Abstract
In laser scanning and recording systems, the results obtained with a given lens will be highly dependent upon the width of the incoming beam. Wide variations in resolution, total power and power distribution within the focussed spot result from varying the input beam width. Previous work by researchers in the field identify these interrelationships for specific conditions and applications. This paper provides characteristic curves showing these interrelationships in sufficient detail to provide the system designer with simple design aids. This allows selection of the most suitable parameters for the system under consideration. Further illustrations, and the associated discussions, help to provide a mental picture of the changes that occur about the focussed image plane. Mathematical relationships and references are provided, but are not essential to develop an understanding of the resulting characteristics.
