<p>An X, Y positioning unit, mount or fixture is designed. The fixture (60) includes live hinges (74, 100) which join an optical element holder (72) to a fixed plate (70) and pivot the holder about orthogonal axes crossing at the center of an optical element holder such that small movements of the hinged holder about the hinges adjusts the position of the center of the optical element holder and thus the optical element. When the appropriate adjustment has been made, the holder is clamped in the adjusted position to the fixed plate through the use of the clamping plates (120, 122) to provide a rigid structure capable of withstanding high static and dynamic loading.</p> |
