Modern Optical Testing

This one-day course, taught by Dr. James Wyant, introduces the field of interferometric optical testing. Topics covered include basic interferometers for optical testing, concepts of direct phase measurement interferometry, testing of flats, spheres, windows, and corner cubes, long wavelength interferometry, testing of aspheric surfaces, measurement of surface microstructure, and absolute measurements offlats, spheres, and surface roughness.
