Dewar cold finger
WebThe cold finger ground lug is for optional use, to ground the detector separately from the dewar. Some detectors include a temperature sensor, which may also be used to ground the detector. Normally this ground is not required; the ground lug may be left unconnected. WebMetallurgical bond 46 hermetically seals the end-cap 28 to the cold end 24 of coldfinger 22 to provide a strong, thermally conductive bond which preserves vacuum integrity within dewar cavity 39. Receiving thermal energy form the dewar assembly 40 and the detector 30 is the coldfinger 22.
