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 ...

Fig. 1: Simplified overview of the optical setup. The rays of the fluorescence particle are refracted by the fluctuating water-air interface. Because this aberrating layer can be considered planar, ...

Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240085 , discusses how cascaded metasurfaces enable adaptive aberration corrections for focus scanning. Optical researchers have ...

Overview of the main types of Scannig Probe Microscope types: Scanning tunneling microscope (STM) – using the tunneling current I between the outermost atom of a conducting probe within an atomic ...

Until today, skin, brain, and all tissues of the human body were difficult to observe in detail with an optical microscope, since the contrast in the image was hindered by the high density of their ...
