Abstract
An arrangement for the recording of rastered half tone pictures, in which each covering dot is formed in a raster field, with the size of the dot being dependent upon the light directed on different portions of the raster field, by a plurality of individual light beams coordinated in a line and focused on the recording medium by objective lens means, in which an optical element is disposed in the beam path to such objective lens means to refract light in the direction of said line, with such optical element occupying approximately half of the total projection cross section of all of the component light beams, and with the boundary of the projection cross section extending transversely to said line direction of the light beams.
