Researchers introduce first flat optical lens that would be cheaper than convectional lens
The planar that researchers have come up with is a lens that can resolve nanoscale features separated by distances smaller than the wavelength of light. The lens uses an ultrathin array of tiny waveguides, known as a metasurface, which bends light as it passes through, as it happens in a curved lens. The research is described by the researchers in the journal Science.
Soon in future, we will witness large scale production of metalenses at a cost significantly less to what takes to make conventional lenses. The mass production of microprocessors and memory chips would be done using foundries. The lens is made of titanium dioxide nanofins on a glass substrate. The meta-lens focuses an incident light to a spot smaller than the incident wavelength.
"This technology is potentially revolutionary because it works in the visible spectrum, which means it has the capacity to replace lenses in all kinds of devices, from microscopes to camera, to displays and cell phones", said Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering and senior author of the paper..............

....sounds like a game changer
