Our focus is on non-contact measurements with emphasis on optical and laser measurements. The applications are covering a very broad field that can be found in scientific and fundamental metrology, within applied, technical or industrial fields and legal & forensic applications. Optical and laser measurements can generally be divided into three basic activities;   – definition of internationally accepted units of measurement – realisation of these units of measurement in practice       – application of chains of traceability linking to reference standards

Optical surface profilers

The instruments are high-precision and non-contact tools for characterizing the surface topography in 3D. The highlights are: areal measurement with nm vertical resolution, large field-of-view (FOV) for large samples, measure hard-to-reach areas like holes, fast measurement for short cycle times. TopMap systems measures parameters like step-height, waviness, flatness, parallelism, as well as roughness

Hyperspectral Imaging

While a regular camera records three spectral channels in every pixel (red, green, and blue), hyperspectral imagers have the ability to record hundreds of spectral channels. Hyperspectral imaging is measuring a continuous reflectance spectrum in every pixel in a 2D image. As different materials have different reflectance spectra, the technique enables us to identify different…
