Abstract
The aim of this article is to introduce a dedicated simulation package, named GETFOCOS, that combines Geant4 and ray-tracing algorithms that can be used on the characterization of the optics of a generic Imaging Atmospheric Cherenkov telescope as well as on the optimization of its focal plane geometry. The image spot size is evaluated for both cases in a large field-of-view observation scenario. This tool allows to perform fast but precise tests for different optical options. The specific case of a Fresnel lens, inspired by the concept developed for the GAW experiment, is analysed. However, this intends to be an universal and relevant tool for any kind of optical system. A complete characterization of the optics is presented together with a study for the optimization of the focal plane shape.
