Surface Plasmon ResonanceFeatures of a SPR reflectivity curveWhat influences the features of a surface plasmon resonance curve?This little tutorial helps you understand the most important features of a SPR curve. We determine the features of such a curve and discuss all parameters that influence the “looks” of this curve. This will help you understand the data you measure. By the way: The above plots were generated using WinSpall. Learn more about this SPR simulation software in our WinSpall tutorial (see www.res-tec.de).

The edge of total internal reflection. We will learn that this feature is not just there for some strange physical reasons: it is also an important feature to validate our measurement.2. The resonance angle (or “the plasmon” itself). The actual angular position but also the depth will be important to learn something from “the plasmon”.3. The full width at half maximum. Optical constants do matter. We will see how.
