Tutorial 2 - Simulate SPR curves with WinSpall
A simple start: a laser beam, a prism and air
Let us consider the simplest experiment: A laser beam is reflected from the base of a prism and the reflected light is collected as a function of the angle of incidence (taken against the surface normal). We need the optical constants of the prism and of air.
This is what we need to fill into our table of optical components: No. 1 is the prism. Not a layer and so we chose “0” for the thickness. The real part of the dielectric constant is e' = 2.29 in our example (corresponding to a refractive index of n=1.51). There is no adsorption in the glass and, hence, the imaginary part is zero. The next component (No. 2) is air with “no thickness”, and e'=1 (n=1), and e''=0 (no absorption). We are done. Let's click “Ok”.
