Due to the nature of light, a traditional optical microscope can be employed to attain a maximum magnification of around 800–1000x. For further magnification, scanning electron microscopes (SEMs) can ...

Scanning electron microscopy (SEM) has been an important tool for forensic science since the 1970s, and it continues to find forensic applications today. The technique – capable of 100,000x ...

This degree of magnification and resolution is made possible by the use of a Focused Ion Beam Scanning Electron Microscope, or FIB-SEM. Ordinary microscopes will not produce the same results. Curious ...

Over the last 20 years, the proliferation of research utilizing scanning electron microscopy (SEM) has driven the performance of systems towards higher resolution at lower voltages. This enthusiasm is ...

Cells are tiny, so we use microscopes to see their details. A slide is a thin piece of glass used to hold objects which are examined under a microscope. Peel a thin layer of cells from an onion. Place ...

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 ...

What is scanning tunneling microscopy? STM uses a nanoscale probe to measure the topography and local electronic properties of a sample by scanning the probe over a surface. As the tip is scanned over ...

Today we are machining some metal inside the scanning electron microscope! By creating a custom fixture, we can manually ...
