Using light to measure ever-smaller objects has been central to progress in many scientific disciplines for centuries. As far back as 1873, German physicist Ernst Abbe proved that light diffraction ...

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 ...

While probing single molecules or atoms typically requires liquid helium—a costly resource—to build a stable environment, a new development from a joint Chinese research team changes the game. By ...

Researchers from the Physical Chemistry and Theory departments at the Fritz Haber Institute have found a new way to image layers of boron nitride that are only a single atom thick. This material is ...

The calibrated optical microscope could then be used to rapidly measure other standards that the researchers fabricated, enabling a statistical analysis of the accuracy and variability of the process.

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical “hotspot” of a ...

Researchers have shown that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. Researchers at the University of Illinois at ...

For over a century, light has both helped and limited our view of the tiny world. Microscopes use light to magnify cells, microbes, and nanomaterials—but light also behaves like a wave, and waves ...
