报告摘要:

 The conventional optical microscope is traditionally one of the most important tools with which to view and study samples under high magnification. A long historical development has led it to be used in many fields such as the biological sciences and materials research. However, the spatial resolution attainable with conventional optical microscopy is limited to the Abbe diffraction limit, approximately half of the wavelength of the light source used and has not significantly changed since the compound lens system was first invented. Many kinds of higher resolution techniques such as transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning electron microscopy (SEM) and scanning tunneling microscopy (STM) have been developed in recent decades. However, the achievements of higher spatial resolution offered by these systems have been made at the expense of the optical contrast mechanisms available to optical microscopy. These newer microscopes also have many limitations in terms of sample preparation requirements, observation environments and so on. However, one example combines higher resolution with the advantages of traditional optical microscopy. This is scanning near-field optical microscopy (SNOM).In this talk, the historical development of the scanning near-field optical microscopy and its applications in material science will be presented.
