Flat Lens Offers a Perfect Image
August 23, 2012
Applied physicists at the Harvard School of Engineering and Applied Sciences have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. It operates at telecom wavelengths--i.e., those used for fiber optics--and is scalable to a wider range.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering.
