Abstract
A detector for infrared radiation, having a multicell photosensor disposed at the top of a cold finger in an evacuated container, comprises a stack of annular ceramic layers coaxially surrounding the cold finger and serving as supports for several arrays of radially extending metallic strips screen-printed on respective layers in angularly offset relationship. The metallic strips are conductively connected to respective cells of the sensor to serve as output leads thereof. The conductive connections include axially extending metal pins spacedly surrounding the cold finger while being linked with the sensor cells by short, thin wires spanning an intervening annular gap.
