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 ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) say they have made it easier to manipulate light at the nanoscale. They have developed the first on-chip ...

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 Optilab ® differential refractive index (dRI) detector may be used in conjunction with any HPLC, FPLC, GPC or FFF separation system, plus a Wyatt DAWN ® or miniDAWN ® multi-angle light scattering ...

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 ...
