Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

In a new study, researchers at the Indian Institute of Science (IISc) show how a brain-inspired image sensor can go beyond the diffraction limit of light to detect miniscule objects such as cellular ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

Standard optical microscopes have surrendered their once dominant position at the forefront of scientific research to more advanced tools. As we delve deeper into the microscopic world, photons just ...
