Tutorial 1 - Features of reflectivity curves

The edge of total internal reflection

The edge of total internal reflection, . The position, i.e. the angle at which total reflection is found depends solely on the difference of the dielectric constants of the two infinite media – the prism and the covering medium, typically air or water. These values are known and, hence, is fixed for a given system.

For this reason, this angle is an important value to validate correct sample alignment. Note, we sometimes try to measure very minute changes of the minimum position of the plasmon. It is important to crosscheck these small differences with neutral feature like . We recommend to always include this region in any SPR experiment.
