When you buy through link on our web site , we may gain an affiliate commission . Here ’s how it work . Physics could presently make it possible to replace those bulky , heavy , glass lenses on cameras with wafer - lean " metalenses " — materials microscopically engineered tofocus lightat a fraction of the weight and size of traditional lensing . A squad from Harvard University ’s school of applied science has designed a metalens that can focus nearly the entire spectrum of visible light , the researchers reported Jan....
