The Fisher Scientific™ Abbe Bench-top Refractometer measures refractive indices of liquid and solid samples at D-line (589nm), featuring a combination of the Brix and refractive index (nD) ...

The refractive index of a material defines the angle through which light is bent when it travels between a material and the vacuum. Ordinary materials such as glass have refractive indices between one ...

The Rudolph Research J257 Wide Range Refractometer was developed by working together with laboratory refractometer users from the polymer, petroleum, petrochemical, pharmaceutical and essential oil ...

Few people today would dispute that the use of Mie Theory provides the only route to accurate particle size analysis when measuring fine particles using laser diffraction. The international standard ...

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 ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...
