Abstract

The Large Optical Generator (LOG) recently completed the generating of six off-axis aspheres. It was decided to use the non-traditional technique of three-axis contouring to solve many of the fabrication and mounting problems. The process and the solutions it provides are discussed, as well as the resultant figure errors and how these compare to the traditional two-axis generating that LOG has done in the past.
