Recent Developments in the UltraForm Finishing and UltraSurf Measuring of Axisymmetric IR Domes
Abstract
OptiPro demonstrated the polishing and measurement of a glass tangent ogive using their previously developed belt polishing equipment and their latest UltraSurf measuring equipment. The surface roughness of the new splice-less belts showed a 8 to 9 Angstrom surface roughness. New tool path options were also demonstrated that compensate for radial and angle errors during polishing. Test ellipsoids were polished with the new tool path correction that improved surface accuracy from 5.23 micrometers peak to valley to 1.38 micrometers. The UltraSurf non-contact metrology system was used to measure the surface accuracy of a small convex dome and the surface accuracy and thickness of the as-ground ogive.
