Which of the following statements is CORRECT about scanning electron microscopes?
A) Thin segments must be used.
B) The sample is placed in a vacuum.
C) Stains can be applied to improve contrast.
D) Images of surface structures are produced.
E) Glass lenses are used.

Question

Quizplus · Accepted Answer

Scanning electron microscopes produce images of surface structures by scanning a beam of electrons across the sample. The sample is placed in a vacuum and a thin layer of conductive material is applied to prevent the accumulation of static charge. Stains cannot be used to improve contrast, and glass lenses are not used in the electron beam path.
