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 ...

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 ...

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 ...

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 ...

Some time before 1668, Antony van Leeuwenhoek learned to grind lenses and make simple microscopes. Scientists have been looking through different versions of this imaging system ever since. There’s ...

Henry Baker drew this illustration of van Leeuwenhoek's microscopes in 1756. __1683: __Anton van Leeuwenhoek writes a letter to Britain's Royal Society describing the "animalcules" he observed under ...

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 ...

Microscopes have been fine-tuned to image cells in granular detail, with the most sophisticated instruments capable of resolving individual atoms within a protein. The expense of microscopes creates ...
