Title (EN) OPTICAL PARTICLE COUNTER
(FR) COMPTEUR OPTIQUE DE PARTICULES
Abstract:
(EN) An optical particle counter ( 100 ) includes a light source, an integrating sphere (104), a light stop (105), a photo-detector (106), a channel for air inlet ( 107 ), and a channel for air outlet (108). The light source is arranged to focus the light beam in the center of the integrating sphere (104), The light stop (105) is arranged to stop the light beam after exiting the integrating sphere (104 ). The channels for air inlet (107) and outlet ( 108 ) are configured to allow an aerosol sample to enter the integrating sphere ( 104 ), cross the light beam, and exit.
(FR) Un compteur optique de particules (100) comprend une source de lumière, une sphère d'intégration (104), un dispositif arrêtant la lumière (105), un photo-détecteur (106), une conduite d'admission d'air (107) et une conduite de sortie d'air (108). La source de lumière est agencée de manière à focaliser le faisceau de lumière au centre de la sphère d'intégration (104). Le dispositif arrêtant la lumière (105) est agencé de manière à arrêter le faisceau de lumière après sa sortie de la sphère d'intégration (104). Les conduites d'admission (107) et de sortie (108) d'air sont conçues de manière à permettre à un échantillon d'aérosol de pénétrer dans la sphère d'intégration (104) et de traverser le faisceau de lumière avant de sortir de la sphère d'intégration.
