detector-Dewar assembly

A detector enclosure, evacuated of air and cooled to temperatures below ambient. A cold shield limits the solid angle viewed by the sensor. A cold filter, if used, limits the spectral bandpass. By operating at cryogenically cooled temperatures, the sensing elements can more readily detect small differences in temperature.
