Abstract: The invention concerns a device for fixing and adjusting a member to be supported, characterised by the fact that it comprises: a support base (1); two triangular levers (6), each of the said levers comprising two arms (7, 8) disposed in a triangle and connected together at one of the vertices (9) of the triangle, each of the said levers being articulated on the said base at its respective vertex, a first one (7) of the two arms of each lever being extendable and connected at its free end to means of fixing (14) to the said member; and an adjustment means (5) mounted on the said base and arranged to make the second arm (8) of each lever pivot in the plane of the said lever. Application to the fixing and adjustment of a precision optical element.
