Multi-zone measurement

Angle dependent ellipsometry reflection scans

Kinetic runs

Ellipsometry is an excellent tool to follow adsorption processes in situ.
The mass coverage and thickness of the adsorption layer is monitored and the adsorption isotherm as well as the underlying kinetics are studied. Optrel can supply a cells for solid/liquid interfaces or liquid-liquid interfaces.

Additonal channels

In many kinetic runs you would like to record additional experimental parameters such as temperature, surface tension, huminity, pH value. This can be achieved in a variety of different ways with the Multiskop software. A elegant solution is the use of the free channels of the ADDA converter. The external parameter are recorded, stored and displayed. So you can generate runs time, Delta, Psi, temperature, pH-value. The menu allows you also to select an external parameter as a x-axis. For instance you can display the measurment y-axis: Delta, Psi, x-axis: temperature.
trinsic errors due to slight misalignments of the sample or imperfections of the sample. Nullellipsometry means select a setting of the optical components that cancel the light at the detector. The corresponding Nullsetting of the optical components provides the ellipsometric angles Delta and Psi.
