The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) say that they have built a thulium fiber laser capable of emitting 1.91 kW - nearly double the typical output ...
