A tiny bubble of graphene could be used to make an optical lens with an adjustable focal length. That is the claim of physicists in the UK, who have shown that the curvature of such bubbles can be ...
In this video, we dive into how a converging lens forms images! From understanding focal points to real and virtual images, we break down the physics behind lens formation with easy-to-follow ...

For more than a century, photographers have had to choose which part of a scene should be tack sharp and which parts would ...
The idea of having images and text streamed live across your contact lenses has been used in many a Hollywood film. Now an international team of researchers has developed the first working prototype ...
Contact lenses get pretty thin nowadays, but they’ve got nothing on a new lens from scientists at Stanford and the University of Amsterdam. The team has created the world’s thinnest lens, measuring ...
John Pendry is a physicist at Imperial College London who laid the theoretical foundations for the invisibility cloak and superlenses capable of producing the sharpest ever images. He talks about the ...
