Abstract
We report a hybrid microscope composed of an apertureless scanning near-field optical microscope and a commercial atomic force microscope. We discuss the optical origin of the near-field images of a test sample. We show that the optical images have a sharp contrast that depends on the illumination parameters: the state of polarization and the angle of incidence of the incident light.Keywords
