Produktbeschreibung

High Quality Content by WIKIPEDIA articles! An electrostatic lens is a device that assists in the transport of charged particles. For instance, it can guide electrons emitted from a sample to an electron analyzer, analogous to the way an optical lens assists in the transport of light in an optical instrument. The recent development of electron spectroscopy makes it possible to reveal the electronic structures of molecules. Although this is mainly accomplished by electron analysers, electrostatic lenses also play a significant role in the development of electron spectroscopy. An electrostatic lens can also be used to focus an ion beam, for example to make a microbeam for irradiating individual cells.Since electron spectroscopy detects several physical phenomena from the electrons emitted from samples, it is necessary to transport the electrons to the electron analyser. Electrostatic lenses satisfy the general properties of lenses. Systems of electrostatic lenses can be designed inthe same way as optical lenses, so electrostatic lenses easily magnify or converge the electron trajectories.
