Abstract
A device includes a substantially planar platform. The device also includes a detector connected to the platform. The device further includes multiple cold fingers including a first cold finger and a second cold finger. Each cold finger has an end portion connected to the platform. Each cold finger is configured to be fluidly coupled to a corresponding cryocooler. Each cold finger is configured to absorb thermal energy generated by the detector. The second cold finger has a flexure region at the end portion.
