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 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 ...

The measured ellipsometric parameters (Ψ and Δ) include the physical properties of the layer structure being analyzed. This information shows the layer thickness and refractive index concerning the ...

A new composition of germanosilicate glass created by adding zinc oxide has properties good for lens applications, according to researchers. This marks the discovery of a novel glass family. A new ...

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 ...
