This corrector allows to deform the mirror surface at nanometre level but for this purpose it requires resolutions better than 0.02, by using ultra-low constant springs, and to preserve the introduced deformation it is needed to be stable at the same level. The corrector needs to be insensitive when dismantling and remounting the mirror. In the other hand in order to support the corrector its structure is attached to the bender frame and the spring force is transmitted through a level arm by means a bearing articulation. This introduces a small friction but it is still preferably to eliminate it. A new method based -k spring-like constant principle is proposed. Based on this technique it is possible to stabilize the force exerted on the mirror below 0,02N for an error range more than 1 mm. In addition applying the principle to a flexure it allows to compensate it in an angular range in within the torque variation tend to be null, below 0,005 Nm, thus becoming a short range, frictionless and zero torque articulation.
