Photonic Chip for Achieving Superresolution Light Microscopy

A photonic chip that enables superresolution light microscopy—or ‘nanoscopy’—to be achieved by using traditional microscopes has been developed by physicists at Bielefeld University and The Arctic University of Norway in Tromsø. In the case of nanoscopy, single fluorescent molecules’ position can be ascertained at an accuracy of a few nanometres—or one-millionth of a millimetre.

Super-Resolution Imaging Made Possible by Fabricating Hyperlens Devices

For many centuries, lens makers have worked hard to make a perfect lens with the ability to produce pristine and perfect images. In the year 1873, Ernst Abbe—a German physicist and optical scientist—found out the diffraction limit of the microscope.

Achromatic Flat Lenses Add More Color to the World of Optics

A new, flat lens with the ability to focus light with a higher efficiency within the visible spectrum was reported by a team of researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) last summer. In order to bend and focus light as it passed, an ultrathin array of nanopillars was used in the lens.
