Optical microscopes are a common tool found in almost all laboratories that illuminate and magnify a specimen. Optical microscopes offer ease of use but have limited resolving power. If a much higher resolution and greater depth of focus is required, then a scanning electron microscope (SEM) might be more useful. SEMs use a beam of focused high-energy electrons to produce information about the specimen including morphology, chemical composition, and crystalline structure.
