Fifteen years ago, physicists worked out a method to increase image contrast by hitting the electron imaging beam with an ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

Phase contrast microscopy has played a central role in the development of modern biology, geology, and nanotechnology. It can visualize the structure of translucent objects that remains hidden in ...

Installed in a custom Titan Krios, the laser phase plate enhances motion correction, early‑frame recovery, and 3D classification and alignment.

Typically in optical microscopy, the signal-to-noise ratio (SNR) is calculated to quantify the image contrast which indicates how well different regions of interest in the image can be differentiated.

The invention that first enabled researchers to see clear images of living cells was the phase-contrast microscope, which won its inventor, Frits Zernike, a Nobel Prize in 1932. Prior to Zernike's ...

A new purpose-built microscope has been developed that uses the complex properties of UV light to improve image resolution and contrast. Most cells are transparent at visible wavelengths, which means ...
