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.

According to the team, the new lens is flexible, can resolve objects as small as 200 nanometers, and can even see into the near infrared. This is possible a it breaks the diffraction limit and allows a focus of less than half the wavelength of light.

Once the technology is mature, the team sees it as having applications beyond microscopy, such as in lighter, thinner mobile phones with thermal imaging capabilities, smaller endoscopes for surgery, as a replacement for conventional lenses in nanosatellites to save a couple of hundred grams of launch weight, and to increase the efficiency of photonic chips in supercomputers and superfast broadband distribution.
