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 ...

Thulium fiber lasers, operating at a wavelength of 2 micrometers, are valued for applications in medicine, materials ...

Researchers at Harvard’s John A. Paulson School of Engineering and Applied Sciences have announced the first on-chip metamaterial with a refractive index of zero — meaning the phase of light can ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...

Biotech Fluidics announces REFRACTiMASTER® - a new HPLC refractive index (RI) detector suitable for detecting compounds with little or no UV activity including simple sugars, complex carbohydrates, ...
