Abstract
An improvement is provided in a cathode ray tube screen exposure device to achieve optimum optical alignment of related components constituting the exposure optical system. In relationship with a discretely positioned light output area, separate means are provided to achieve fine adjustable positionings of both the source of radiant energy and the associated reflective means in both x and y related directions in planes normal to the optical axis, and in the z related direction in planes parallel to a central axis. Each of the respective optical alignment adjustments is individually effected by linkages to separate exteriorly located control means. Retentive means are incorporated in the respective linkages to insure accurate maintenance of the cooperative adjustments.
