How can I characterize lateral features?

Most surface texture parameters are related to heights. But in some applications lateral features and their spacing are as (if not more) important.

What is the Sdr parameter and when can it be used?

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?

SEM image 3D reconstruction: what accuracy can I expect?

Discover how to set up appropriate experimental conditions before imaging a sample to be used with the Mountains® SEM 3D reconstruction tool

Does it make sense to compare Ra and Sa values?

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.

Using a four-quadrant detector: how to give your SEM images a 3D upgrade

A whole new world of 3D awaits users of scanning electron microscopy (SEM) coupled with Mountains® software. Christophe Mignot, Digital Surf CEO and specialist in SEM image analysis, runs through one of the coolest techniques available for bringing to life even the tiniest details contained in images.

7 tips for producing SEM stereo pairs

The Stereoscopic Reconstruction operator available in Mountains® enables users to obtain a precise 3D model from a stereoscopic pair of SEM images in just a few seconds. However, before running this operator, there are a few things you need to know.

The delicate art of applying filters to a surface in order to prepare it for analysis

Do I need to use an S-Filter on a surface the same way a λs filter may be used on a profile? Digital Surf's ISO expert François Blateyron sheds light on an important aspect of surface metrology.
