英文释义

名词
  1. a microscope that is similar in purpose to a light microscope but achieves much greater resolving power by using a parallel beam of electrons to illuminate the object instead of a beam of light

百科释义

    An electron microscope is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image. An electron microscope (EM) has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100,000 times shorter than visible light photons.
