Machining nonconventional-shaped optics. [Axicons, waxicons, torics, and multifacet]
Nonconventional-shaped optics are being machined for use in laser optical systems. The fabrication processes incorporate special-quality diamond tools and specially constructed turning machines. The shapes produced include axicons (conical-shaped mirrors), waxicons (a compound axicon with a ''W'' cross section), torics, and multifacet mirrors. Whereas conventional-shaped optics are very impractical to lap. The axicons and waxicons produced were estimated to have surface straightness as good as 5 ..mu..in. (125 nm), over 3 in. (76 mm) of length, and angular accuracy as good as 2 arc seconds. A toric mirror was estimated to deviate (peak to valley) from a best-fit radius by 4 ..mu..in. (100 nm) over 2.25 in. (57 mm) of surface length.
