Revolutionary lens 5x thinner than a sheet of paper : Scientists from Université Laval’s Faculty of Sciences and Engineering have invented a lens five times thinner than a sheet of paper that is able to zoom in and out without mechanical parts. Tigran Galstian and Vladimir Presnyakov present this amazing piece of optical instrumentation in the latest issue of the Journal of Applied Physics. "There are several possible applications for such a lens. We believe one of its most promising developments could be in camera-embedded cell phones," says Galstian. "Our opto-electrical zoom lens would be of much higher quality than the ones that currently equip these phones."
