Title: Surface finish measurements of diamond-turned electroless-nickel-plated mirrors

Conference ·
OSTI ID:5274693

Surface roughness data are presented for a matrix of diamond-turned electroless-nickel samples having a combination of six phosphorous contents and four heat treatments. Roughness measurements were conducted with commercial optical and stylus profilometers (Wyko and Talystep). The results are discussed in terms of the material composition and heat treatment, plus other factors having an observed influence on the surface roughness. For the optimum material properties, full-length (665 ..mu..m) restored 20X Wyko scans yielded values of better than 10A rms.
