It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Planar super-oscillatory lens (SOL), a far-field subwavelength-focusing diffractive device, holds great potential for achieving sub-diffraction-limit imaging at multiple wavelengths. However, ...

The complexity and cost of a scientific instrument have a large impact on the number of scientific teams with access to the instrument for their research 1,2 and thus to which extent a microscope ...

A: The resolution of an instrument that uses light to see things can’t improve beyond a point. This is called the diffraction limit. The resolving ability of, say, a telescope says how well it can ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

Recent scientific advancements have opened new opportunities for the close observation of physical phenomena. Researchers at University of Cambridge and University of Newcastle recently introduced a ...

What is Single-Molecule Localization Microscopy? Single-molecule localization microscopy (SMLM) is a super-resolution imaging technique that enables the visualization of biological structures and ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, ...

Researchers from the University of Science and Technology of China (USTC) led by Prof. ZHANG Douguo have unveiled a planar optical device that significantly enhances the capabilities of dark-field ...

The printable resolution is visible lightDiffraction limitIts value is determined by about 100,000 dpi. However, with such a method of blending a large number of dyes, this limit can not be reached ...
