Optical microscopes depend on light, of course, but they are also limited by that same light. Typically, anything under 200 nanometers just blurs together because of the wavelength of the light being ...

Blurry light from lens imperfections is a problem everywhere, from microscopes to telescopes to smartphone cameras. Using a ...

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 ...

The demand for disposable miniature imaging platforms (DMIPs) is growing rapidly. Used for commercial, scientific, medical, and educational purposes, DMIPs have numerous applications but can be ...

In the field of materials characterization, optical microscopy is one of the most commonly used imaging techniques. It is estimated that the diffraction limit of optical light is half of the ...

Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle. Measuring the volume, motion and contents ...

This article discusses how optical microscopy is used in analyzing, visualizing and imaging nanomaterials as well as its limitations and recent studies related to optical microscopy utilization in ...

A new imaging technology uses polarized 'optical vortices' to provide a detailed, dynamic view of molecules in motion. Understanding the nitty gritty of how molecules interact with each other in the ...
