Measurement of ceramic polished surface

Non-contact roughness measurement　Ceramic

Ceramic polished surface(450x350μm)
White light interference measurement results(150x150μm)


It is a comparison of the measurement results of the ceramic polished surface with non-contact type (Crispy),
contact type, laser AF, and white interferometry type.



Crispy has a larger amplitude of fine irregularities, but the roughness curves match well.
