The resolution limit refers to the smallest detail that can be distinguished in an imaging system, beyond which objects appear as a single point rather than separate entities. In the context of superlenses, this concept is crucial because it highlights how these advanced optical devices can surpass traditional diffraction limits, enabling the observation of finer details than what standard lenses allow. Understanding the resolution limit helps in appreciating the potential applications of superlenses in fields like microscopy and photonic devices.
