(Phys.org)—Researchers have designed an optical lens that exhibits two properties that so far have not been demonstrated together: self-focusing and an optical effect called the Talbot effect that ...

Chemical processes can be monitored using various optical fiber-based probes in normal-incidence reflection or surface-reflection configurations 1,2. A major advantage of such probes is their ...

Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now Penn State engineers have developed a new theory ...

A simple optical lens plays an important role for exploring the microscopic world in science and technology by refracting light with tailored spatially varying refractive indices. Recent advancements ...

(Nanowerk Spotlight) Optical lenses play a crucial role in a vast array of applications, from microscopy and astronomy to photography, medical devices, and machine vision systems. Traditionally, the ...
