A HySpex VNIR-1600 sensor, built by NEO and operated by DLR, was extensively characterized in DLR's Calibration Home Base (CHB) and with PTB's PLACOS setup over the course of two years. The generated data significantly extends the characterization performed by the manufacturer, thus allowing to enhance the original raw data calibration method. The improvements concern radiometric characterization, using a well-calibrated radiometric standard, keystone and smile optical distortions, radiometric nonlinearity and spatial and spectral in-band stray light. Since descriptions of the first two measurements were already published, this talk will focus on nonlinearity and stray light. This extensive effort in characterization was undertaken as data from this instrument will be used to validate satellite data and to simulate hyperspectral images of the German EnMAP mission. In particular the contribution of stray light is assessed on the example of a hyperspectral scene of lake Starnberg.
