Abstract
A multiaxis rotation device for rotating a curved element about two, orthogonal axes is provided. The device includes two pairs of motors and two pairs of axis defining units, where each pair of axis defining units are placed on opposite ends of a line along one of the two orthogonal axes. The axis defining units each include a support for the curved element and apparatus for pressing the support against and pulling the support away from the curved element. The pulling away occurs when the motors corresponding to the axis defining unit are not providing rotation about the axis defined by the axis defining unit.
