An alignment fixture for an optical instrument such as an optical correlator providing for the adjustment of the alignment of an element thereof, such as a matched filter or multiple matched filter or a multiple holographic lens, along at least two transverse x and y axes, and also rotationally .theta. in roll about a z axis perpendicular to the transverse x and y axes. The alignment fixture is constructed with a base plate which is designed to be mounted on a stabilized optical bench. The base plate is movable along the z axis for adjustment therealong, and includes a vertically extending frame member. An L-shaped lift angle plate is vertically movably and supported by the vertically extending frame member to provide for alignment adjustments along the y axis. The L-shaped lift angle plate movably mounts a rotational stage in a manner which provides for alignment adjustments along the horizontal x axis. The element being aligned, such as a matched filter, is mounted on the rotational stage with an angular adjustment being provided for .theta. roll angular adjustments. Each adjustment is provided by a micrometer drive, preferably a pulse driven motor micrometer controlled by a computer.
