Phase-contrast microscopy articles from across Nature Portfolio. Atom; RSS Feed; Definition. Phase contrast microscopy is a white-light optical microscopy technique that relies on sample-induced ...

To avoid this restriction, which is known as vignetting, Cui explains that the team separated the two lenses and inserted a Keplerian telescope between them. “This ‘telescope-within-a-microscope’ ...

Microscope resolution with ultraviolet light. UV microscopy uses UV light as the source for the microscope, rather than visible light. UV light has a wavelength between 180 and 400 nm, which is ...

Over the years, new technologies—from incorporating pinholes into light paths to gene editing samples for fluorescence expression—have allowed researchers to push the bounds of light microscopy.

Screenshot of the Zygo white light interferometry microscope software. (Credit: Huygens Optics) White light interferometry (WLI) is a contact-free optical method for measuring surface height.

The team reported on the method in Nature, in a paper titled “Light-microscopy-based connectomic reconstruction of mammalian brain tissue,” in which they stated, “Here we present a ...

Light microscopes use light and mirrors and can see things as small as 400 nanometers. ... Here's an amoeba engulfing red blood cells and red and white blood cells moving through a tiny blood vessel.

An artist's representation of the new Brillouin microscopy approach that allows entire light-sheets to interact with 3D biological samples. The scattered light reveals a unique optical ...

Scientists turn to light microscopy when imaging cells, organelles, and subcellular structures and molecules. Scientific breakthroughs gave rise to brightfield methods that became indispensable tools ...

When backlit with a white light, the mostly transparent ghost catfish becomes iridescent. Microscopic striped structures in the fish’s muscles diffract the light, separating it into different ...

Large-scale microscopy combined with tissue clearing and expansion enables nanoscale imaging of centimeter scale specimens.

Scientists developed a new microscope based on Brillouin scattering -- a phenomenon where light interacts with naturally occurring thermal vibrations within materials, from which their mechanical ...
