Three highresolution chargecoupleddevice (CCD) cameras are cooled to operate with very lowdarkcurrent noise levels in lowlight applications such as fluorescence microscopy. Twostage Peltier cooling lowers the sensor temperature 55°C to allow extended integration times and improve dynamic range and signaltonoise ratio. The vacuumsealed CCD sensor prevents condensation when cooled, and convection removes heat without liquid heat transfer or vibration from fans.
