Abstract
An imaging apparatus for a laser thermal printer (1) provides 100% fill at a media plane (60). The imaging apparatus (10) comprises a laser array (12), and focuses it on a modulator lenslet array (30). The illumination optics (13) combines light from each diode laser (14) in modulator lenslet array (30) and focuses light onto modulator sites (42) on the modulator array (40), with less than 100% fill. A printing lens (50) focuses an image of the modulator lenslet array onto a media plane (60) at essentially 100% fill.
