Featuring a 1MP back-thinned CCD, cooled down to -90°C, the ORCA II camera restricts dark current to 0.0012 electrons/pixel/second. This also provides very high quantum efficiency (QE) of greater than 90% across a 200-900nm spectrum.
Extremely long exposure times of up to 120 minutes allows even the faintest light levels to be detected. Programmable trigger signal outputs ensure precise measurement control and data capture.
