A compact near-field scanning optical microscope
Ultramicroscopy, 1998Abstract We present a recently constructed near-field scanning optical microscope which incorporates improvements over our previous designs. This microscope features an ultra-fine mechanical tip/sample approach with continuous submicron control over a range of several millimeters.

A metamaterial-scanning near-field optical microscope
Microwave and Optical Technology Letters, 2006like a PMC surface for this direction of observation. It can also be noted that the fields are zero for /2, except when 0 and . Thus, the field will propagate along the surface in the direction of the strips, that is, in the direction for which the surface behaves like a hard surface. This corresponds to localized surface waves following the strips, as

A cryogenic scattering-type scanning near-field optical microscope
Review of Scientific Instruments, 2013Scattering-type scanning near-field optical microscopy (s-SNOM) provides few nanometer optical spatial resolution and is compatible with nearly any form of linear and nonlinear optical spectroscopy. We have developed a versatile s-SNOM instrument operating under cryogenic and variable temperature (∼20–500 K) and compatible with high magnetic fields (up

Mid‐infrared scanning near‐field optical microscope resolves 30 nm
Journal of Microscopy, 1999We explore the performance of a scanning near‐field infrared microscope, which works by scattering tightly focused CO2 laser radiation (λ = 10 μm) from the apex of a metallized atomic force microscope tip. The infrared images of test samples prove a spatial resolution of 30 nm and are free of topographical and inertial artefacts, thus they should be of

Optical constants from scattering-type scanning near-field optical microscope
Applied Physics Letters, 2021Scattering-type scanning near-field optical microscopy (s-SNOM) allows for the characterization of optical properties of samples at the nanoscale, well below the diffraction limit of the interrogating wavelength. Typically, it relies on a model for the probe-sample interaction to extract complex optical constants of the sample.

Near field scanning optical microscope for biological applications
Laser Applications to Chemical, Security and Environmental Analysis, 1996In our biophysical laboratory systematic investigations of plague and choler microbes are carried out by different methods (conventional electron microscopy, scanning tunneling microscopy and atomic force microscopy). At present for the investigations we have develop a near field scanning optical microscope (NSOM).

KRIOSBOM101 low-temperature scanning near-field optical microscope
Bulletin of the Lebedev Physics Institute, 2010An optical scanning near-field microscope was developed. A cryostat for obtaining low temperatures in the range of 1.8–300 K was designed. The microscope control unit and software were advanced taking into account the temperature range. A room-temperature measurement technique was refined on test aluminum gratings on glass with a period of 4 µm.

A storage Dewar near-field scanning optical microscope
Ultramicroscopy, 2000A near-field scanning optical microscope for operation within a storage Dewar is described. It was designed for studies of opaque samples and operates in the collection mode. Illumination can be either through the tip or from the side via a separate fiber. Scans can be begun within 2 h after start of cooldown.

Micromachining of diamond with a near-field scanning optical microscope
Optics Letters, 2001Direct-write laser micromachining of diamond on a submicrometer scale with a near-field scanning optical microscope with an uncoated tapered fiber tip has been demonstrated. Micromachined structures can be imaged in situ immediately after modification of the sample.
