Schematic of the NSOM. The resolution of the NSOM relies on two key factors: the aperture size of the probe and the distance between the tip and the sample. The probe can perform either as the source (for near-field illumination), as the detector (for collection of the evanescent light scattered by the sample), or both. NSOM, near-field scanning optical microscopy.
