Abstract

A simple method is described which permits the rapid fabrication of nickel plated aspheric metal mirrors for infrared optical systems. The method employs precision machining of the substrate and the plated mirror with a calculated series of tangent radii designed to closely approximate the desired aspheric curve. The process described has several advantages; it removes irregularities from the substrate and the plating, it provides an even plating layer, it produces a smooth machined surface close to the desired shape and ready for polishing and figuring, and it can be done on most precision machine lathes. Since most of the asphericity is machined into the surface at the start, a considerable reduction in fabrication time can be realized over conventional methods.
