Geoptik CCD cooling fan

17 October 2015 Steve Ringwood

CCDs are incredible devices, gobbling photons that have travelled the vastness of space with great efficiency. Their Achilles heel is to also accept spurious signals from the immediate vicinity — within their own traitorous circuitry. Steve Ringwood investigates a CCD cooling chamber that will reduce a camera’s noise and increase its efficiency for both daytime and nocturnal imaging.
