Exceptional points (EPs) are non-Hermitian singularities where two or more eigenstates coalesce, resulting in the eigenspace ...

They recreate how a camera would see objects traveling at 99.9% of the speed of light, revealing surprising relativistic ...

A new ultra-flat lens challenges the limits of modern optics, capturing sharp color images once thought impossible. This breakthrough hints at a future where cameras are lighter, smaller, and smarter ...

Credit: Liz Sabol/Princeton University. For more than two hundred years, cameras have steadily evolved from bulky contraptions into essential tools of daily life. Today, they are everywhere—built into ...

People who develop presbyopia know the daily juggle between reading and distance vision. The eyes change with age, and close work stops being crisp without help. Bifocals have been the go to fix for ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even changed in color using structures so small they’re invisible to the eye.

Lenses are the most widely used optical devices. Camera lens or objectives, for example, produce a sharp photo or video by directing light at a focal point. The speed of evolution made in the field of ...

Chinese manufacturer, Viltrox, has announced the release of a new, pancake-thin AF 28/4.5 XF lens for Fujifilm’s X-mount cameras. The new Viltrox AF 28/4.5 XF lens is just 15.3 mm thick and weighs 60 ...

(Nanowerk News) Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. A team with researchers at the University of Tokyo and ...
