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 ...

For hundreds of years, the optical microscope was the only tool available to scientists wanting to study the movement of cells, bacteria and yeast. But the diffraction of light made it impossible to ...

Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Each time you move the ...

A project at Duke University has demonstrated how commercial AI models could accelerate microscopic examination of 2D materials and analysis of the results. The Duke Lab of Haozhe "Harry" Wang has ...

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 ...

Researchers have developed a new microscopy method that uses a magnetic field and polarized light to provide quantitative measurements that could enable faster and more objective detection of malaria ...

When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic ...

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 ...
