Ocular diseases can cause vision problems or even blindness if they are not detected early. Some ocular diseases generate irregular physical changes in the eye; therefore, reliable diagnostic ...

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 ...

Using 3D printing and porous silicon, researchers at the University of Illinois Urbana-Champaign have developed compact, visible wavelength achromats that are essential for miniaturized and ...

(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 ...

Johnson & Johnson is pushing boundaries in optical and material science with the launch of the first daily disposable contact lens for people with both astigmatism and presbyopia. The New Brunswick, ...

Using a single lens that is about one-thousandth of an inch thick, researchers have created a camera that does not require focusing. The new lens could drastically reduce the weight, complexity and ...
