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 ...

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 ...

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

Plan-apochromat microscope objectives set the benchmark for precise, high-resolution imaging with exceptional color accuracy. By correcting chromatic and spherical aberrations while maintaining a flat ...

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 ...

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 ...

Microscopes are of three basic types: optical, electron (or ion), and scanning probe. The modern optical or light microscope was developed in the mid-19th century. Optical microscopes use transparent ...

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 ...

Left, a tissue sample dyed by traditional methods. Centre, a computed stain created from infrared–optical hybrid imaging. Right, tissue types identified with infrared data; the pink in this image ...

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 ...
