The new CCD Controller for Counting Photons of Photon etc. has been integrated with a CCD97 EMCCD from e2v technologies into a scientific camera at the Laboratoire d’Astrophysique Expérimentale (LAE), Université de Montréal to develop the world’s most sensitive astronomical camera. This unique EMCCD camera achieves subelectron readout noise and very low clock-induced charge (CIC) levels, which are mandatory for extreme faint flux imaging. It has been characterized in laboratory and used on the Observatoire du Mont Mégantic 1.6 m telescope. The National Aeronautics and Space Administration (NASA) was so much impressed by its results that the NASA purchased the first commercial CCD controller of Photon etc (CCCP). “The sensitivity of the cameras developed will not only help to understand better the depths of the universe but also to perceive weak optical signals coming from the human body. These signals can reveal the early signs of several diseases such as macular degeneration and certain types of cancer. An early diagnostic leads to early intervention, hopefully before the disease becomes more serious thus saving lives and important costs,” says Sébastien Blais-Ouellette, president of Photon etc.
