CPng: a high sensitivity photon-counting camera

CPng is a photon-counting camera currently under final development at Observatoire de Lyon, France and Observatoire de la Cote d Azur, France. Its goal is to provide quantum efficiency as high as possible at visible wavelengths up to 30-35 %under very low light level conditions and with a very short exposure time, approximately 4ms. Five CPng devices are under construction for astronomical and bio-medical imaging.
