This actually sounds both revolutionary and immediately practical for lens design. Covering lens with gold nano antennae sounds expensive, and I assume the surface is delicate, but thin spectacle lenses and super lightweight camera lenses are an obvious result.
- andrewcooke 15y agoabsolutely. you could make much more compact "telephoto" lenses too. or connect "bifocals" to the nerve that controls eye focussing and have glasses that automatically focus to the correct distance (yes, i am getting old). or stationary solar collectors that adjust to the moving sun (or that still move but self-correct for distortions and support flexure). or a new kind of electronic ink. or... this is huge, yet the report covers just silly mirrors... weird.
- Someone 15y agoMany of those ideas require not only that we can make this stuff in bulk at low prices, but also that we can dynamically change the stuff after production at high speed. I did not read that in the article. Did I browse it too fast?
- andrewcooke 15y agoah. maybe i misread the article. where it says antennas i assumed they were active. but if they're just passive (conductive) elements then you're right. i guess that is more likely :o( [edit:] that would certainly explain why they only mentioned silly mirrors!
- Tloewald 15y agoThe lenses can be passive and thin, which is all you need to make camera or spectacle lenses.
