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 ...

A MICHELSON two-beam interferometer can be used for refractive-index determination by measuring the shift of the achromatic fringe when a specimen of known thickness is placed in one arm of the ...

High frame rate and highly sensitive imaging of refractive index changes on a surface is very promising for studying the dynamics of dissolution, mixing and biological processes without the need for ...
