A new type of flat, ultrathin lens designed to be free of chromatic aberrations has been developed by researchers in the US. The device has a variety of potential applications, from ultralight imaging ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers now present a new technology for making the artificial materials ...

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.

Ultra-thin flat lenses suitable for photography are one step closer after a team of researchers at Harvard University made a major leap forward with its prototype wafer-thin flat lens. The new lens ...

Traditional cameras—even those on the thinnest of cell phones—cannot be truly flat due to their optics: lenses that require a certain shape and size in order to function. At Caltech, engineers have ...

A new generation of optical lenses is being developed and tested at multiple universities and companies worldwide. These lenses, known as metalenses, are silicon films a thousand times thinner than a ...

We compare and contrast concave and convex lenses by drawing ray diagrams. In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and ...

Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a prism, a ...
