How do they work?

More details: I know how single Amici prism works - it splits the light according to wavelengths, in such a way that one selected wavelength goes straight. No problem here.

Compensating prisms - as far as I can tell - are two Amici prisms in row, second one rotated 180 deg around the light path and adjustable by rotation around axis perpendicular to the light. I know they are used in Abbe refractometer to remove dispersion - moving adjustable one allows compensation of dispersion of the light in the sample and the measuring prism (one that is in contact with sample). But somehow I fail to imagine what is happening - is it just a fancy way of splitting and then recomposing light? And by adjusting the angle we change "recomposing power" of the configuration?
