Abstract:	An evanescent field optical microscope (EFOM) is presented which employs frustrated total internal reflection on a localized scale by scanning a dielectric tip in close proximity to a sample surface. High resolution images of dielectric gratings and spheres containing both topographic and dielectric information have been obtained. The resolution obtained is 30 nm in the lateral directions and 0.1 nm in height depending on proper tip fabrication
