Researchers Develop a Flat Metalens That Can Change Its Focal Length
An international group of researchers has developed a metalens that is able to have its focal length changed and controlled using polarized light.
Canon is Making Metalenses, Further Legitimizing the Technology
Metalenses are a relatively fringe optical technology -- at least, they were. Until now, it has been largely pursued by startups and scientists but that is changing as Canon has jumped into the fray and not only makes them but also produces the equipment necessary to manufacture them.
Single Flat Lens Used to Photograph the Moon for the First Time Ever
A Penn State-led research team has developed a flat, single-lens telescope that was able to capture clear images of the moon. Known as a metalens, it achieved far greater resolution and imaging distance than any metalens before it.
New Light Field Camera Can Focus Up-Close and Far Away Simultaneously
A new nanophotonic light field camera based on the eye of a Cambrian-era sea creature can combine macro and telephoto magnification into one lens with unlimited depth of field.
Compact Wide-Angle Metalens Camera Eliminates Bulky Glass Optics
The development in metalens technology continues, and researchers have designed a new compact camera that takes high-quality wide-angle photos and eliminates the typical bulk of optics.
Researchers Shrink High-Res Camera Down to the Size of a Grain of Salt
Researchers from Princeton University and the University of Washington have developed a high-resolution, full-color camera that is the size of a grain of salt that is the next generation of metasurface technology.
Samsung Researching Flat, Metalens Tech for Smartphone Integration
As part of an industry presentation on nanotechnology in Seol, Korea, Samsung executives revealed that the company is researching metalens technology, which refers to a flat lens system that instead uses nanoparticles to align light rather than relying on curved optics.
Revolutionary ‘Spaceplate’ Could Eliminate Traditional Camera Lenses
Researchers from the University of Ottawa have developed a concept that would reduce the size of lenses by a huge margin and effectively eliminate the size of modern optics if combined with a metalens. The team tackled not lens elements themselves, but instead the space between them.
MIT Engineers Create Camera Lens That Focuses With No Moving Parts
Using physical glass elements for camera lenses has been at the core of imaging technology for centuries, but MIT engineers have now fabricated a new "metalens" that can focus on objects at multiple depths without changing its physical position or shape.

MIT Engineers Created a 180° Fisheye Lens from a Single, Flat Piece of Glass
A team of engineers at MIT and the University of Massachusetts at Lowell have created something that, on the surface, seems impossible: they've designed a 180° fisheye lens from a single, 1mm-thin piece of calcium fluoride glass that is completely flat.
