Superlenses are advanced optical devices that can surpass the diffraction limit of traditional lenses, allowing them to focus light beyond the usual constraints. This capability enables them to produce images with much higher resolution, making them valuable in fields like microscopy and imaging technology. These lenses often utilize materials with unique properties, such as metamaterials, which can manipulate light in unconventional ways. By bending light around objects, superlenses can reveal details that are typically invisible to standard optical systems, opening new possibilities in scientific research and medical diagnostics.
