Raman microscopy combines optical microscopy with the ability to determine the chemical makeup of surfaces. Laser light is delivered to the sample surface via the same objective as the optical light ...

Researchers from the Physical Chemistry and Theory departments at the Fritz Haber Institute have found a new way to image layers of boron nitride that are only a single atom thick. This material is ...

The study of biological systems varies from whole organisms, organs, and organoids, down to their building blocks of proteins and cells. At the lower end of the scale, atomic force microscope (AFM) ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

A key limitation of microscopes is that they can only image objects or details that are half the wavelength of the light used – so for optical microscopes, details can be seen down to about 200 ...
