Abstract

A particle sensor is described. The particle sensor includes a laser module having a laser, and a detector configured to detect thermal radiation. The particle sensor has an optical apparatus that is configured to focus laser light proceeding from the laser module into a first spot and is configured to focus thermal radiation proceeding from the first spot into a second spot, a radiation-sensitive surface of the detector being located in the second spot, or behind the second spot in the beam path of the thermal radiation focused onto the second spot.
