A cold shield for an array of detectors of predetermined shape comprising a first cover of radiation blocking material formed with parallel rows of apertures and lying a first distance away from the detectors and a second cover of radiation blocking material formed with a plurality of apertures of generally the predetermined shape therethrough and lying a second distance, smaller than the first distance, away from the detectors so as to minimize background radiation from reaching the detectors while permitting desired radiation approaching the array from any of a plurality of angles to reach the detectors.

Tilted array with parallel cold shield

An ultraviolet sensitive photodiode is formed in a body of first conductivity type GaP. A region of second conductivity type with a graded impurity distribution is formed in the body, and a thin layer (preferably about 100A to 300A) is then removed from the front surface of the body. The removal of the thin layer significantly enhances the performance of the UV sensitive photodiode.

Method of making a gap UV photodiode by multiple ion-implantations

Pyroelectric detectors are mounted on a substrate having a plurality of wax-filled cavities. The wax is then dissolved to provide a low thermal loss mounting structure for the detectors.
