  1. superlensnoun

    Any of several lenses, often built using material with negative refractive index, that can resolve images having dimensions less than that of the wavelength of light used


  1. Superlens

    A superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit. For example, in 1995, Guerra combined a transparent grating having 50nm lines and spaces (the "metamaterial") with a conventional microscope immersion objective. The resulting "superlens" resolved a silicon sample also having 50nm lines and spaces, far beyond the classical diffraction limit imposed by the illumination having 650nm wavelength in air. The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution depending on the illumination wavelength and the numerical aperture NA of the objective lens. Many lens designs have been proposed that go beyond the diffraction limit in some way, but constraints and obstacles face each of them.


  1. Superlens

    A practical superlens, super lens or perfect lens, could significantly advance the field of optics and optical engineering. The principles governing the behavior of the superlens reveals resolution capabilities that go substantially beyond ordinary microscopes. As Ernst Abbe reported in 1873, the lens of a camera or microscope is incapable of capturing some very fine details of any given image. The super lens, on the other hand, is intended to capture these fine details. Consequently, conventional lens limitation has inhibited progress in certain areas of the biological sciences. This is because a virus or DNA molecule is out of visual range with the highest powered microscopes. Also, this limitation inhibits seeing the minute processes of cellular proteins moving alongside microtubules of a living cell in their natural environments. Additionally, computer chips and the interrelated microelectronics are manufactured to smaller and smaller scales. This requires specialized optical equipment, which is also limited because these use the conventional lens. Hence, the principles governing a super lens show that it has potential for imaging a DNA molecule and cellular protein processes, or aiding in the manufacture of even smaller computer chips and microelectronics.
