The team of scientists from Harvard made new, tiny, lens that can go on your phone and is likely to be competing with DSLR cameras in not so distant future. The prototype of the invention was given to interested audience and a report was presented on the pages of Science.
New miniature lenses can be used in any sphere, including photography as well as in any telescopic equipment. Your smartphone is not an exception either. The size of the lens is tiny, around 2mm in diameter and costs 2-3 times cheaper to manufacture when comparing to similar lenses currently available.
