Scanning electron microscope converts to transmission electron microscope with a DIY adapter

A Scanning Electron Microscope was successfully converted into a Transmission Electron Microscope, demonstrating a novel and accessible upgrade. The conversion involved creating a DIY adapter to allow primary electrons to pass through a sample, similar to a TEM's function, overcoming clearance challenges with a custom sample holder. This modification, while requiring precise machining and adjustments, enables detailed imaging of structures like gold nanoparticles and mosquito wings, with future plans to image biological cells.
