The optical microscope is a critical equipment for scientific research and failure inspection in high precision industries. However, for centuries, the imaging resolution of microscopes is fundamentally limited by the diffraction limit of light. Existing efforts to break this fundamental diffraction limit through various technologies suffer from limitations such as a near-field operation, which requires the sample to be close to the microscope, or the dyeing of samples, which is an invasive process that affects the quality of the sample.
