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 ...

There has been interest in the Negative Refraction Index (NRI) material at optical frequencies. There are two approaches to optical frequencies. 1)Volumetric structure: it is based on the spherical ...

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 ...

The original goal was to investigate biological samples on a molecular scale – but this soon led to stubborn technical problems. Eventually, however, the researchers realized that the very source of ...

NASHVILLE, Tenn. — Wave-guided optics application technology may now help patients with keratoconus, according to a speaker at Optometry’s Meeting. “We know a lot of our irregular cornea patients ...
