Near-field scanning optical microscope with a metallic probe tip
Optics Letters, 1994A near-field scanning optical microscope with a metallic probe tip was developed for detecting localized photons near the surface of the fine structure of a sample. In this microscope a metallic probe is used for converting the evanescent photons localized near the sample surface to the propagating scattering light wave; the scattered light is detected

Near-field optical microscope with a multiheight scanning–imaging mode
Optics Letters, 1997A near-field scanning optical microscope has been developed to yield optical images with various gap distances between the probe and the sample surface. The microscope uses an apertureless metallic probe, the position of which is controlled by regulation of the tunneling-electron current from the probe to the sample and by computer-generated bias ...

Imaging ‘intact’ myofibrils with a near‐field scanning optical microscope
Journal of Microscopy, 1997Fluorescently labelled myofibrils were imaged in physiological salt solution by near‐field scanning optical microscopy and shear‐force microscopy. These myofibrils were imaged in vitro, naturally adhering to glass while retaining their ability to contract. The Z‐line protein structure of the myofibrils was antibody labelled and easily identified in the

A Scanning Near-Field Optical Microscope Approach to Biomolecule Patterning
Bioconjugate Chemistry, 2001In view of future generations of biosensors and advanced biomaterials, photochemistry in the near field using scanning near-field optical microscopy is investigated. The potential of direct near-field-induced photoactivation is demonstrated on standard photoresist.

A Stand-Alone Scanning Near-Field Optical Microscope
1995A scanning near-field optical microscope (SNOM), where the tip is scanned rather than the sample, is presented. The advantage of this ‘stand-alone’ type SNOM besides its compact setup is its ability to scan on arbitrarily extended samples. Furthermore, the sample can be manipulated during scanning (e.g.

Scanning Near-field Optical Microscope Designed for Operation in Liquids
Surface and Interface Analysis, 1997We report on the construction of a scanning near-field optical microscope (SNOM), which has been designed to permit imaging at the solid/liquid interface. The probe consists of a tapered fibre tip and the so called lateral sbear force is used for the tip-sample distance regulation. The liquid environment causes damping of the tip vibration and lowering

Optical Integrated Waveguides Characterization by Scanning Near Field Optical Microscope
MRS Proceedings, 1999AbstractIn this work, we present (i) the development of a scanning near-field optical microscope (SNOM) for the characterization of optical integrated devices and (ii) the description of a new lithographic technique for the modification of standard integrated optical waveguides.

Optics Letters, 1996
Diffraction of the localized optical near field by a subwavelength-sized probe (metallic circular aperture) is studied by a nonglobal approach. The problem is closely relevant to the basic principle of a near-field scanning optical microscope (NSOM). We obtain analytic expressions of the diffracted far field from which the transfer function of the NSOM

Real-time Photonic Measurements, Data Management, and Processing III, 2018
A Scanning Near-field Optical Microscope (SNOM) devoted to a commercial Environmental Scanning Electron Microscope (ESEM) is demonstrated in this paper. The system can be applied to biological samples and optoelectronic devices at the nanoscale to obtain their surface topography information and fluorescence spectroscopic information in situ.

A simple scanning head for scanning near-field optical microscope
Ultramicroscopy, 1998Abstract A novel scanning head for a scanning near-field optical microscope (SNOM) is developed. The sample is mounted at the top of a piezo scanning tube, and the sample can be translated manually in its plane at 3 mm range. The principle of the translation mechanics is based on the scanning tube tilting around its `root point', so that the head ...
