Abstract
The European ESA EUCLID dark energy, dark matter mission is presented with respect to the near instrument optics. We present the nominal optics approach as well as the tolerancing concept and the results of this tolerancing. through this we are able to show that the merged near infrared spectrometer and photometer NISP can be built with high image quality in a sophisticated but well performing approach. Furthermore a ghost analysis for NISP is presented, showing that reflective ghost have been successfully suppressed during the optimization process.
