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 ...

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 ...

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, ...

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 ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

(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 ...
