Abstract
In a continuous path enlarger having an illumination system for illuminating a very wide continuously moving original and projecting the image thereof onto a much wider sheet of light sensitive recording material moving synchronously with the original, the improvement wherein the illumination system includes a plurality of identical abutting, illumination sources each having a light source and a lens system with the final lens thereof being in the shape of a parallelogram having straight side edges in contact with the adjacent side edges of each adjacent final lens, and with the side edges being at an acute angle to the direction of travel of the recording sheet. Further, the plurality of image areas on the recording sheet preferably overlap each other. Thus, the total amount of light received at any point on the recording sheet passing through an angled edge of one of the plurality of image areas integrates across the width of the exposure area and is sufficient to effect proper exposure of the recording material so that uniformity is achieved over the field of exposure.
