Ben’s DIY Scanning Electron Microscope

Scanning Electron Microscopes(SEM) are used for visualizing things at a magnification not able to be resolved using light microscopy. And are a terribly valuable tool not only for discovery but also to educate people on the unseen world. However, like most useful scientific tools, they are also terribly expensive, costing anywhere from a few thousand for a used one on Ebay to a few hundred thousand for a brand new one. However, if that’s out of your price range you could always go the DIY route and build your own. Which is exactly what Ben Krasnow did.


You can find more details and keep up to date on Ben’s SEM project at his blog.

Ben Krasnow is also a contributing writer for Citizen Science Quarterly.
