An ultrathin, microstructure lens thinner than a human hair can capture images with the same quality as a thicker, standard lens.
The prototype lens was developed by a team from the University of Utah using an array of microstructures that bend light to focus it on the sensor. Each structure contributes a bit of the image, working together to act as a lens. This unique design allows the lens to lie flat instead of curved while measuring just a few microns thick. The new lens can also be made of plastic instead of glass and could find its way into lightweight drones and night-vision goggles.
