Stay up to-date with the latest imaging, analysis and metrology news from Digital Surf.
The combination of a high-pass filter and a low-pass filter may be used to establish a narrow bandwidth which can help to study surface behavior at a particular scale. François Blateyron provides further explanations on this type of filtering, a tool for which is released with Mountains® 9.2.
The GPS matrix is a convenient way of classifying standards in the various chain links of the specification-verification chain. François Blateyron provides further explanations.
Version 9 of Mountains® software sees the introduction of support for several new data types, including multi-channel cubes. Christophe Mignot, Digital Surf CEO, explains the nature of this new kind of “studiable” and highlights the main applications and advantages for users.
The next few months will see the validation of a revised version of the ISO 25178-2 standard, defining parameters and specifications for areal surface texture analysis . Digital Surf’s senior surface metrology expert François Blateyron outlines the changes to come.
Surface texture specifications are indicated using the root symbol. The new ISO 21920-1 series will soon bring changes that may modify common practices. Our senior metrology expert explains.
Stochastic and deterministic are two terms that are used more and more frequently to qualify modern surfaces. What is their meaning? Digital Surf’s senior metrology expert François Blateyron explains.
When results differ, which ones can be trusted? Proving that an algorithm is correct is not so straightforward. François Blateyron, senior expert on surface metrology, discusses this complex issue.
François Blateyron, Digital Surf’s expert on surface metrology, examines the next big change in surface analysis: freeform surfaces.
R&W motifs (ISO 12085) are soon to be included in the revision of profile standards (ISO 21290). François Blateyron, Digital Surf’s surface metrology expert explains.
With the release of Mountains® 8 comes the possibility to load and visualize a new kind of data, known as “Shells” or “Freeform surfaces”. Christophe Mignot takes a closer look at this new data type.
Surface texture has always been a difficult discipline to master, due to complex filtration conditions and numerous parameters. ISO expert François Blateyron looks how this could be simplified in the future.
Sometimes objects in SEM images are quite complex and you may have trouble colorizing them. Learn how to adjust settings of the click and color tool to colorize complex objects in SEM images.
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.
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.
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.
