How does IDEX Health & Science cool the sensor?

IDEX Health & Science uses Peltier devices, which are thermoelectric coolers that get cold on one side and hot on the other when electricity is applied. Designing a CCD chamber than can keep a seal for many years is part of the engineering; efficiently dissipating the heat generated by the cooling is another part. Typically the temperature sensor for a camera is installed in a copper block that links the CCD to the Peltier cooler. If there is a problem with contact between the copper block and the sensor, the block may be cold but the sensor may not be fully cooled. In this case, you can see dark current values that are inconsistent with reported temperature of the camera.
