Abstract: An optical alignment device comprised of two "H" shaped structures may be used to precisely position an optical element in two orthogonal directions. Each "H" shaped web structure includes two flanges extending from opposite ends of a center web having a centroidal flexure axis. The "H" shaped structures also each include an aperture extending through the flanges and the web. The center webs may be resiliently flexed, allowing the angle between the flanges of each "H" shaped structure to be adjusted by rotating screws fitted through one flange and threaded to the other. The "H" shaped structures are mounted together so that their flexure axes are orthogonally oriented with respect to each other and so that the apertures of each structure are aligned to form an optical path cavity.
