A multilayer piezoelectric deformable bimorph mirror is presented for use in astronomical telescopes, laser industrial systems, guidance and tracking systems, comprising a housing 1 made as a sleeve with a cover 2. The reflectance surface 3 is formed on the outer side of the bottom of the sleeve. At least two piezoceramic plates 4 are coupled to the inner surface of the sleeve bottom not extending beyond the limits of the reflectance surface. The piezoceramic plates have solid electrodes 5 on their opposite surfaces, polarisation vectors 6 of adjacent piezoceramic plates are oppositely directed and their like electrodes are electrically connected between each other by means of wires 7. The sleeve is designed in one piece with the bottom of a variable thickness and the central part of the bottom carrying the reflectance surface 3 has a greater thickness compared to the peripheral part. The cavity of the housing 1 may be filled with an elastic sealant 10. <IMAGE> |
