Layout and Features of Optical System Aberration Design for Highly Productive Laser Printer with Minimum of Components

In the context of laser optics (theory of quasi-gaussian beams) the feasibility study is performed to minimize the configuration and reduce the cost of main components of optical system for 1200 dpi A3 and A4 laser printers of high production. It is shown that even the highly productive 1200 dpi A4 laser printer may have only three-lens optical system: two-lens illumination part (laser beam astigmatic collimator) and one-lens projecting and focusing part (F-Θ-lens).
