A superlens, or super lens, is a lens which uses metamaterials to achieve super-resolution imaging and go beyond the diffraction limit. The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their image resolution depending on the radiation wavelength and the numerical aperture (NA) of the objective lens.
