Abstract

The new formula that was used to develop the free-form-surface is more advantageous in regard to spot size and linearity than usual aspherical and troidal lens systems. However, the free form surface is much more complicated, compared to the usual optical system. Now, we would like to express the advantage of the free-form-surface design. We had to improve the nano CADCAM and compensation systems for the fabrication of injection molded plastic optics. In the future we plant to design a new optical system, now that the development of the one-piece f-theta lens has been completed. We describe the free-form optics now.
