Southampton optical circuit start-up Stratophase has developed a sensor that can measure the refractive index of liquids to better than one part in a million (1ppm). After the team got their prototype ...

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 ...

The applications of spectroscopic ellipsometry for the precise characterization of liquid-liquid and liquid-air interfaces include surface science, biomedical applications, thin film coatings, and ...

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 ...

Light bends when travelling through a concentration gradient of sugar in water. The top layer of liquid is pure water while the bottom layer is concentrated sugar water. In these layers, there is no ...

On-chip refractive-index monitors suit industrial process control and biodetection, as the UK company seeks commercialization partners. Winning venture capital (VC) funding is a major milestone for ...

The Refractive Index Matching (RIM) test rig at the University of Bristol is a specialised closed-circuit flow facility designed for high-resolution measurements within and around complex geometries.

When a ray of light is incident at normal incidence, (at right angles), to the surface between two optical materials, the ray travels in a straight line. When the ray is incident at any other angle, ...
