SnapScan VNIR for imaging spectroscopy

The imec SnapScan VNIR camera is mounted in one of the imaging cabinets in the NPEC greenhouse conveyor system. The integration of this camera was done by SMO – WIWAM,  in which the camera can be mechanically mounted in top-view or in side-view orientation. This camera was integrated in collaboration with the OnePlanet Research Centre.
