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 ...

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 ...

(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 ...

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 ...

GLONIK has released a new 3D optical microscope that allows users to freely change their views, not only vertical view but also oblique views at arbitrary angles. GLONIK's patented technology provides ...

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 ...

A single flat metalens now handles both excitation and fluorescence collection for diamond quantum sensors, enabling nanoscale sensing in spaces too tight for conventional optics. (Nanowerk Spotlight) ...

Super resolution: image taken using the new chip. (Courtesy: Bielefeld University / Robin Diekmann) A photonic chip that allows a conventional microscope to work at nanoscale resolution has been ...

Since the invention of the optical microscope in the 17th century, a remarkable evolution can be observed in the microscope’s performance and diversity. On the other hand, if we focus on its structure ...
