An iPhone microscope, which consists of a 1-millimeter-diameter ball lens embedded in a rubber sheet and taped over the iPhone's camera.
A team from the University of California at Davis has developed an affordable way to give the iPhone surprisingly capable chemical detection and imaging powers. We've reported on cellphone microscopes before, but this version claims to be simpler in concept and less expensive, plus it adds spectroscopy to its list of abilities
