Radiometry for Photo-biological safety
The aim of this project is to develop a SI-traceable calibration service to enable evaluation of photobiological safety of lamps and lamp systems, including LED based sources. The increased number of norms, regulations and guidelines (NEN-EN-IEC 62471, NPR-IEC/TR 62471-2, IEC/TR 62778, etc.) designed to protect workers and general public from potentially adverse effect of broad band optical radiation demands extra attention from manufacturers and affects equally already existing processes and products as well as development of new technology. However, light sources, especially LED based, have a diverse applications (medical field, transport, entertainment industry, etc.), which makes evaluation of potential health risks even more complicated, demanding not only an extensive multidisciplinary knowledge but also certain precision of measurement techniques used. Apart of actual user conditions, the final design of the product, including final housing and/or possible input optics, may lead to over/underestimation of relevant hazards, resulting in not only the possible increase of health risks but also a considerable economic impact on manufacturing companies.
Our role
VSL would develop calibration procedure according to relevant photobiological norms and standards with traceability to SI. The technique is based on spectral radiance and irradiance measurements and calculation of permissible exposure times with corresponding uncertainty budget estimation.
Start date: January 1, 2018
End date: December 31, 2023

Virtual experiments and digital twins (ViDiT)
Virtual experiments and digital twins are key enabling technologies to achieve and realise European strategic policies devoted to sustainability and digitalisation within the complex framework of Industry 4.0 and the European Green Deal.
Pushing boundaries of nano-dimensional metrology by light (20FUN02 POLight)
This project addresses this issue by developing novel methods to help bridge the metrology gap and in turn foster KET innovation. More specifically, this project will push the boundaries of optical measurement methods by realising a new generation of optical metrology systems, with unprecedented performances in terms of spatial resolution, traceability, reliability and robustness.
Traceable metrology of soft X-ray to IR optical constants and nanofilms for advanced manufacturing (20IND04 ATMOC)
The optics and semiconductor industries use innovative materials and complex nanostructures in their products whose optical properties are difficult to measure and often not accurately known. This project is developping advanced mathematical methods to traceably characterise these materials for wavelength ranges from soft X-ray to IR.
Traceable industrial 3D roughness and dimensional using optical 3D microscopy and optical distance sensors (20IND07 TracOptic)
To remain competitive, European manufacturers strive to make constant improvements in their manufacturing processes. The surface topography of a component part can have a profound effect on the function of the part. This is true across a wide range of industries (such as precision engineering, automotive and medical).
