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 ...

The scanning electron microscope (SEM) delivers high resolution, high depth of field, and an image quality as if microscopic objects are seen by the naked eye. This makes it not only a powerful ...

Since the first transmission electron microscope was sold in 1935, microscopes that use electrons--rather than light waves--to image objects have brought into focus levels of detail that were ...
