We present a novel technique in which a reflection scanning near-field optical microscope (SNOM) is used for direct writing of nano-scale patterns into hydrogen-passivated silicon surfaces. The reflection SNOM is operated as a combined shear-force/near-field microscope enabling simultaneous imaging of topographical and optical properties with subwavelength resolution. ... Beside high resolution optical imaging (<50 nm) and patterning of hydrogen-passivated silicon surfaces, the SNOM can also be used for transferring nano-scale patterns into ordinary photo resist with a typical resolution of 50-100 nm. The SNOM thereby overcomes the far-field diffraction limit of conventional photolithography.  5, record 1, English, - scanning%20near%2Dfield%20optical%20microscope

Near-field scanning optical microscope [...] In this case the standard AFM [atomic force microscope] cantilever is replaced by something that can act as a waveguide for light (typically an optical fibre). Light is passed through the waveguide onto the sample and resulting light is detected via various means ...  3, record 1, English, - scanning%20near%2Dfield%20optical%20microscope

Microscope optique à balayage à champ proche. Il est possible d'éviter la limitation de résolution due aux conditions d'Abbe pour caractériser plus finement la microgéométrie de surface. Grâce à une fibre optique, on éclaire la surface par un très fin pinceau en incidence évanescente et l'on recueille la lumière diffractée; en balayant la surface on construit ainsi une image point par point.  1, record 1, French, - microscope%20optique%20%C3%A0%20balayage%20%C3%A0%20champ%20proche

[...] a principios de 1980 se inventó el microscopio óptico de barrido de campo cercano (SNOM o NSOM), en el que una fuente de luz nanoscópica, generalmente una punta de fibra óptica con una apertura más pequeña de 100 nm, barre la superficie de la muestra en la región llamada "campo óptico cercano".  2, record 1, Spanish, - microscopio%20%C3%B3ptico%20de%20barrido%20de%20campo%20cercano

Estos microscopios rastrean la muestra mediante un haz de luz que se emite (o se recibe, según el diseño) a través de una pequeña abertura situada en el extremo de la punta de la sonda, que no es más que una pequeña fibra óptica cubierta de un metal que refleja la luz y evita pérdidas. El diámetro de la abertura y la distancia sonda-muestra tienen dimensiones similares e inferiores a la longitud de onda de la luz que se emplea.  3, record 1, Spanish, - microscopio%20%C3%B3ptico%20de%20barrido%20de%20campo%20cercano

SNOM is the acronym for "scanning near-field optical microscopy," an alternative name for NSOM (near-field scanning optical microscopy). The basic principle of such a kind of technique is quite simple: light passes through a sub-wavelength diameter aperture and illuminates a sample that is placed within its near field, at a distance much less than the wavelength of the light. The resolution achieved is far better than that which conventional optical microscopes can attain.  4, record 2, English, - scanning%20near%2Dfield%20optical%20microscopy

Microscopists are now in a position to transfer the refinements of the past 100-year techniques for enhancing contrast and highlighting specific features, such as polarization contrast, immunofluorescence and phase contrast to scanning near-field optical microscopy. With existing scanned-probe microscopes we can "see" the nanometer realm of molecules and microcircuits. As the same technology is applied to optical microscopy, we may eventually come to see that world in the familiar terms of light, shadow and color.  6, record 2, English, - scanning%20near%2Dfield%20optical%20microscopy

Ces interactions se produisent à l'échelle moléculaire, c'est pourquoi il est très important d'analyser les propriétés physico-chimiques de la surface à l'échelle atomique et moléculaire. Pour ce faire nous utilisons dans notre groupe les techniques de microscopie à champ proche à balayage : microscopie à effet tunnel (STM), microscopie à force atomique ou effet de force (AFM-SFM), microscopie optique à champ proche à balayage (SNOM).  1, record 2, French, - microscopie%20optique%20%C3%A0%20champ%20proche%20%C3%A0%20balayage

L'équipe [...] a réussi à visualiser ce phénomène biologique en recourant à la microscopie optique à balayage à champ proche (NSOM). Cette technologie d'imagerie éclaire la cellule en canalisant la lumière dans une sonde à fibre optique plus petite qu'un micron. La minuscule ouverture de la sonde (guère plus de 50 nanomètres de diamètre) interdit la diffraction des rayons lumineux qui réduit normalement la résolution en microscopie classique.  3, record 2, French, - microscopie%20optique%20%C3%A0%20champ%20proche%20%C3%A0%20balayage
