Abstract (en)

[origin: WO2019170393A1] The invention relates to a particle sensor (16) comprising: a laser module (18) which has a laser; and a detector (26) designed to detect thermal radiation (14). The particle sensor (16) is characterised in that it has an optical device (36) which is designed to focus laser light emitted from the laser module (18) into a first spot (22), and is designed to focus thermal radiation (14) emitted from the first spot (22) into a second spot, wherein a radiation-sensitive surface of the detector (26) in the second spot or in the beam path of the thermal radiation (14) focussed onto the second spot is behind the second spot.
