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 ...

Schematic of the transmission mode microsphere superlens integrated with a classical optical microscope. The spheres collect the near-field object information and form virtual images that can be ...

Measuring the volume, motion and contents of microscopic droplets is important for studying how airborne viruses spread (including those that cause Covid-19), how clouds reflect sunlight to cool the ...

(Nanowerk Spotlight) Direct visualization and manipulation of individual carbon nanotubes (CNTs) in ambient conditions is of great significance for their characterizations and applications. However, ...

New work enables optical microscopes to measure these nanometer-scale details with a new level of accuracy. Over the last two decades, scientists have discovered that the optical microscope can be ...

X-ray microscopes are commonly used in combination with full-field imaging techniques in spectromicroscopy applications, where they allow the chemical structures of materials to be analyzed and ...

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 ...

The techniques used in optical microscopy are important to ensure that a sample can be viewed as clearly as possible. This will provide information about its microscopic appearance. An optical ...

Fluorescence imaging can reveal details of neuronal activity in sections of the spinal cords of animals, but collecting data from living subjects can be challenging. Developments in micro-optics ...

Widely considered the most common type of microscope, Optical Microscopes magnify visible light to allow for the examination of features too small for the naked eye. This kind of microscope is ...
