A compound microscope uses two lens systems in series — an objective that forms a magnified real image, and an eyepiece that magnifies that image again — which is what separates it from a simple ...

As a mouse explores its environment, millions of neurons across the brain fire in sync. To study only a small subsection at a time would be to miss the forest for the trees, but powerful microscopes ...

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

A team of scientists in the lab of Changhuei Yang at Caltech has developed an inexpensive, robust method for autofocusing microscopes that involves little more than a couple of LED lights and some ...

Brief history of microscopy -- Definitions, attributes of visibility and general principles -- Simple and compound light microscopes -- Compound microscopes using reflected light -- Microscopy with ...

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments. As a mouse explores its ...
