KitGuru highlights the discovery of meta-material lenses, a new lens design made up of thousands of microscopic tower-like structures made of titanium dioxide. Each tower is capable of splitting and refocusing the light that hits them, and by arranging them in a specific pattern they can refocus all of the light on a single point, making them an effective lens.
There are several benefits to this technology, it promises the creation of lenses that are not only higher in quality but also much smaller than traditional lenses. Furthermore, the creation of a meta-lens is reportedly very easy and could be done in semiconductor fabs.
Better yet, making this sort of meta-lens is incredibly easy. It might sound like a complicated process, but compared to the physical grinding and polishing of traditional lenses it’s much easier. It’s even compatible with fabrication plants currently producing silicon chips and other electronics, so mass production of these lenses could begin far quicker than you might have expected.
This could allow for not only much smaller VR headsets in the near future, but higher grade lenses for cameras, microscopes and telescopes, all in much, much smaller form factors than have ever been possible with traditional glass lenses.
