Paper Abstract

In the scanning optical system for laser beam printer, so-called f-0 lens is utilized to provide a scanning spot of constant velocity from deflected light beam having constant angular velocity. Then, f-8 lens is designed to have proper amount of residual distortion. One important point at the optical design of such kind of optical system is to find out the relationship between distortion and point spread function of the lens. In this report, the relationship is made clear by using aberration theory. With some designed examples it is shown that f-8 lens is suitable for scanning purpose, and that the lens makes us highly effective use of laser beam energy by reducing the deformation of point spread function with respect to the deflection angle of beam. As the example of application, the optical elements for semi-conductor laser scanning system are presented.
