ABSTRACT:
A low temperature solid state light detecting system is disclosed. The same incorporates a source of cooling and an electrical light detector. A heat conducting member extends from the detector chip to the source of cooling. A vacuum chamber contains the light detector. The chamber has a window for permitting light to fall on the electrical light detector. A plurality of electrical feedthrough devices are mounted on the chamber for coupling electricity from inside the chamber to the outside of the chamber. A plurality of bare wires extends from the detector to the feedthrough devices positioned on the housing.
