Abstract
A shielding device (20) for optical and/or electronic apparatuses (16) is described, wherein said apparatuses may cooperate with incident electromagnetic radiation (X1, X2), in particular for space telescopes, the shielding device including: at least a filter (24, 26) provided for interacting with said incident electromagnetic radiation (X1, X2), for selectively filtering said radiation; and a support structure (22) for the filter. The support structure (22) is an inflatable structure, 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 the longitudinal extension axis (ZZ), and is essentially completely unfolded. Furthermore, the filter (24, 26) includes a filter body, which is provided in order to be transversely positioned with respect to said longitudinal extension axis, when the support structure reaches its active operating configuration.
