This invention is a super-resolution optical cover glass slip or mount which can resolve the optical information on a sample surface without diffraction limit. This super-resolution optical cover glass slip or mount is a multi-layered body at least comprising: (a) a substrate of transparent material; (b) a first protective and spacer layer formed on one surface of the substrate, which is made from transparent dielectric material; (c) a nano structure thin film which is capable of causing localized non-linear near-field optical interaction; (d) a second protective and spacer layer formed on the localized non-linear near-field optical interaction layer, which is also made from transparent dielectric material.
