  • Controlled focus mirror with rim controlled flexure
    Patent number: 4059346
    Abstract: A variable focus mirror comprising a uniform elastic disk having a mirror finish on one face thereof, which is urged against an annular fulcrum concentric with the disk by a uniform force applied at the rim of the disk. This force causes the flat disk to be flexed into a substantially spherical, nearly parabolic shape. The magnitude of the force applied controls the degree of flexure and hence the focal length of the spherical mirror. For laser beam focusing the materials are selected to be able to withstand the laser energy being reflected.
