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 ...

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

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 ...

Matthew S. Lehnert always had a strong interest in microscopy and loved looking at different specimens through microscopes. He owned three microscopes by the time he turned 8. "I had already decided I ...

From grains of pollen to insects less than a millimeter long, scientists get incredible views of the world by looking through a microscope. And as researchers conduct their studies, sometimes they ...

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 ...
