The invention relates to an actuating device (15) comprising at least two coaxial bimetal disks (17, 18) and at least one axial strut (19) arranged between the disks (17, 18), the bimetal disks being mounted opposite each other and being deformable in opposite directions according to the thermal variations. The invention can be especially applied to the thermal compensation of an optical system.
Dispositif (15) d' actionnement thermique comprenant : - au moins deux rondelles bilames (17, 18) coaxiales, et - au moins une entretoise axiale (19) interposée entre les rondelles (17, 18), les rondelles bilames étant montées en opposition l'une par rapport à l'autre, et aptes à se déformer dans des sens opposés en fonction des variations thermiques. Application notamment à la compensation thermique d'un un système optique.
