Cambridge, Mass. – August 23, 2012 – Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses.


At a mere 60 nanometers thick, the flat lens is essentially two-dimensional, yet its focusing power approaches the ultimate physical limit set by the laws of diffraction.

This could grow into a major game-changer. There is no reason why such lenses can't be interlaced, which would result in a holographic type of imaging* without the lasers. In addition, such lenses being flat means that common objects could be surfaced with the lenses. Imagine a spy with a book or briefcase that actually is a holographic camera.

*True holograms have such a fine grid of detail that when you move while looking at one, the movement is totally smooth. Interlaced lenses would do some trade-offs and be in a coarser grid, maybe as much as a half-centimeter between optical centers.

Who knows what all might come from this new technology, and it is obvious how happy these guys are.
