Abstract
In concentration systems using Fresnel lenses the effect of the chromatic aberration can become important. In this paper we propose a method to take this effect into account for designing purposes. Also we define a parameter that allows one to estimate the degradation of the thermodynamic quality of the concentrator due to this effect. This parameter follows a hyperbolic law, with the acceptance angle showing that it is important to consider chromatic aberration when modeling concentrators with a high concentration factor. However, this complexity is unnecessary for moderate or low concentration factors.Keywords
