This paper presents the recent developments of bimorph structures usable for X-ray mirrors, monochromator crystals, and gratings. The adaptation of the structure to the 3 applications mentioned above is done by choosing the upper plate material and surface coating. The bimorph structure is designed to produce a simple spherical bending of the active plate, or more sophisticated shapes as ellipsoids or parabola. The bimorph structure can be mounted in a mechanical housing able to properly support it. High voltage amplifiers with digital input fitted to control the shape as well as a curvature measurements system may be delivered providing the possibility of closed loop operation. Standard versions of bimorph mirrors and gratings are available. Most of the development work was done under ESRF support.
