Abstract
A linear positioning apparatus includes an intermediate portion having an axis, and first and second end portions mounted with flexure legs thereto. The flexure legs accommodate motion of the intermediate portion relative to the end portions along the axis, but inhibit motion of the intermediate portion relative to the end portions in directions not parallel to the axis. The apparatus can accommodate forces having off-axis components, and produce motion that comprises substantially no off-axis component. The apparatus is useful in, for example, optical systems where precise linear motion is required.
