Since the resolution of NSOM does not depend on the wavelength of the light, visible and near ...Fabrication of a double-tapered probe with enhanced aspect ratio for near-field scanning optical microscopy Authors. Shuji Mononobe; Content type: Invited Paper Published: 21 September 2015; Pages: 1365 - 1368; Three-dimensional nano-optical assembly of antenna structures with collective near-field coupling Authors ...

In coherent homodyne apertureless scanning near-field optical microscopy (ASNOM) the background field cannot be fully suppressed because of the interference between the different collected fields, making the images difficult to interpret. We show that implementing the heterodyne version of ASNOM allows one to overcome this issue. We present a comparison between homodyne and heterodyne ASNOM ...It has been believed that the resolution in scanning-based microscopy is defined by the probe size, but this postulate is not valid in scanning three-dimensional X …The scanning capabilities of a commercial atomic force microscope are often used in near-field microscopy. There are two basic types of near-field techniques: the aperture and apertureless probe techniques. The main difference between them is in the design of the probe used to scan the sample (see Figure 1 ).We have enhanced the apertureless scattering-type scanning near-field optical microscope by two improvements which together achieve a recording of the true near field without any height-induced artefact. These are the use of interferometric detection of the scattered light on one hand, and the use of higher-harmonic dither demodulation of the ...Near-field scanning optical microscopy (NSOM) allows simultaneous topographic and fluorescence imaging using an optical fiber probe with a subwavelength aperture (8-10). The optical resolution, determined by the probe aperture size, is approximately an order of magnitude better than the diffraction-limited resolution (γ/2) of conventional ...

A new method for high-resolution imaging, near-field scanning optical microscopy (NSOM), has been developed. The concepts governing this method are discussed, and the technical challenges encountered in constructing a working NSOM instrument are described. Two distinct methods are presented for the fabrication of well-characterized, highly ...Conventional optical imaging techniques have a fundamental resolution limit due to the diffraction limit of light. The advances of science and technology on the nanoscale demand a new tool for characterization. The Near Field Scanning Optical Microscopy (NSOM) has been developed to tackle certain aspects of this problem. The work presented here applies different types of NSOM to explore the ...This section contains selected literature references to original research reports, books, and review articles on near-field scanning optical microscopy.

There is a great need to determine shape, size, chemical composition, molecular structure and dynamic properties of nano-structures. To do this, microscopes with high spatial, spectral and temporal resolution are required. Scanning Near-field Optical Microscopy (SNOM) is a new step in the evolution of microscopy. One possible solution involves the use of near-field scanning optical microscopy (NSOM), which can optically image a sample with spatial resolution beyond the optical …

Plasmonic nano-antennas are pushing the limits of optical imaging resolution capabilities in near-field scanning optical microscopy (NSOM).

Here we discuss selected applications of NSOM to biological systems that help illustrate the utility of its high spatial resolution and simultaneous collection of both fluorescence and topography. For the biological sciences, these ...Near-field scanning optical microscopy. The NSOM for imaging fixed, dried cells used an adiabatically tapered, Al-coated single-mode optical fiber probe with an aperture with a diameter that is typically ∼80 nm. Blue (488-nm) light from a Kr/Ar laser or 543-nm light from a green He-Ne laser was coupled through the fiber probe for the ...
