[Leica] High resolution lens

[lrzeitlin at aol.com]

 A report just came across my desk about a novel flat lens developed at Harvard University which promises a 30% higher resolution than the best conventional lens. The increase in resolution occurs because the lens is free of all of the aberrations which must be corrected for lenses based on spherical glass surfaces. The lens, made of carefully deposited filaments of titanium dioxide on a glass surface should be considerably cheaper than one made of carefully ground exotic glass elements because of the very low cost of the materials. This is akin to the revolution that occurred in telescope optics when coated mirrors replaced glass lenses. Apparently the first application will be in microscope optics and cell phone cameras but there is no limit to the size that the new lenses can be made. Does anyone have information on this?
