Abstract

A scattered light detector for the detection of particles, having a test section with a flow inlet and a flow outlet for forming a flow path through which the test fluid can flow, a light transmitter, which transmits a light beam in a radiation direction, with the transmitted light beam forming an intersection region with the flow path, a light receiver for receiving a scattered light fraction scattered on smoke particles in the intersection region, and a printed circuit board. The light transmitter and the light receiver are connected to the printed circuit board, with the light beam transmitted by the light transmitter being guided into the test section by means of an optical fiber deflecting the light beam, and the light receiver is arranged in such a manner that a direct or indirect scattered light path runs between the light receiver and the intersection region.
