We present the evaluation of the performances of microcameras prototypes manufactured in 3D packaging technology developed for the panoramic camera of the lander for the ROSETTA cometary mission. Two different prototypes were tested, one manufactured by Alcatel and the other by CSEM. A specific laboratory setup with cooling capabilities was implemented to perform electrical, mechanical and photometric tests in the temperature range -90 degrees C to +20 degrees C. Our results show that the photometric performances are nominal and do not change in this temperature range. The reduced size of the camera, associated with its operating mode, leads to a transient thermal behaviour that does not affect the cameras properties when operated at temperatures below -55 degrees C. We show that this kind of miniature camera is suitable to deep space missions like ROSETTA, provided specific cares are taken in the electrical and mechanical designs. (C) 1999 COSPAR.
