The Micro Phone Lens turns you smartphone (or other mobile device with a 5 MP or larger camera) into a device capable of taking pictures of microscope slide at 150x magnification.
The project had a funding goal of $50,000, which has already been reached. The funding derive continues until April 18 if you are interested in the project. Backers can receive a lens and related merchandise based on the amount of funding. This means you can get one of these lenses by backing the project. (Some funding options are closed right now, but the $50 option that includes a full package is still open.)
The lens has some interesting possibilities by providing inexpensive, portable magnification capabilities.
One use that comes to mind involves doctors performing field work in third world countries. They now have an option for viewing medical slides in the field that doesn't involve expensive medical equipment. The ability to send images of those slides using the phone is an additional plus.
The lens is "focused" by pressing on the slide. The lens housing has some give and pressing on the slide will move it closer to the camera. This is one area where a real microscope has an advantage.
Note: The image above was taken using a prototype lens. The production version will use an aspheric lens which will produce clearer images around the edges.
