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.
