The Foldscope is constructed out of greeting card paper, a watch battery, and a dirt cheap lens. But don’t be fooled, you can use it to detect more than 20 diseases. Many of the world’s most fatal and ...

Which digital microscopes are best? Whether an academic researcher or a casual hobbyist, the microscope is an essential part of nearly every scientist’s toolkit. While all microscopes let you examine ...

MR. BECK has in this little book collected and set out in elementary form a considerable amount of information useful to the microscopist. The optics of the instrument are described in a simple manner ...

As early as the 4 th century AD, people had discovered the basic concept of an optical lens, and by the 13 th century, they were already using glass lenses to improve their eyesight and to magnify ...

(Nanowerk News) Researchers at the National Institute of Standards and Technology (NIST) and their collaborators have developed a way to retrofit the transmission electron microscope -- a ...

Small modifications to an ordinary optical microscope have helped turn it into a powerful instrument that can be used for studying complex cellular biology in real time at the nanoscale level. And ...

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 ...

Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...

Researchers have developed a way to retrofit the transmission electron microscope -- a long-standing scientific workhorse for making crisp microscopic images -- so that it can also create high-quality ...
