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.
The creation—which they claim is “the first flat fisheye lens to produce crisp, 180-degree […]. petapixel.com
Harvard researchers have made advancements in development of a flat lens known as a metalens – for the first time, it can work with a continuous range of colors rather than one at a time. Research has been ongoing at the University's School of Engineering and Applied Sciences, showing last summer that it was possible to create a lens 100,000x thinner than glass that could focus light in the visible spectrum. dpreview.com »
