WebThus, full surface texture symbol will inform us of: a is a type of roughness measurement – possible conventional signs are Rq (Root mean square (RMS) height variance) and PSD (Power spectral density (PSD) of surface height). b is the value of Rq or PSD – unit of measurement is micrometer (µm). WebRoughness describes high spatial frequency errors, meaning very small deviations on the order of Angstroms (10 -10 m). Understanding the surface roughness of optical surfaces is critical to control light scatter, as scatter can be proportional to the surface roughness of the optics. Light scattering and absorption from surface roughness have a ...
