摘要
A calibration device for calibrating a scattered-light meter, which is developed for measuring a particle concentration, in particular in automotive exhaust gases, has at least one diffuser which emits scattered light of an intensity and distribution defined by the diffuser when irradiated by light. In addition, the calibration device has a calibration-light source, which is situated within the diffuser or on an external surface of the diffuser.
