Measuring Roughness. Surface roughness represents a crucial factor in optical communications. Excessive beam scattering results in: Signal loss and diminished data transfer rates. Crosstalk between ...

The Nanovea ST400 is used to measure the surface profile of an O-ring. Several surface parameters are automatically calculated from the O-ring profile including the most common, Sa (average surface ...
