Un dispositif escamotable (20), de type pare-soleil, est monté sur un instrument optique (10), tel qu'un télescope spatial. Le dispositif comprend des tiges (22, 24) articulées autour de l'instrument optique (10), dans des plans contenant son axe (12), ainsi qu' une enveloppe (26) souple et opaque, portée par ces tiges (22, 24). Des organes moteurs tels que des ressorts de torsion intégrés dans les articulations (28, 30) des tiges permettent de faire passer le dispositif (20) d'une configuration escamotée, dans une configuration active.
