Abstract
An enhanced mechanical design for laminar weak-link mechanisms with centimeter-level travel range and sub-nanometer positioning resolution is provided. A multiple parallelogram weak-link structure includes a predefined pattern of a plurality of perpendicularly arranged groups of connecting links, each link having at least one pair of weak-link connections. Each of the plurality of perpendicularly arranged groups includes a terminal for mounting to a fixed base. The multiple parallelogram weak-link structure includes a moving part for mounting on a carriage, providing precisely controlled movement with stability in one direction. A two-dimensional (2D) ultra-precision scanning stages assembly for x-ray nanoprobe applications includes multiple redundantly constrained weak-link structures, a vertical ultra-precision positioning stage, and a horizontal ultra-precision positioning stage.
