By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

Toyohashi University of Technology researchers in collaboration with Massachusetts Institute of Technology (MIT), have developed a new material capable of retaining high transmissivity after thermal ...

(Nanowerk Spotlight) Manipulating light is crucial for modern technologies, from the optical fibers transmitting internet data to the lasers in our smartphones. Despite significant advancements, our ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Materials that have a negative refractive index at optical wavelengths have now been fabricated by scientists in Europe and the US for the first time. Rob van den Berg explains why they could ...

Master Bond UV15-7LRI produces durable, tough and chemically resistant bonds, seals or coatings with excellent optical and electrical insulation properties. It has a low 1.481 refractive index and a ...
