Optical near-field scanning microscope.

摘要

The optical near-field scanning microscope comprises an <> (7) attached to the conventional vertical adjustment appliance (6) and consisting of an optically transparent crystal having a metal coating with an aperture at its tip with a diameter of less than one wavelength of the light used for illuminating the object (4). Connected to the aperture-far end of the <> (7) is a photodetector (11) via an optical filter (9) and an optical fiber glass cable (10). Scanning the object (4) is done by appropriately moving the support (3) along x/y-coordinates. …The resolution obtainable with this microscope is about 10 times that of state-of-the-art microscopes.
