Hello,
I´m trying to characterize topographies. In gwyddion I easily get the
Parameters for roughness and waviness, but I have some questions about it:
1. I read: to calculate the rougness and waviness data I need to filter
the AFM-Data first. So my question: In gwyddion when I use the roughness
parameters application, do I first have to filter the data, or does gwyddion
filter the data automatically in this application?
2. Does it make sense, to calculate the roughness in smaller areas of the
sample, and the waviness in a greater areas? Because of the different
structural size which matters. I thought about that, because I realized that
when I change the thickness of the Scan line the roughness value drops with
expanded lines, the waviness as well. So how should I use the application of
the roughness parameters to describe my topographies best?
3. I have a glass substrate covered. But the coating doesn´t cover the
glass everywhere. Has gwyddion any way to calculate the coverage factor?
Thanks Lena
