klingons used it to make their Bird of Prey spacecraft invisible. The Romulans used cloaking too and variants of this stealth technology hid the nasty alien in the Predator films and have been mentioned in Star Wars, Doctor Who and more besides. Scriptwriters will be pleased to discover that this science fiction idea is deemed today to be closer to science fact than we realised, according to a paper published in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences....
