van den Berg, S. (author), Dekker, P. (author), van der Laan, T. (author), Otter, G.C.J. (author), Dijkhuizen, N. (author), Gür, B. (author), Brinkers, S. (author)SI traceable calibration of satellite instruments like spectroradiometers get increasingly important in space-based observation for various reasons. First, requirements on measurements in terms of accuracy, dynamic range and wavelength range get increasingly demanding. Second, long term observations require SI traceability for comparability of...conference paper 2018

(author), Ricardo, J. (author), Barroqueiro, B. (author)Additive Manufacturing (AM) technology has shown impressive new opportunities and convincing results over the last years, mainly in terrestrial applications. Today, it has proven to represent a completely new approach to shape complex mechanical parts, with enormous potential for optimization of dedicated parameters. Numerous possibilities shine...conference paper 2018

(author), Spruit, W.E.T. (author), Brinkers, S. (author), Human, J.D. (author)To increase the collecting power and to improve the angular imaging resolution, space telescopes are evolving towards larger primary mirrors. The aerial density of the telescope mirrors needs to be kept low, however, to be compatible with the launch requirements. A light-weight (primary) mirror will introduce additional optical aberrations to...conference paper 2017

(author)The Global Ozone Monitoring Experiment-2(GOME-2) represents one of the European instruments carried on board the MetOp satellite within the ESA’s “Living Planet Program”. Consisting of three flight models (FM’s) it is intended to provide long-term monitoring of atmospheric ozone and other trace gases over a time frame of 15–20 years, thus...conference paper 2017

(author)Over the last decade TNO has developed a deformable mirror concept using electromagnetic actuators with the main advantages of having very low non-linearity and hysteresis, low power consumption, and high inherent reliability of the actuators. TNO recently started a program to redesign the electromagnetic actuator to improve the actuator...conference paper 2016

Gür, B. (author), Otter, G.J.C. (author), Jansen, R. (author), Groote Schaarsberg, J.J.M. (author), Brinkers, S. (author)Optical components with scattering properties, so-called diffusers, are core elements of calibration units in earth observation instruments. Their performance influences significantly the achievable accuracy of scientific observations. It is of high importance however to characterize the scattering properties of such a diffuser with minimum...conference paper 2015
