Publications of the Astronomical Society of the Pacific, Vol. 120, No. 866 (11 April 2008), pp. 430-438 (9 pages) ABSTRACT.Filled arrays of bolometers are currently being employed for use in astronomy ...

(Nanowerk News) Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see fact box), except when using metal ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

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 ...

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, ...

The Abbe diffraction barrier, which fundamentally restricted the lateral optical resolution to 200 – 300 nm until the early 1990s, can be overcome by super-resolution optical fluorescence imaging ...

I seem to be writing about microscopy fairly often these days. First there was the article about a new technique that was able to resolve features smaller than that allowed by the diffraction limit.

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

Two groups of researchers have shown that the minimum size of a laser need not be restricted by the wavelength of light it emits, provoking a rethink of what optics and lasers can do at the nanoscale.

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 ...
