The invention relates to a mosaic adaptive bimorph mirror that can be used for the static and dynamic guidance of the wave front radiation in a variety of optical devices and systems, including astronomic telescopes, industrial laser systems and optical guidance and tracking systems. The subject-matter of the invention is a mosaic adaptive bimorph mirror which ensures the enhancing of the amplitude of the adjustable displacements of the optical surface and increasing the sensitivity. This is obtained by the fact that the mirror uses multilayered bimorph structures in order to distort the reflecting surface. The bimorph strucres are carried out in the shape of some piezoelectric elements, containing at least two piezoceramic plates (3), coupled at the basis of a sleeve-shaped housing (1). The inner cavity of the housing is filled with a resilient sealing element (9). In addition, the constructive solution allows to reduce the effort for making, assembling and polishing, and improves the quality and stability of the initial shape of the optical surface as well as the increase of the mirror power and safety.
