Process Control with Sub-Aperture Polishing

Scott Bambrick, Mike Bechtold, Dave Mohring and Adam Farnung

These tips and tools will help you use sub-aperture polishing systems effectively for a wider variety of materials.



As demand increases for aspherical optical elements, many optical fabrication shops are acquiring computer numerically controlled (CNC) sub-aperture polishing machines, which can produce a wide array of high-quality optics. Some of these optics would be impossible to manufacture using traditional techniques and materials, and they require different techniques to control the processes that achieve these results.
