Graphene Optical Lens a Billionth of a Meter Thick Breaks the Diffraction Limit (gizmag.com)

Zothecula writes: With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the Swinburne University of Technology has developed a graphene microlens one billionth of a meter thick that can take sharper images of objects the size of a single bacterium and opens the door to improved mobile phones, nanosatellites, and computers.
