Scanning software provides fast results
NanoFocus usurf technology is based on fast optical filtering carried out by a confocal spatial filter.
Usurf analysis surface analysis software based upon the new version 5 of Digital Surf's Mountains technology has been integrated into NanoFocus' usurf 3D topometers and uscan profilometers The usurf 3D topometer from NanoFocus is used by laboratories that measure and test 3D technical surfaces with micro and nano-dimensional structures
Measurement data is available in a few seconds for analysis from the integrated usurf analysis software, based on Digital Surf's Mountains technology.
Stand-alone and network versions of the software are available on three levels to meet different user requirements.
NanoFocus usurf technology is based on fast optical filtering carried out by a confocal spatial filter.
The usurf 3D topometer uses a fast confocal imaging technique to capture precise, sharp three-dimensional images of surface topography in a single fast measurement operation.
Equipped with a precise computer-controlled objective lens drive, the usurf generates height sections at different working distances.
Only components of reflected light that are in focus are captured by the CCD camera sensor.
Out of focus components are blocked by special multipinhole filters.
The height sections are stored consecutively in an image stack and a special software algorithm calculates the 3D topography.
NanoFocus usurf technology provides excellent resolution and it is robust for use both in laboratories and on the shop floor.
Enhanced contrast and optimal lateral resolution obtained by the usurf guarantee excellent reproduction of steep edges and complex rough surfaces.
Accurate measurements on rough surfaces agree absolutely with reference results generated using mechanical-tactile techniques, but noncontact measurement with the usurf means that there is no risk of damaging the surface under study.
The usurf analysis software is continuously updated to include the latest industry standards and methods and to incorporate innovations from Digital Surf's specialists in surface metrology.
A comprehensive range of 2D and 3D parameters and filtering techniques are available, including 3D parameters defined in the new ISO 25178 standard, the first international standard on a real surface texture and advanced filtering techniques defined in the ISO 16610 standard.
Working in usurf analysis' intuitive multilanguage desktop publishing style environment, the user builds an accurate metrological report step by step, frame by frame.
An analysis workflow documents every step in the analysis and provides full metrological tracability.
The user can add a new step, fine tune a step or delete a step at any time.
Everything is recalculated automatically.
A finished document can be used as a template for analysing other measurement data sets.
Minidocs (pre-defined sequences of analysis steps or macros) can also be created for use in an analysis document to save time.
The usurf analysis software provides powerful 3D visualisation based on OpenGL technology, making it possible to manipulate a 3D surface and zoom in on a detail in real-time.
Any texture image or photo can be superimposed on the 3D topography.
A comprehensive range of features include dimensional control, a complete set of filters for removing form and separating different frequencies, studies of functional aspects of a surface, granulometry (studies of particles, grains, bumps, holes, islands) and tools for spectral analysis, isotropy, directionality, periodicity, auto-correlation and fractal analysis.
In particular, nonmeasured points are handled seamlessly by all usurf analysis applications.
For example it is possible to calculate any parameter on a surface containing nonmeasured points or on a profile that is extracted from it.
The software also contains intelligent tools for filling in nonmeasured points.
Images, text and videos of simulated flights over surfaces can be exported in standard formats for interfacing with third-party software and systems.
