Abstract
A shield for limiting the radiation received by individual detectors within a detector array of an electromagnetic radiation detection system to the radiation provided to the detectors by the optics of the system. The shield comprises a member of etchable glass having apertures formed therein, the position of the aperture edges being in predetermined relation to the edges of the detectors for shielding the detectors from electromagnetic radiation generated outside the field of view of the optics.
