This new flat lens technology will allow cameras and microscopes to be produced in smaller sizes with less image distortion than ever before.
Typically, the lenses in eyeglasses and microscopes have to be made with a curvature. The curvature in the lens bends light, focusing it to a small point. Now, a team of researchers have found out how to make a flat lens that accomplishes the same process. The flat lens is composed of "silicon nanopillars," which are columns one one-billionth of a meter tall.
Because of its shape and micro size, the flat lens will be able to fit into truly miniature electronics without compromising image quality. Furthermore, the flat lens is made of silicon and will therefore be much more durable than current glass lenses.
