A remarkable crystal called molybdenum oxychloride could help make futuristic technologies like smart contact lenses and ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.

For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be, the ...

(Nanowerk Spotlight) Conventional lenses made of glass can only focus light in a limited way, restricting many potential applications in optics and photonics. Now researchers have developed a new type ...

In antiquity, we see examples of magnifying crystals formed into a biconvex shape as early as the 7th century BC. Whether the people of that period used them either for fire-starting purposes or ...

Our eyes take in the dazzling greens of dense forests, blues of alpine lakes, and reds and purples of sunset. Yet there’s an entire world hidden from sight. Our eyes only perceive a narrow sliver of ...
