In this article the far‐field radiation analysis of near‐field optical probes is presented. It is shown that the quality of probes used for near‐field scanning microscopy imaging can be estimated using directional measurements of the far‐field radiation patterns. Experimental results are compared with numerical modeling of far‐field radiation performed using finite difference in time‐domain method (FDTD) and with SEM characterization of real probe geometry. The effects of probe geometry on real measurement on different samples are studied as well. Copyright © 2008 John Wiley & Sons, Ltd.
