For centuries, telescopes have relied on curved lenses and mirrors to observe the Universe. A team of researchers has recently developed a flat, lightweight lens capable of capturing precise color ...

In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.

For the first time, a flat telescope lens has been produced that represents colors accurately, offering a way to make less bulky lenses that could be sent into space cheaply. The first telescopes ...

Enter Rajesh Menon and his team at the U. Their new flat lens offers the same light-bending power as traditional curved lenses while avoiding the color distortions of FZPs. "Our computational ...
