Abstract:
1. Shielding device for optical and/or electronic apparatuses, which cooperates with incident electromagnetic radiation, the shielding device including: at least two filters for interacting with said incident electromagnetic radiation, for selectively filtering said radiation; and an inflatable support structure for the filter which is able to achieve an operating stand-by configuration, in which it is substantially folded together, and an active operating configuration, in which it extends along a longitudinal extension axis and is essentially completely unfolded; wherein each of the filters includes a filter body comprising a shielding portion and a pass-through portion, which is transversely positioned with respect to said longitudinal extension axis when the support structure reaches its active operating configuration; wherein at least the pass-through portions of the filters have transversal dimensions, with respect to the longitudinal extension axis, said transversal dimensions decreasing with a decrease in distance between filters and optical and/or electronic apparatuses, the shielding portions of the filters shielding the incident electromagnetic radiation having incident angles increasing with a decrease in transversal dimensions of the pass-through portions.
