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 ...

Researchers at Lawrence Livermore National Laboratory (LLNL), Livermore, CA, have employed multi-material 3D printing to create tailored gradient refractive index glass optics that could make for ...

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 ...

Researchers reported a novel technology enhancing the high transparency of refractive polymer film via a one-step vapor deposition process. The sulfur-containing polymer (SCP) film produced by ...

Schott unveiled at SID Display Week a new-generation optical glass wafer designed with a field of view (FoV) wider than any AR/MR device currently on the market, thanks to a further increased ...

Manufacturers of Augmented and Mixed Reality (AR/MR) devices have a new solution to boost user experience by using the new generation of Schott's RealView high-index glass wafers with a refractive ...

A moth’s eye and lotus leaf were the inspirations for an antireflective water-repelling, or superhydrophobic, glass coating that holds significant potential for solar panels, lenses, detectors, ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...
