<p>A beam of light (5) is directed through a negative (4) and two objective systems (6, 7) are disposed in the resulting light path to create two separate optical paths. One path from objective (6), forms a main image (2) on a light-sensitive paper (1) via two parallel mirrors (8, 9). A second path, from objective (7) passes via two right angled reflecting assemblies (10, 11) angled at 135 DEG (Angle A) to each other to form a secondary image (3) on the paper (1) with the image (3) turned through 90 DEG with respect to the image (2).</p> |
