Question 1

What is a scanning electron microscope?

Accepted Answer

A scanning electron microscope (SEM) is an advanced imaging tool that uses a focused beam of electrons to create high-resolution images of samples.

Question 2

What industries use scanning electron microscopes?

Accepted Answer

SEMs are used in materials science, biology, semiconductor manufacturing, quality control, nanotechnology, and forensic analysis.

Question 3

How does SEM differ from optical microscopy?

Accepted Answer

SEM provides greater depth of field and resolution than optical microscopes, allowing for detailed imaging at the nanoscale.

Question 4

What are the key features to look for in an SEM?

Accepted Answer

Key features include resolution, magnification range, sample size capability, and integrated analytical tools like EDS.

Question 5

Can SEM analyze the composition of materials?

Accepted Answer

Yes, SEM can perform elemental analysis using techniques like Energy Dispersive X-ray Spectroscopy (EDS) to determine material composition.
