Paper-thin, distortion free, lens

Researchers at Harvard School of Engineering and Applied Sciences have been able to come up with something which may revolutionize the world of cameras. These researchers have created a new kind of camera lens which is virtually as thin as a paper.

To be specific, it measures a mere 60 nanometers in thickness and makes use of a gold-plated silicon wafer. Parts of the gold plate are chipped away to leave behind several V-shaped structures, evenly distributed along the surface in near rows. It is then by tweaking the size, angle and orientation of these V-shaped structures that the lens is able to capture wide-angle distortion-free images.
