Lens turns smartphone into a microscope: Costs only 3 cents

Researchers at the University of Houston have created an optical lens that can be placed on an inexpensive smartphone to magnify images by a magnitude of 120, all for just 3 cents a lens.

Wei-Chuan Shih, assistant professor of electrical and computer engineering at UH, said the lens can work as a microscope, and the cost and ease of using it — it attaches directly to a smartphone camera lens, without the use of any additional device — make it ideal for use with younger students in the classroom.
