Flat lens optics
WebSep 18, 2024 · Now engineers at MIT and the University of Massachusetts at Lowell have designed a wide-angle lens that is completely flat. It is the first flat fisheye lens to produce crisp, 180-degree panoramic images. WebMar 18, 2024 · Researchers at a U.S. university have devised a new kind of flat lens that can give a camera an extreme-depth-of-field, focus-free view (Optica, doi: 10.1364/OPTICA.384164 ).
