  • Near field scanning optical microscopy
    Patent number: 4917462
    Abstract: An aperture probe in the form of a tapered metal-coated glass pipette having a thin tip provides near-field access to a sample for near-field microscopy. The pipette is formed from a glass tube drawn down to a fine tip, and then coated, as by evaporation, by a metallic layer. The central opening of the tube is drawn down to a submicron diameter, and the metal coating is formed with an aperture at that opening. Aperture diameters down to 500 Angstroms diameter are provided. Also disclosed is a microscope utilizing the pipette aperture for scanning near-field imaging of samples.
