ABSTRACT:
Methods for directing an optical beam and for making an apparatus for directing an optical beam are described. One such method may include applying a first force to a plate to move the plate from a first angular orientation to a second angular orientation wherein the plate contacts a stop in the second angular orientation. A reflective portion of the plate is stopped from rotating beyond the second angular orientation. A second force can be applied between the plate and the stop to hold the plate against the stop in a plane substantially parallel to a substantially planar surface of the stop. An apparatus for directing an optical beam may be made by coupling an array of plates to a base assembly wherein each plate is movable between a first angular orientation and a second angular orientation.
