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 ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The new microscope uses a 405 nm laser—the same wavelength ...

Electrical engineers at the University of California San Diego developed a technology that improves the resolution of an ordinary light microscope so that it can be used to directly observe finer ...

The development of STED microscopy has allowed researchers at the Max- Planck Institute for Biophysical Chemistry to image, for the first time, proteins from single synaptic vesicles, answering ...

Researchers have demonstrated a quantum microscope that can break through a fundamental barrier faced by regular microscopes and see tiny structures that are normally invisible. The device “squeezes” ...

The M25 multi-focus microscope uses separate cameras to capture images from 25 focal planes at different depths in a sample. (Photo by Eduardo Hirata) The aberration-corrected multi-focus microscopy ...
