HERSCHEL is a suborbital mission which will observe the solar corona in the UV and visible light by means of two coronagraphs and an EUV imager. One of the two coronagraphs is SCORE (Sounding CORonagraphic Experiment), developed mainly by some Italian scientific institutions. SCORE performs imaging of the extended corona from 1.4 to 4 solar radii in the broadband visible and in the UV lines HI 121.6 nm and HeII 30.4 nm. The CCD visible camera (VLD) of SCORE has been designed, built and characterized at the XUVLab of the University of Florence. In this paper we will describe the VLD calibration and testing performed before launch in order to evaluate the performances of SCORE.
