scanning electron microscope Bedeutung

electron microscopy microscopy with the use of electron microscopes
electron spin resonance
ESR
electron paramagnetic resonance 		microwave spectroscopy in which there is resonant absorption of radiation by a paramagnet
scanning the act of systematically moving a finely focused beam of light or electrons over a surface in order to produce an image of it for analysis or transmission
binocular microscope a light microscope adapted to the use of both eyes
compound microscope light microscope that has two converging lens systems: the objective and the eyepiece
electron accelerator collider that consists of an accelerator that collides electrons and positrons
electron gun the electrode that is the source of electrons in a cathodeay tube or electron microscope, consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
electron microscope 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
electron multiplier a vacuum tube that amplifies a flow of electrons
field-emission microscope electron microscope used to observe the surface structure of a solid
hand glass
simple microscope
magnifying glass 		light microscope consisting of a single convex lens that is used to produce an enlarged image, the magnifying glass was invented by Roger Bacon in
lens electron lens electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons
light microscope microscope consisting of an optical instrument that magnifies the image of an object
microscope a magnifier of the image of small objects, the invention of the microscope led to the discovery of the cell
operating microscope binocular microscope used in surgery to provide a clear view of small and inaccessible parts of the body (as in microsurgery)

Als Rasterelektronenmikroskop bezeichnet man ein Elektronenmikroskop, bei dem ein Elektronenstrahl in einem bestimmten Muster über das vergrößert abzubildende Objekt geführt wird und Wechselwirkungen der Elektronen mit dem Objekt zur Erzeugung eines Bildes des Objekts genutzt werden. Die typisch mit einem Rasterelektronenmikroskop erzeugten Bilder sind Abbildungen der Objektoberflächen und weisen eine hohe Schärfentiefe auf. Eine rasternde Abbildung lässt sich auch in Transmission durchführen , hierfür sind entsprechend ausgerüstete Transmissionselektronenmikroskope oder dedizierte Rastertransmissionselektronenmikroskope nötig.
