The radiation detector, particularly a pyroelectric IR radiation detector, comprises a housing (10) containing a radiation detector element together with additional circuit components if required, which housing consists of a moulded, preferably single piece, three dimensional printed circuit having conductive tracks (18a-f) extending at surface regions thereof through which external electrical connection with the element can be made. The element can be mounted directly on the tracks. An opening (12) in the housing (10) over the detector element is closed by a silicon window. The detector may comprise electrical leads (20-22) either partly embedded in the housing and contacting respective tracks or in engagement with tracks on the surface of the circuit. Alternatively, tracks may define external contact pads. The tracks can be provided in two layers, one of which is at the surface. One track (34) may be of extended area and serve as an electrical screen. <IMAGE> |
