For centuries diffraction limited the resolution of optical microscopy. The past 50 years have, however, seen one limitation after another buckle under the ingenuity of a host of wide-ranging ...

In the field of materials characterization, optical microscopy is one of the most commonly used imaging techniques. It is estimated that the diffraction limit of optical light is half of the ...

Optical microscopes have for a long time played a vital role in biomedical research. Their ability to provide multidimensional structural and functional information about a specimen in a non-invasive ...

Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.

Introduction to SNOM: The Scanning Near-field Optical Microscope (SNOM) stands as a pivotal analytical tool in nanotechnology, enabling the visualization of nanostructures with resolution beyond the ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Input and modulation of many different parameters are essential for other competitive ‘single measurement mode’ methods to produce better results on various surface textures in the same field of view ...

Optical non-contact profilers are interference microscopes used to accurately measure the three-dimensional height variations on surfaces of a given test material. Optical profilers manipulate the ...

A new optical measuring device offers a cheaper, quicker alternative to confocal microscopy. Researchers at the Fraunhofer Institute for Production Technology (IPT) have developed a prototype optical ...

Distance markers: Polyprolines are relatively stiff polypeptides that can be used as intramolecular “rulers” to demonstrate MINFLUX optical resolutions. This image shows optically measured distances ...

Computational fluorescence microscopy (CFM) requires accurate point spread function (PSF) characterization for high-quality ...
