Most people know Nikon as a purveyor of pro and consumer-grade digital cameras. But the company's expertise with optics bleeds over into related markets – it's one of the science community's major suppliers of microscopes.

A panel of scientists and journalists have chosen the best of this past year's submissions, which Nikon has placed on its Small World site.
