Researchers designed, implemented, and applied a new and improved focusing system for electron diffraction measurements.

Optical lenses are limited by the nature of light — the so-called diffraction limit — and do not generally allow visualisation of objects smaller than 200 nanometres across, about the size of the ...

From there, a special diffraction lens can be built. The diffraction lens can be shaped into any pattern with a small amount of computer code to compute the diffraction pattern for a given image.

Flat lenses offer route to diffraction-limited imaging 19 Aug 2020 New manufacturing method uses femtosecond laser to create surface structures on monolayers.

One of the key obstacles in advances in optical microscopes is the lens or, more precisely, the diffraction limit, which is the theoretical limit of the resolution of a particular lens.

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, ...

Historical Archive Electrically switchable lens exploits holography and diffraction 17 Jun 2002 DigiLens, of Sunnyvale, California, US, has developed a liquid crystal-based lens that provides ...

But, like with telephoto lenses, diffraction may come into play, which is especially true when using a teleconverter.

When light passes through a lens, the light gets spread out through diffraction. This means that two objects ... molecule is located—and reconstruct a high-resolution image of the sample. Another ...

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