ABSTRACT:
An optical system having a single, monolithic scan element as shown in the drawing in which surface 6 is concave, surface 7 is convex, surface 8 is convex, surface 9 is convex and the circumference of surface 9 is convex, surface 10 is convex, surface 11 is convex, and surface 13 is flat. f-theta correction is made primarily at surfaces 6, 9, 10 and 13. The element is molded from optical grade plastic and provides improved performance, no assembly adjustment, performance enhancement from its complex surfaces, and low cost.
