Abstract
This paper discusses the optical design of motor vehicle head lamps using the new federal visual optical aim requirements. Methodology for using filament images from a head lamp reflector to create the required sharp gradient for visual aimable lamps is presented. The paper discusses hardware tolerance factors which would degrade a sharp cut-off, and methods are reviewed for accounting for and designing robustness against the tolerance factors. Hardware results are shown for designs using the techniques described in the paper.
