A cold finger will provide temperature differentials at the sensor in the order of 20 - 30C depending on design. And there is the option of temperature regulation. The latest iteration when complete will have a real differential of 20 - 23C, allowing for sensor face heating. The modified cooling algorithm smoothly maintains +/- 1C at the temperature sensor, with a resolution of < 0.3C. I imagine the camera sensor/cold finger/PCB total mass will fluctuate less, be less dynamic, due to its thermal mass. Real time, regulated cooling.
