Most surface texture parameters are related to heights. But in some applications lateral features and their spacing are as (if not more) important.
Have you ever heard of the Sdr parameter? What if it turned out to be the ideal indicator for characterizing the functionality of your surface data?
Discover how to set up appropriate experimental conditions before imaging a sample to be used with the Mountains® SEM 3D reconstruction tool
Are you measuring surface roughness over an area? Ever wondered whether it is OK (or not) to compare values calculated (Sa, Sq, Sz etc.) with profile surface texture specifications (Ra, Rq, Rz etc.)? François Blateyron, Digital Surf's ISO surface metrology expert, sheds light on this issue which can easily cause confusion.
