Recent advances in optical roughness measurement have fundamentally transformed surface metrology \u2013 now achieving measurement rates of several million points per second.
The latest optical profilers capture complex surfaces rapidly, with high resolution, and in full compliance with ISO 21920.<\/p>\n

In an Sc3 scenario, a measurement area of 4 \u00d7 4 mm\u00b2 with a point density of 0.5 \u00b5m corresponds to an impressive 64 million measurement points<\/strong>, captured in under 30 seconds<\/strong>.
These highly sophisticated systems allow the use of specified filters (\u03bbs and \u03bbc) without compromise \u2013 comparable to traditional tactile roughness measurement methods.
At the same time, they enable extensive three-dimensional analysis capabilities that allow structures, deviations, and defects to be precisely identified.
The ability to measure even the smallest features with significantly higher resolution greatly enhances the quality and reliability of analysis results.<\/p>\n

With the extended capabilities of modern high-speed profilers, the typical limitations of earlier systems are eliminated.
Say goodbye to restricted measurement ranges and insufficient resolution \u2013 and experience a new era of precise, efficient, and non-contact surface profiling and roughness measurement.<\/p>\n <\/div>\r\n <\/div>\r\n

Why use roughness evaluation?<\/h2>\r\n <\/div>\r\n
\r\n

Within the TracOptic project, it was found that surface effects account for around 10% of all component failures<\/strong> \u2013 with significant economic impact.
Modern optical profilometers make a decisive contribution by precisely identifying the causes of such failures, reducing time and cost in production.<\/p>\n

Most machined surfaces fall within setting class Sc3 and require, for ISO-compliant roughness evaluation, a 4 mm profile length<\/strong> and a spatial sampling of 0.5 \u00b5m<\/strong>.
The latest generation of smartWLI profilometers<\/strong> offers a significant performance boost for roughness measurement:
With several million measurement points per second, areas of 4 \u00d7 4 mm\u00b2<\/strong> can now be captured at a 0.5 \u00b5m sampling rate<\/strong>(equivalent to 64 million points) within just a few seconds.<\/p>\n

This high data density enables the transition from traditional 2D profile evaluation to true 3D roughness assessment<\/strong> \u2013 without any compromise in measurement length or resolution.<\/p>\n <\/div>\r\n <\/div>\r\n
