Abstract

Using Fresnel lenses in scanning systems can have several benefits for the manufacturing process and certain performance advantages. Among the advantages are that the thinner Fresnel lenses are more economical to injection mold while reducing dispersion in the material. Designing and fabricating Fresnel lenses for these systems does, however, present some unique challenges. First, the issue of designing these systems is addressed by evaluating possible geometries and simple designs. Second, some design concepts are evaluated. Manufacturability is the next challenge due to the unique requirements for these scanning systems and finally, the fabricated surfaces must be evaluated. Concepts and strategies for addressing all these issues are explored.
