The Paper Microscope

Microscopes are crucial for diagnosing infectious disease. But in some ways they’re the worst possible device—heavy, expensive, and hard to maintain. Paper microscopes, also known as foldscopes, contain all the crucial parts within one foldable sheet of paper. They can be optimized for different diseases and cost less than a dollar.


The Foldscope Instrument has a magnification of 140x and 2 micron resolution. With those capabilities, the many wonders of the microscopic world are at your fingertips!

What Can You See ?


With a magnification of 140x, you can see tiny things like bacteria, blood cells, and single-celled organisms like copepods, tardigrades, tetrahymena, diatoms, rotifers, nematodes and more. As well as larger things like a insects, fabrics, tissues! Foldscope can also allow the observation of non-biological samples, such as particulates detrimental to air quality, or the microscopic crystalline differences between real and fake medications.
