100% reflection free 'glass' unveiled in Japan
Light is reflected when it strikes a surface of higher refractive index. Diamonds sparkle because they have a very high refractive index.

Unlike conventional multi-coating technology which reduces reflections, this new discovery by Japanese company Riken's Nanophotonics Laboratory uses rare metals such as gold and silver to take advantage of an optical phenomenon discovered by Sir David Brewster in 1815.

Prisms, called 'meta-material prisms,' are composed of transparent solid material like glass in which nano-meter sized coil of rare metals are processed and integrated. The technique which has been described by the company as 'opposing to common sense of optics' reduces the refractive index at the boundary between air and the material. Reflections are eliminated as a result.

The research company expect this technique to 'open a new age to develop new optical appliances'. Non reflective glass could allow for complicated multi-element lens designs that do not suffer from any ghosting or flare, with increased light transmission.

Details of the discovery can be found on the Riken website here (translated page)

Yeah, I was wondering what a Leica Noctilux-M f1.0/50 would cost if made of this stuff.. Wink

How much and how long does it cost to manufacture a Super-UD element???

Gold is NOT the rarest material.....

yea, Francium is, only about 20 atoms in the whole world at anyone time.

but it would be useless in glass, way to reactive.

Great! Some more letters to add to the already comical alpha-betty-spaghetti of lens nomenclature. Especially if they combine elements made in this stuff with conventional elements.

Roll on the Nikon AF-S 14-300mm IF ED M-N VR G DX!
