Scanning Near field Optical Microscope
scanning probe microscopy (SPM) methods have produced the necessary tools for a step forward in optical measurements. The possibility to go beyond the Abbe diffraction limit has been achieved with the Near- field light optical microscopes (SNOM). They employ SPMs precision of piezoelectric raster-scanning together with sharp probes to obtain light optical images at subwavelength resolution.
