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 cylindrical carrier movable to a selected z axis position within a V-shaped channel track of a base including an elongated rail. The carrier has a radially extending bracket whose position relative to the rail is adjusted to rotate the carrier within the track channel to set the .theta..sub.z rotational direction position of a lens positioned with a planar x-y surface against a corresponding planar x-y end surface of the carrier. A fixture removably attached between the carrier and the retainer provides a push-pull mechanism which applies a biasing torque on the lens, to load opposite corners of the lens against guide pins of the carrier. A movable member on the detachable fixture adjusts the position of the retainer and lens translationally in the x or y magnification direction against the bias of the applied torque, independent of the .theta..sub.z rotational adjustment.
