Paper Abstract

METIS is the UV/VIS coronagraph of the ESA mission Solar Orbiter. One of the main technical drivers of the instrument is the detailed stray-light control, as close to the disk edge the VIS coronal emission is six to about seven order of magnitudes lower than the disk one. The instrument testing procedure must then include a measurement of its stray-light rejection capability, which is a fundamental step in the whole instrument calibration / acceptance process. A preliminary optical design of the optical light source for stray-light test is presented. The main requirements are discussed and two possible solutions are outlined.
