A team of researchers from the Harvard University have designed an ultra-thin meta-lenses that could revolutionize each form of optics, including microscopes and contact lenses. The relatively new type of flat lenses can replace the curved glass optics that are currently used in almost all types of imaging appliances.
A flat lens created with titanium dioxide by a team of Harvard researchers can revolutionize optical technology and lead to the manufacture of smaller cameras and telescopes.
