Abstract
We exploited a ray-tracing Montecarlo code to investigate the effects of stray-light on the performances of the Wide Field Imager (FoV = 1.5 deg) on board the EDGE satellite. We found non negligible stray-light contamination up to ~ 8 deg off-axis angles. We discuss the benefits of a baffle in order to reduce this contamination, that would strongly affect the telescope sensitivity, and present two possible baffle designs based on results of simulations.
