How is Near-field Scanning Optical Microscopy (NSOM) Different from Traditional Optical Microscopy?
NSOM overcomes the diffraction limit of traditional optical microscopy by using a sharp tip to scan the surface of a sample at a very close distance. This allows for a resolution beyond the wavelength of light, enabling detailed imaging at the nanoscale. NSOM is particularly useful for studying the optical properties of nanostructures and nanomaterials with high spatial resolution.
