Abstract

A high-quality, compact, low-priced, and completely plastic scanning lens system for laser beam printers (LBPs) is now being readied for mass production. The key to its development was the use of aspherical and anamorphic scanning lens surfaces, including a newly developed "modified cylindrical surface". These surfaces made wide field angle and temperature change compensation possible through the effective control of field curvature, fe linearity, mirror tilting, back focus length, focal point change, and scanning width change. This paper describes the function and development of the system.
