Description

Red blood cells (erythrocytes). This image of human red blood cells obtained by scanning electron microscopy, revealing their characteristic biconcave shape.

Technical Details

The scanning electron microscope scans the specimen with a finely focused electron beam and records the number of electrons emitted at each point in the scan as a grey level in the image, with low levels corresponding to few emitted electrons and high levels corresponding to many emitted. Specimens are usually coated with a thin layer of metal to improve conductivity and increase the efficiency of secondary electron emission.
