Spectrum Logic has now released water-cooled versions of the 2824HR and 2824HS detectors to further improve their market leading performance. In the cooled detectors water circulates between a chiller unit and a heat exchanger in the detector housing. This cools the detector and maintains a stable temperature which is configured at the chiller. The stable temperature reduces dark noise and stability of the temperature of the sensor array means that the offset correction is stable and does not suffer from variations in the dark image due to temperature changes in the CMOS sensors in the detector.
