Scanning electron microscopy (SEM) images the sample surface by scanning it with a high-energy beam of electrons in a raster scan pattern. The primary electron beam, which is produced under high vacuum, is scanned across the surface of a specimen.

The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection Detailed information can be found in the brochure. Scanning electron microscopy (SEM) is one of the most used characterising tools within material research An electron microscope in which a small electron probe is scanned over the surface of a bulk specimen, and secondary or backscattered electrons emitted from The two factors that determine resolution in the scanning electron microscope are accelerating voltage and initial crossover diameter.

When the specimen is irradiated with a fine electron beam (called an electron probe), secondary electrons are emitted from the specimen surface.
