Even SEMs with newer technology have to contend with these issues. Trying to fire the electrons from higher voltages will just embed them into the target. This creates a low contrast ghostly image we’ve come to associate with SEMs.Īttempting to fire more electrons at the target will de-focus the beam due to the electrons repelling each other. In live video modes, an SEM can only collect one or two reflected electrons off a given section of a target. However, it still has a lot in common with current SEMs. The JSM-T200 is old tech the primary way to store an image from this machine is through a screen-mounted Polaroid camera, much like an old oscilloscope. The JSM-T200 joins homemade SEM, his DIY CT scanner, the perfect cookie machine, and a host of other projects in his lab. The SEM was actually dropped during shipment, but thankfully the only damage was a loose CRT neck plug. He only had to pay shipping from Sweden to his garage. He’s acquired a JEOL JSM-T200, which was hot stuff back in the early 1980’s. Is quite possibly the only hacker with a Scanning Electron Microscope (SEM) collection.
