Abstract
A light-sensitive detector (1) according to the present invention is constituted by an array (11) of photodetectors, a package (13) on which the array (11) of photodetectors is mounted, and a light-transmissible window (12) for making detection light incident on light-receiving surfaces of the photodetectors. The package (13) is provided with an aperture (14) which is formed in a position adjacent to the photodetectors so that light rays substantially parallel to the detection light can pass through the aperture (14).
