It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next ...

Discover how to transform a basic webcam into a powerful DIY microscope using simple materials. In this step-by-step tutorial ...

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 ...

Optical microscopes typically max out at anywhere between 500x to 1,500x magnification, at which point you need to switch to a scanning microscope to zoom any closer. They come with some functional ...

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 ...

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 ...

This effect is used in simple microscopes, which consist of a single lens that images a sample held clamped into a frame and illuminated from below, as is shown in Figure 2. This type of microscope ...

(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 ...

Light microscopy is used to make small structures and samples visible by providing a magnified image of how they interact with visible light, e.g., their absorption, reflection and scattering. This is ...

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 ...
