Surface chemical analysis. Scanning-probe microscopy. Definition and calibration of the lateral resolution of a near-field optical microscope1 Scope This International Standard describes a method for determining the spatial (lateral) resolution of an apertured near field scanning optical microscope (NSOM) by imaging an object with a size much smaller than the expected resolution. It is applicable to aperture type NSOMs operated in the transmission, reflection, collection or illumination collection mode.
