This article explains the benefits of the non-contact inspection method used by 3D optical profilers, and outlines the best practices and measurement results for some specialized PTB ...
Stylus-based surface profiling is a standard technique for accurate, repeatable surface shape, topography and step height measurement in applications ranging from semiconductor R&D to solar cell QC.
The performance, reliability and longevity of machined parts often depend on the physical characteristics of their functional surfaces. However, legacy surface roughness parameters, such as R a, are ...
