In this way, and almost by chance, researchers at TU Wien developed a novel microscopy technique that allows the refractive index of biological samples to be measured at a resolution far below what ...

Accurate determination of refractive index is fundamental to optical metrology, underpinning applications from precision length measurement to material characterisation and environmental sensing.

Ellipsometry is a non-destructive, optical measurement technique that characterizes the optical properties of thin films. It is highly sensitive to changes in the thickness and refractive index of the ...

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 ...
