Abstract
A cold shield of a cryogenic camera. The cold shield reflects external thermal radiation away from the cryogenic camera, so as to shield the cryogenic camera in a cryogenic temperature such that no internal thermal radiation will be generated. The cryogenic camera has a lens assembly and a focal plane array. The cold shield has an upper cold shield member for holding the lens assembly and a lower cold shield member for holding the focal plane array. The upper cold shield member fits over the lower cold shield member by contact friction, such that limited translation and rotation of the lower cold shield member relative to the upper cold shield member are allowable. Therefore, the cold shield allows a fine adjustment for aligning the lens assembly to the focal plane array.
