Stanford Bioengineer Develops a 50-cent Paper Microscope 83 83

An anonymous reader writes "Scope: A Stanford bioengineer has developed an ultra-low-cost print-and-fold microscope and is now showing others how to make one themselves. The 50-cent lightweight, paper 'Foldscope' — which 'can be assembled in minutes, [and] includes no mechanical moving parts' — was designed to aid disease diagnosis in developing regions." The paper describing the design is on arXiv, and a video demoing the microscope is attached below.

    If you read the article (I know, I know) you'll learn that he uses industrial grit, also known as glass beads, which are tiny bits of glass that are reasonably spherical and ridiculously cheap. The quoted lens cost in the article is $0.17, but unless I'm misunderstanding something, like how special the grit is that he's using, or what kind of secondary selection process is required to pick out beads that will make good lenses, that should be closer to 0.17 cents, not 0.17 dollars.
