The project is actually quite a simple little hack. They use a 1mm ball lens and attach it to the outside of the iPhone lens array with a rubber sheet and some tape. The little lens technically only offers 5x magnification, but the way it focuses creates a tiny in-focus area that can resolve details down to about 1.5 microns. The field of view is very small and there’s distortion to deal with, but by combining the in-focus areas of several pictures you can get a clear enough image to identify cell types, make counts, or even take spectroscopic readings.At the end of the article is a link to the original paper on PLoS ONE.
