Abstract
A low temperature infrared detector for use in a cryostat having a cold finger. A cold plane is mounted upon the cold finger in heat transfer relationship therewith. A read circuit board is mounted upon the cold plane and a detector circuit board is placed over the read circuit and is connected thereto both electrically and thermally. A screen is fitted over the detector circuit board. The screen has a shoulder formed in its bottom wall into which the detection board is press-fitted and a window that frames the detecting circuitry through which the circuitry can be viewed by an IR source. Preferably, the screen is produced using electroforming techniques.
