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.

A mounting fixture for an optical instrument, such as an optical correlator, providing for the precise mounting and positional adjustment therein of an element, such as a multiple holographic lens, at least along two transverse x and y axes, and also rotationally along. theta. in roll about the z axis,. gamma. in pitch about the x axis, and. beta. in yaw about the y axis. The mounting fixture enables the holographic lens plate in an optical correlator to be positionally adjusted and then fixed stably in the optical correlator.
