Optical Polishing is a fabrication technique developed specifically to achieve minimal defects and smooth micro-roughness values. The study of surface texture is becoming more and more common place for quality control. Because of this need to maintain quality and to minimalize, surface defects and imperfections there are more and more technologies available for looking at the surface and due to the differences in these techniques; each has its own specialist applications. Here the benefits of both coherence scanning interferometry systems are used to measure surface metrology with nano and micro metre precision for both form and texture.
