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 ...

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, ...

When measuring with light, the lateral extent of the structures that can be resolved by an optical imaging system is fundamentally diffraction limited. Overcoming this limitation is a topic of great ...

To unravel the complexities of biological phenomena, scientists have long relied on microscopy to visualize the intricate details of their specimens, including tissue architecture, cell morphology, ...

You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, while X-rays reveal its internal structures and infrared captures a ...

A “superlens” that refracts light in unconventional ways to let an optical microscope see beyond the normal limit of its vision has been created by US researchers. They hope to develop a cheaper, mass ...

Modern microscopes opened up the world of the minute to an amazing degree, allowing people to see all the way down to a bacterium wriggling on a slide. But if you want to see down even smaller in ...

There’s a mistake people often make when assessing the performance of a microscope or telescope— forgetting the diffraction limit. It is a theoretical limiting factor governing the maximum obtainable ...

Microscopes are good, but not that good. The view through them gets prohibitively fuzzy when you try to look at things smaller than half the wavelength of the light used for imaging; for visible light ...

Newswise — Ever since Antonie van Leeuwenhoek discovered the world of bacteria through a microscope in the late seventeenth century, humans have tried to look deeper into the world of the ...
