The camera will observe Jupiter and its satellites providing detailed maps of their surfaces and atmospheres. During the mission, the camera will face a huge variety of observing scenarios ranging from the imaging of the surfaces of the satellites under varying illumination conditions to limb observation of the atmospheres. The stray-light performance of JANUS has been studied through non-sequential ray-tracing simulations with the aim to characterize and optimize the design. The simulations include scattering effects produced by micro-roughness and particulate contamination of the optical surfaces, the diffusion from mechanical surfaces and ghost reflections from refractive elements. The results have been used to derive the expected stray-light performance of the instrument and to validate the instrument design.ELETTRONICOenConference paper10.1117/12.23132042-s2.0-85054833305000450864600126https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10698/106984V/Modeling-the-JANUS-stray-light-behavior/10.1117/12.2313204.full?SSO=12018SPIE10698E..4VGFIS/05 - ASTRONOMIA E ASTROFISICA
