Influence of surface skewness on the zero-order light scatter for a given roughness

The results ofthis study are: 1 . Inthe surface roughness range Rq < O.08A. the surfaces without Skewness obey the 115 formula within 5%. 2. Skewness in the surface height distribution reduces the light scatter for a given surface roughness. The latter result is useful for the manufacture of optical surfaces. For instance, for a given surface roughness, a diamond turned optic will perform better than an optic produced by grinding. Also a diamond turning machine can produce complicatedly shaped optical components. Keywords: light scattering. total integrated scatter, surface finish, skewness,
