| Abstract | We are developing a modular (scanning) transmission electron microscope (S)TEM, referred to as NanoMi, which is released under an open source license by the National Research Council, Canada; see for updates.
The electron microscope (EM) is a critical enabling tool in the physical, materials and biological sciences but its impact could be increased by the availability of an easy-to-build, customizable instrument capable of modest resolution and suitable for electron beam lithography, specialized experiments and for training personnel. An instrument that can be built for ~50 k$ and ~1 year of student time would fulfill these requirements in many laboratories around the world. Here we describe an initial design of such an instrument. |
