A home machinist and microscopy enthusiast has documented a detailed technical conversion of a ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Traditional electron microscopy techniques include scanning electron microscopy (SEM) and transmission electron microscopy (TEM), where electrons that interact with the sample are imaged. 4 The ...
