Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. Researchers have fabricated and tested flat lenses called Fresnel zone ...

Draw a ray from the object to the lens that is parallel to the principal axis. Once through the lens, the ray should pass through the principal focus. Draw a ray which passes from the object ...

Flat lenses, such as metalenses ... said Associate Professor Kuniaki Konishi from the Institute for Photon Science and Technology. “This is due to a special type of photoresist or mask called ...

Science News and our parent organization, the Society for Science, need your help to strengthen environmental literacy and ensure that our response to climate change is informed by science.

A team of researchers from Universidad Carlos III de Madrid (UC3M) has developed an innovative technique that allows the ...

These lenses aren't exactly ready to wear, but they work. Credit: Xia et al, Cell Reports Physical Science/DOI 10.1016/j.xcrp.2024.102158 The lenses themselves consist of cholesteric liquid ...

One example is the question of which lens is right for a given task? There are common lenses like wide-angle, macro, and zoom, as well as lesser-known specialty ones like the anamorphic lens.

Researchers have examined whether axial eye growth increases after ceasing to wear soft multifocal contact lenses for myopia ...
