Accuracy matters just as much to us as to you. Consequently, Viso participates in interlaboratory comparisons as often as we can. These are some of the results.
We are thrilled to share the results of the world’s largest interlaboratory goniometer comparison – the so-called IC2017. The Technical University of Denmark participated with a Viso system. The results […]
Light measurement standards require LED lamps and luminaires to be placed in their normal burning position during measurement. Further, rotation during measurement should be minimized to keep natural cooling. Doing otherwise would certainly lead to gross errors when measuring old […]
A giant international interlaboratory comparison, IC2017, including 37 light measurement laboratories in 18 countries was conducted in 2017 through 2019*. General results are not yet public, participating labs have received their own results. In […]
The Viso LightSpion portable goniometer system was tested at the Technical University of Danish (DTU). Senior scientist Carsten Dam-Hansen (DTU Photonics) tested a series of LED light bulbs in their […]
