Flat lenses offer a way to minimize the optical aberrations and astigmatisms that conventional spherical lenses can be prone to, and can potentially open up new applications that traditional lens are ...

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 ...

The imaging resolution has long been constrained by the Abbe-Rayleigh diffraction limit. While the 2014 Nobel Prize recognized fluorescence microscopy, achieving single-shot, label-free far-field ...

With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the ...

Edmund Optics' TECHSPEC MWIR (midwave infrared) achromaticlenses can be used by designers and researchers working in the 3-µm to 5-µmspectral region. Providing near-diffraction-limited performance, ...

To design and improve energy storage materials, smart devices, and many more technologies, researchers need to understand their hidden structure and chemistry. Advanced research techniques, such as ...

US engineers have succeeded in creating a near-perfect ‘superlens’ that uses the principles of metamaterials to overcome conventional diffraction limits. The lenses could be used in ...

DigiLens, of Sunnyvale, California, US, has developed a liquid crystal-based lens that provides customized diffraction gratings depending on which of its layers are 'switched on'. The application ...

(Nanowerk News) To design and improve energy storage materials, smart devices, and many more technologies, researchers need to understand their hidden structure and chemistry. Advanced research ...

Researchers have developed a new and improved version of electron diffraction that offers advanced and unique experimental instrumentation for studying particle acceleration to researchers from all ...
