Scanning Probe Microscope Solver SNOM
Scanning Near-Field Optical Microscopy (SNOM) is one of a number of types of Scanning Probe Microscopy (SPM). This is very powerful modern technique for surface investigation, which can provide the resolution about 50 nm. This resolution is much better than the max. standard optical resolution (500 nm) due to so-called near-field effect. The main idea of SNOM is to measure the light intensity within the distance about 10 nm (much smaller than the wavelength of light) from the sample with the very diminutive probe (sharpened optical fiber tip). This method allows to obtain data of optical properties of the sample surface, to make nanolithograthy, to measure local spectrum on the surface (e.g. quantum dots spectrum), to control the quality of optical surfaces (e.g. mirrors, lens, prisms, splitters etc.), to measure local fluorescence, to obtain the distribution map of light intensity on semiconductor samples. Solver SNOM system is based on inverted optical microscope and with additional measuring heads is easily transformed to Solver BIO model that is widely used for biological applications.
