scanning near-field optical microscopy (snom) is a member of scanning probe microscopes (spms) family which enables nanostructure investigation of the surfaces on a wide range of materials. in fact, snom combines the spm technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. in this paper, a qualified overview of ...

Instead of forming an entire image at one instant, a scanning optical microscope (SOM) scans a beam of light across specimen in a regular pattern, or raster, and forms its image point by point. A point of light is focused to a diffraction-limited spot on the sample by the objective lens. An image is built up point by point by a detector, either below the slide (if the microscope is exclusively ...

Introduction The optical components of a microscope are its two imaging lenses (eyepiece and objective) and a condenser lens. The eyepiece and objective are responsible for magnifying the image of the specimen and projecting it onto the viewer’s retina or onto the film plane in a camera. The job of the condenser lens is to focus a cone of incident light onto the specimen. To provide the inciden...

OBJECTIVE To introduce the use of optical coherence tomography with an operating microscope for intra-operative evaluation of the human larynx. METHODS A specially equipped operating microscope with integrated spectral domain optical coherence tomography apparatus was used during microlaryngoscopy. RESULTS Technical improvements in optical coherence tomography equipment (e.g. pilot beam, va...
