Paper Abstract

Advances in diamond turning technology have offered optical designers new degrees of freedom in beam shaping optics. While designers have these new manufacturing methods at their disposal, they may not be aware of special process limitations and cost drivers. The purpose of this paper is to present some of these critical manufacturing issues. We will discuss briefly special beam shaping optic types and applications. Then in more detail we will discuss the four key diamond turning techniques and the types of optics they can produce. These four key manufacturing techniques are: standard 2 axis diamond turning, slow tool servo, fast tool servo, micromilling. During the discussion we will present surface shapes, process limitations, as well as cost drivers for each technique. In summary will we present this data in a matrix that will aid the designer in selecting manufacturing techniques and optic types.
