Biomedical Optics & Medical Imaging: Far-field superlens imaging at visible wavelengths

Abstract:
Adding a special lens between an object and a conventional optical microscope can improve image resolution to below the diffraction limit at visible wavelengths.

The optical microscope is one of the most important and widely used imaging tools due to its noninvasive nature, low cost, and versatility. But despite its remarkable achievements in the history of science and technology, the conventional optical microscope is generally not considered a competent nanoscale imaging apparatus because its spatial resolution originates from the diffraction of light and is limited to a few hundred nanometers. Therefore, the development of an optical microscope that circumvents the diffraction limit and can fulfill the demands of modern nanotechnology is widely desired.
