ABSTRACT:
A lens mount for positioning a cylindrical lens in x, y, z and .theta..sub.x, .theta..sub.y, .theta..sub.z directional degrees of freedom includes a carrier with a lens-receiving cavity and a spring acting in the cavity adjacent one corner of the lens to apply a biasing torque in the .theta..sub.z direction directly on the lens. The lens is positioned with a planar x-y surface against a corresponding planar x-y surface of the cavity. A plate-like retainer wraps around an opposite curved surface of the lens to hold it in the cavity. Lens adjustments in the magnification x or y axis and .theta..sub.z directions are made against the applied bias by locating screws which pass through the carrier and contact the lens. The .theta..sub.z bias loads opposite lens edges against the .theta..sub.z locating screw and a guide pin, during translational adjustment.
