Measuring Rough Surfaces


I can get good meausurements from a machined Surface, but e.g. when I try to scan a coin, only features with a depth of 16 um are measured (with 10X objective). I see there are nice examples of a Euro cent. I wonder what type of settings one should use to get such mesaurements.


Hi Mahdi,

Thanks for your post.

The scan that you see on the ProfilmOnline homepage was stitched together using a 10x objective with a digital zoom of 1x. The scan length was 280 µm with a backscan of 30 µm and used the envelope center analysis mode with an envelope threshold of 1,25%. This was done with the fast scan speed and covered an area of 23,5 x 23,5 mm.

I’ll get in contact with you via email in order to optimize your scan settings with the 10x objective.
