Abstract
The submicron size doughnut shape focal spot, which is traditionally measured by scattering off a nanoparticle or a fluorescent bead, is measured for the first time by a near-field scanning optical microscopy (NSOM) fiber probe. Measurement results agree very well with calculations. This method offers superior repeatability, better control and is less time-consuming than the traditional method as the probes are mechanically protected by their insertion into fiber optic ferrules, which also greatly facilitates the alignment of the tip to the focal spot.
