This is useful to understand what the sample looks like and what it is made of, but also allows us to see processes of the microscopic world, such as how substances diffuse across a cell membrane.

Most, but not all, stereo microscopes have two light sources: one above the sample, which is reflected in the eyepieces, and one below the sample for illumination through thinner samples.

Researchers have succeeded in filming the interactions of light and ... Electron microscopes give us insight into the tiniest details of materials and can visualize, for example, the structure ...

Light microscopes are useful for imaging live cells ... a series of random high-resolution speckled patterns. When a sample is mounted on the slide, it gets illuminated in different ways by ...

for example, individual cell processes in living tissue at unprecedented resolutions. The world's most advanced light microscopes allow us to see single molecules, proteins, viruses and other very ...

This tiny microscope, which uses microfluidics to flow a sample over an imaging chip from a digital camera, has the same resolution as a conventional light microscope. The Caltech device uses a ...

Plus, many electron microscopes require the sample to be coated in a thin film ... produced by splitting a single beam of light into two orthogonally polarized beams. These are focused on separate ...
