Geometrical optics, a branch of optics that eschews wave phenomena in favour of ray propagation, continues to underpin advances in lens design and optical engineering. Contemporary studies in this ...

Researchers have developed a new plug-and-play device that can add adaptive optics correction to commercial optical microscopes. Adaptive optics can greatly improve the quality of images acquired deep ...

It’s not uncommon to see patented products never make it off paper. But if Canon’s latest lens patent is anything to go by, Canon could soon have one of the most impressive super-telephoto lenses on ...
