Cooling a Digital Camera?

Posted by Cliff on from the cryogenic-photogenic dept.

thusson asks: "I work at a lab doing intrinsic signal imaging of cat and mouse visual cortex (brains). We are using a Dalsa 1M60P camera, and we want to cool it about 30-50 degrees C to improve picture quality by reducing noise. Does anyone have any suggestions about how to do this? So far, heat sinks have helped but only by a few degrees. I figure the overclocking community is a good place for novel ideas."

    What should you be cooling? How are you measuring your temp? Answers to these questions will drastically change the answer.

    30-50 degrees Celsius?

    #1 - Is your claim valid

    #2 - Will the camera work at that temperature

    #3 - Try some liquid nitrogen. Or, some spray dusters turned upside down.

      FYI, liquid nitrogen is SIGNIFICANTLY below 30-50C.
      Quick run in the head is somewhere from 86F to 122F. Not sure how hot the body temperature of your average mouse is though.

      This guy got it right by asking what exactly they need cooled, and for what ends?

    What makes you think that heat sinks will lower the temperature by 30-50 C? At best, heat sinks will lower the temperature to that of the surrounding room.

    If you want something cooler, you'll need to use Dry Ice or refridgeration or some external input.

    Peltiers are probably your best best. You'll need to mount heat sinks on the hot sides to radiate off the waste heat, but you can get a good 60-70 C temp difference between the hot and cold sides.

    There's a good example here
