Abstract

Modern infrared radiation detectors have a coverage angle of up to 180 DEG . Such a wide coverage angle is not always required, since interfering sources which are located outside the area under surveillance are occasionally detected in its peripheral area. The new radiation detector is intended to enable simple restriction of the coverage angle and can be adapted, if necessary, to changing conditions. <??>According to the invention, a detector casing (1) is provided with a frame (5), in which a guide channel (7) is formed which is suitable for the accommodation of a closable covering element (6). The covering element (6) can be pushed in front of an optical system (3) so that the coverage angle ( alpha 1) of the latter is reduced to a coverage angle ( alpha 2). <??>The invention is preferably employed in passive infrared detectors which are used for area surveillance. <IMAGE>
