ABSTRACT:
A beamsplitter/staggerer (24) for multi-beam laser printers is disclosed. The multi-beam laser printer is comprised of the beamsplitter/staggerer (24), a spatial light modulator (16) having at least two rows of staggered modulator pixel elements (19), and an illumination system comprised of a laser array (10) and an optical system (13) which provides a narrow line of laser light. The beamsplitter/staggerer is adapted to split the narrow line of laser light into at least two parallel lines of light, and to split each of the parallel lines of light into regions, such that substantially all of the light from the illumination system falls onto each of the modulator pixel elements (19) in each of the rows. In one embodiment, the beamsplitter/staggerer comprises a pattern of reflecting areas (26) and transmitting areas (27) wherein a shape of the regions defined by the beamsplitter/staggerer matches a shape of the modulator pixel elements (19).
