A multi-component objective which is the heart of a graphic arts image recording, printing or engraving system. The balancing of wide angular field, flat image plane and linear relationship between input scan angle and image height make scan lenses ideal for writing characters on film, laser engraving figures or recording characters and figures from texts. Scan lenses are sometimes also called F-Theta lenses because their image height is proportional to the scan angle (theta) and not the tangent of the angle.
