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 ...

In its current form, the new diffuser could be used to calibrate a wide range of imaging systems, but the researchers believe that their mechanism could ultimately lead to holographic video screens or ...

A refractometer is a device used to measure the refractive index (n) of a substance. In this article, we discuss what a refractometer is and how it works, the different types available and their ...

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 drop is a small volume of liquid, bounded completely or almost completely by free surfaces. Due to the different refractive indexes of water and air, refraction and reflection occur on the surfaces ...

insights from industryErik GublerProduct ManagerMettler-Toledo GmbH In this interview, AZoM speaks to Erik Gubler, Product Manager at Mettler-Toledo GmbH, about e-liquid testing; how to do it, why it ...

New data from the National Institute of Standards and Technology (NIST) will assist in the design of optics for liquid immersion lithography, an old idea that recently has attracted new interest as a ...

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 ...
