|Issue Date:||2018||Volume:||Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave||Editors:||Lystrup, Makenzie; MacEwen, Howard A.; Fazio, Giovanni G.; Batalha, Natalie; Siegler, Nicholas; Tong, Edward C.||Series:||PROCEEDINGS OF SPIE||Number:||10698||First Page:||106984V||Abstract:||JANUS is the camera of the ESA mission JUICE, dedicated to high-resolution imaging in the extended-visible wavelength region (340 - 1080nm). 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.||Conference Name:||Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave||Conference Place:||Austin, Texas, United States||Conference Date:||10-15 June, 2018||URI:||http://hdl.handle.net/20.500.12386/28182||URL:||https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10698/106984V/Modeling-the-JANUS-stray-light-behavior/10.1117/12.2313204.full?SSO=1||ISSN:||0277-786X||ISBN:||9781510619494
