This JEOL JSM-5200, originally manufactured in the late 1980s or early 1990s, was given to them by a lab that could no longer repair it.

The video provides an overview of how a scanning electron microscope works, details the repair journey, and features fascinating examples of the microscope’s capabilities in action.
