A development of a group of German researchers could change the way the cell phone cameras are built. The study, published in the Journal of Optics, describes an alternative way to construct the diaphragm, the element behind the lens determines how much light reaches the sensor – or film – varying its opening. Researchers from the University of Kaiserslautern created an ultrathin device (55 micrometers thick) made with concentric circles made of two layers of glass in the middle of which is a electrochromic materials, ie, which darkens or lightens…
