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.

Abstract: A protective device for optical and/or electronic apparatuses, in particular space telescopes, is described, wherein the device is such as to removably close an aperture, through which apparatuses may be accessed, the device being such as to achieve a first and second operating configuration, respectively, for allowing or inhibiting access to apparatuses through aperture. The device includes a supporting structure having at least one supporting beam, which is transversely positioned with respect to aperture; a plurality of covering elements comprising at least a pair of elements, which are rotatably coupled to the same supporting beam; and actuation means for rotating the covering elements between a first and second angular position, in order for the device to attain the first or second operating configuration, respectively, wherein, in the second operating configuration, the covering elements are such as to define together a screen for aperture.
